Value, Momentum and Carry – Is it time for equity investors to switch?

  • Index tracking and growth funds have outperformed value managers for several years
  • Last month value was resurgent, but will it last?
  • In the long run, value has offered a better risk adjusted return
  • The long-term expected return from growth stocks remains hard to assess

Value, momentum and carry are the three principal means of extracting return from any investment. They may be described in other ways but these are really the only games in town. I was reminded of this during the last month as value based equity managers witnessed a resurgence of performance whilst index tracking products generally suffered. Is this a sea-change or merely a case of what goes up must come back down?

My premise over the last few years has been that the influence of central banks, in reducing interest rates to zero or below, has been the overwhelming driver of return for all asset classes. The stellar performance of government bonds has percolated through the credit markets and into stocks. Lower interest rates has also made financing easier, buoying the price of real-estate.

Traditionally, in the equity markets, investment has been allocated to stocks which offer growth or income, yet with interest rates falling everywhere, dividend yields offer as much or more than bonds, making them attractive, however, growth stocks, often entirely bereft of earnings, become more attractive as financing costs approach zero. In this environment, with asset management fees under increasing pressure, it is not surprising to observe fund investors accessing the stock market by the cheapest possible means, namely ETFs and index tracking funds.

During the last month, there was a change in mood within the stock market. Volatility within individual stocks remains relatively high, amid the geo-political and economic uncertainty, but value based active managers saw a relative resurgence, after several years in the wilderness. This may be merely a short-term correction driven more by a rotation out of the top performing stocks, but it could herald a sea-change. The rising tide of ever lower interest rates, which has floated all ships, may not have turned, but it is at the stand, value, rather than momentum, may be the best means of extracting return in the run up to the US presidential elections.

A review of recent market commentary helps to put this idea in perspective. Firstly, there is the case for growth stocks, eloquently argued by Jack Neele at Robeco – Buying cheap is an expensive business: –

One of the most frequent questions I have been asked in recent years concerns valuation. My focus on long-term growth trends in consumer spending and the companies that can benefit from these often leads me to stocks with high absolute and relative valuations. Stocks of companies with sustainability practices that give them a competitive edge, global brand strength and superior growth prospects are rewarded with an above-average price-earnings ratio.

It is only logical that clients ask questions about high valuations. To start with, you have the well-known value effect. This is the principle that, in the long term, value stocks – adjusted for risk – generate better returns that their growth counterparts. Empirical research has been carried out on this, over long periods, and the effect has been observed in both developed and emerging markets. So if investors want to swim against the tide, they need to have good reasons for doing so.

In addition, there are – understandably – few investors who tell their clients they have the market’s most expensive stocks in their portfolio. Buying cheap stocks is seen as prudent: a sign of due care. However, if we zoom in on the last ten years, there seems to have been a structural change since the financial crisis. Cheap stocks have done much less well and significantly lagged growth stocks.

Nevertheless, holding expensive stocks is often deemed speculative or reckless. This is partly because in the financial industry the words ‘expensive’ and ‘overvalued’ are often confused, despite their significant differences. There are many investors who have simply discarded Amazon shares as ‘much too expensive’ in the last ten years. But in that same period, Amazon is up more than 2000%. While the stock might have been expensive ten years ago, with hindsight it certainly wasn’t overvalued.

The same applies for ‘cheap’ and ‘undervalued’. Stocks with a low price-earnings ratio, price-to-book ratio or high dividend yield are classified as cheap, but that doesn’t mean they are undervalued. Companies in the oil and gas, telecommunications, automotive, banking or commodities sectors have belonged to this category for decades. But often it is the stocks of these companies that structurally lag the broader market. Cheap, yes. Undervalued, no.

The author goes on to admit that he is a trend follower – although he actually says trend investor – aside from momentum, he makes two other arguments for growth stocks, firstly low interest rates and secondly the continued march of technology, suggesting that investors have become much better at evaluating intangible assets. The trend away from older industries has been in train for many decades but Neele points out that since 1990 the total Industry sector weighting in the S&P Index has fallen from 34.9% to 17.3% whilst Technology has risen from 5.9% to 15.6%.

If the developed world is going to continue ageing and interest rates remain low, technology is, more than ever, the answer to greatest challenges facing mankind. Why, therefore, should one contemplate switching from momentum to value?

A more quantitative approach to the current environment looks at the volatility of individual stocks relative to the main indices. I am indebted to my good friend Allan Rogers for his analysis of the S&P 100 constituents over the past year: –

OEF, the ETF tracking the S&P 100, increased very modestly during the period from 9/21/2018 to 9/20/2019.  It rose from 130.47 to 132.60, a gain of 1.63%.  During the 52 weeks, it ranged between 104.23 and 134.33, a range of 28.9% during a period where the VIX rarely exceeded 20%.  Despite the inclusion of an additional 400 companies, SPY, the ETF tracking the S&P 500, experienced a comparable range of 29.5%, calculated by dividing the 52 week high of 302.63 by the 52 week low of 233.76.  SPY rose by 2.2% during that 52 week period.  Why is this significant?  Before reading on, pause and make your own estimate of the average 52 week range for the individual stocks in the S&P 100.  15%?  25%?  The average 52 week price range for the components was 49%.  The smallest range was 18%.  The largest range was 134%.  For a portfolio manager tasked with attempting to generate a return of 7% per annum, the 100 largest company stocks offer potential profit of seven times the target return if one engages in active trading.  Credit risk would appear to be de minimus for this group of companies.  This phenomenon highlights remarkable inefficiency in stock market liquidity.

This analysis is not in the public domain, however, please contact me if you would like to engage with the author.

This quantitative approach when approaching the broader topic of factor investing – for a primer Robeco – The Essentials of Factor Investing – is an excellent guide. Many commentators discuss value in relation to investment factors. Last month an article by Olivier d’Assier of Axioma – Has the Factor World Gone Mad and Are We on the Brink of Another Quant Crisis? caught my eye, he begins thus: –

To say that fundamental style factor returns have been unusual this past week would be the understatement of the year—the decade, in fact. As reported in yesterday’s blog post “Momentum Nosedives”, Momentum had a greater-than two standard deviation month-to-date negative return in seven of the eleven markets we track. Conversely, Value, which has been underperforming year-to-date everywhere except Australia and emerging markets, has seen a stronger-than two standard deviation month-to-date positive return in four of those markets. The growth factor also saw a sharp reversal of fortune last week in the US, while leverage had a stronger-than two standard deviation positive return in that market on the hopes for more monetary easing by the Fed.

The author goes on to draw parallels with July 2007, reminding us that after a few weeks of chaotic reversals, the factor relationships returned to trend. This time there is a difference, equities in 2007 were not a yield substitute for bonds, today, they are. Put into the context of geopolitical and economic growth concerns, the author expects lower rates and sees the recent correction in bond yields as corrective rather than structural. As for the recent price action, d’Assier believes this is due to unwinding of exposures, combined with short-term traders buying this year’s losing factors, Value and Dividend Yield, and selling winners such as Momentum and Growth. Incidentally, despite the headline, Axioma does not envisage a quant crisis.

Returning to the broader topic of momentum versus value, a recent article from MSCI – Growth’s recent outperformance was and wasn’t an anomaly – considers whether the last decade represents a structural shift, here is their summary: –

Growth strategies have performed well over the past few years. For investors, an important question is whether the recent performance is an anomaly.

For a growth strategy that simply picks stocks with high growth characteristics, the recent outperformance is out of line with that type of growth strategy’s historical performance.

For a strategy that targets the growth factor while controlling for other factors, the recent outperformance has been in line with its longer historical performance.

The chart below attempts to show the performance of the pure growth factor adjusted for non-growth factors: –

GrowthFactors_Exhibit_2

Source: MSCI

If anything, this chart shows a slightly reduced return from pure growth over the last three years. The authors conclude: –

…to answer whether growth’s recent performance is an anomaly really depends on what we mean by growth. If we mean a simple strategy that selects high-growth stocks, then the recent performance is not representative of that strategy’s long-term historical performance. In this case, we can attribute the recent outperformance relative to the long term to non-growth factors and particular sectors — exposure to which has not been as detrimental recently as it has been over the long run. But for a factor- and sector-controlled growth strategy, the performance is mainly driven by exposure to the growth factor. In this case, the recent outperformance has been in line with the longer-term outperformance.

As I read this I am reminded of a quant hedge fund manager with whom I used to do business back in the early part of the century. He had taken a tried a tested fundamental short-selling strategy and built a market neutral, industry neutral, sector neutral portfolio around it, unfortunately, by the time he had hedged away all these risks, the strategy no longer made any return. What we can probably agree upon is that growth stocks have outperformed income and value not simply because they are growth stocks.

The Case for Value

They say that history is written by the winners, nowhere is this truer than in investment management. Investors move in herds, they want what is hot and not what is not. In a paper published last month by PGIM – Value vs. Growth: The New Bubble – the authors’ made several points, below are edited highlights (the emphasis is mine): –

  1. We have been through an extraordinary period of value factor underperformance over the last 18 months. The only comparable periods over the last 30 years are the Tech Bubble and the GFC.

  2. Historically, we would expect a very sharp reversal of value performance to follow. This was the case in each of the two previous extreme periods.

  3. We tested the drivers of recent value underperformance to see if we are in a “value trap.” Historically, fundamentals have somewhat deteriorated, but prices expected a bigger deterioration, so the bounce-back more than offset the fundamental deterioration. In a value trap environment, we would expect a greater deterioration in fundamentals. In the last 18 months, we have actually seen an improvement in fundamental earnings for value stocks, but a deterioration in pricing. This combination is unprecedented, and signals the opposite of a value trap environment.

  4. …we examined the behavior of corporate insiders… The relative conviction of insiders regarding cheaper stocks is higher than ever, which reinforces our conviction about the magnitude of the performance opportunity from here.

  5. It is never easy to predict what it will take to pop a bubble, but there are multiple scenarios that we envisage as potential catalysts, including both growth and recessionary conditions.

These views echo an August 2019 article by John Pease at GMO – Risk and Premium – A Tale of Value – the author concludes (once again the emphasis is mine): –

Value has underperformed the market in 10 of the last 12 months, including the last 7. Its most recent drawdown began in 2014 and the factor is quite far from its high watermark. The relative return of traditional value has been flat since late 2004. All in all, it has been a harrowing decade for those who have sought cheap stocks, and we have tried to understand why.

We approached this problem by decomposing the factor’s relative returns. The relative growth profile of value has not changed with time; the cheapest half (ex-financials) in the U.S. has continued to undergrow the market, but by no more than what we have come to expect. These companies have also not compromised their quality to keep growth stable, suggesting that any shifts that have occurred in the market have not disproportionately hurt value’s fundamentals.

The offsets to value’s undergrowth, however, have come under pressure. Value’s yield advantage has fallen as the market has become more expensive. The group’s rebalancing – the tendency of cheap companies to see their multiples expand and rotate out of the group while expensive companies see their multiples contract and come into value – is also slower, with behavioral and structural aspects both at play. Though these drivers of relative outperformance have diminished, they still exceed value’s undergrowth by more than 1%, indicating that going forward, cheap stocks (at least as we define them) are likely to reap a decent, albeit smaller, premium.

This premium has not materialized over the last decade for a simple reason: relative valuations. Value has seen its multiples expand a lot less than the market. This makes sense – because value tends to have significantly lower duration than other equities, a broad risk rally shouldn’t be as favorable to cheap stocks as it should be to their expensive counterparts. And we have had quite a rally.

It isn’t possible to guarantee that the next decade will be kinder to value than the previous one was. The odds would seem to favor it, however. Cheap stocks still provide investors with a premium, allowing them to outperform even if their relative valuations remain low. If relative valuations rise – not an inconceivable event given a long history of mean-reverting discount rates – the ensuing relative returns will be exceptional. And value, after quite the pause, might look valuable again.

A key point in this analysis is that the low interest rate environment has favoured growth over value. Unless the next decade sees a significant normalisation of interest rates, unlikely given the demographic headwinds, growth will continue to benefit, even as momentum strategies falter due to the inability of interest rates to fall significantly below zero (and that is by no means certain either).

These Macro Letters would not be In the Long Run without taking a broader perspective and this July 2019 paper by Antti Ilmanen, Ronen Israel, Tobias J. Moskowitz, Ashwin Thapar, and Franklin Wan of AQR – Do Factor Premia Vary Over Time? A Century of Evidence – fits the bill. The author examine four factors – value, momentum, carry, and defensive (which is essentially a beta neutral or hedged portfolio). Here are their conclusions (the emphasis is mine): –

A century of data across six diverse asset classes provides a rich laboratory to investigate whether canonical asset pricing factor premia vary over time. We examine this question from three perspectives: statistical identification, economic theory, and conditioning information. We find that return premia for value, momentum, carry, and defensive are robust and significant in every asset class over the last century. We show that these premia vary significantly over time. We consider a number of economic mechanisms that may drive this variation and find that part of the variation is driven by overfitting of the original sample periods, but find no evidence that informed trading has altered these premia. Appealing to a variety of macroeconomic asset pricing theories, and armed with a century of global economic shocks, we test a number of potential sources for this variation and find very little. We fail to find reliable or consistent evidence of macroeconomic, business cycle, tail risks, or sentiment driving variation in factor premia, challenging many proposed dynamic asset pricing theories. Finally, we analyze conditioning information to forecast future returns and construct timing models that show evidence of predictability from valuation spreads and inverse volatility. The predictability is even stronger when we impose theoretical restrictions on the timing model and combine information from multiple predictors. The evidence identifies significant conditional return premia from these asset pricing factors. However, trading profits to an implementable factor timing strategy are disappointing once we account for real-world implementation issues and costs.

Our results have important implications for asset pricing theory, shedding light on the existence of conditional premia associated with prominent asset pricing factors across many asset classes. The same asset pricing factors that capture unconditional expected returns also seem to explain conditional expected returns, suggesting that the unconditional and conditional stochastic discount factors may not be that different. The lack of explanatory power for macroeconomic models of asset pricing challenges their usefulness in describing the key empirical factors that describe asset price dynamics. However, imposing economic restrictions on multiple pieces of conditioning information better extracts conditional premia from the data. These results offer new features for future asset pricing models to accommodate.

This paper suggests that, in the long run, broad asset risk premia drive returns in a consistent manner. Macroeconomic and business cycle models, which attempt to forecast asset values based on expectations for economic growth, have a lower predictive value.

Conclusions and investment opportunities

I have often read market commentators railing against the market, complaining that asset prices ignored the economic fundamentals, the research from AQR offers a new insight into what drives asset returns over an extended time horizon. Whilst this does not make macroeconomic analysis obsolete it helps to highlight the paramount importance of factor premia in forecasting asset returns.

Returning to the main thrust of this latter, is this the time to switch from momentum to value? I think the jury is still out, although, as the chart below illustrates, we are near an all-time high for the ratio between net worth and disposable income per person in the US: –

This is a cause for concern, it points to severe imbalances within households: it is also a measure of rising income inequality. That stated, many indicators are at unusual levels due to the historically low interest rate environment. Investment flows have been the principal driver of asset returns since the great recession, however, now that central bank interest rates in the majority of developed economies are near zero, it is difficult for investors to envisage a dramatic move into negative territory. Fear about an economic slowdown will see risk free government bond yields become more negative, but the longer-term driver of equity market return is no longer solely based on interest rate expectations. A more defensive approach to equities is likely to be seen if a global recession is immanent. Whether growth stocks prove resurgent or falter in the near-term, technology stocks will continue to gain relative to old economy companies, human ingenuity will continue to benefit mankind. Creative destruction, where inefficient enterprises are replaced by new efficient ones, is occurring despite attempts by central banks to slow its progress.

For the present I remain long the index, I continue to favour momentum over value, but, as was the case when I published – Macro Letter – No 93 back in March 2018, I am tempted to reduce exposure or switch to a value based approach, even at the risk of losing out, but then I remember the words of Ryan Shea in his article Artificial Stupidity: –

…investment success depends upon behaving like the rest of the crowd almost all of the time. Acting rational when everyone else is irrational is a losing trading strategy because market prices are determined by the collective interaction of all participants.

For the active portfolio manager, value factors may offer a better risk reward profile, but, given the individual stock volatility dispersion, a market neutral defensive factor model, along the lines proposed by AQR, may deliver the best risk adjusted return of all.

Macro Letter – No 93 – 23-03-2018

Stocks for the Long Run but not the short

  • In the long run stocks outperform bonds
  • For a decade stocks, bonds and real estate have risen in tandem
  • The risk of a substantial correction is high
  • Value-based equity investment is unfashionably enticing

The first part of the title of this Macro Letter is borrowed from an excellent book originally written in 1994. Among several observations made by the author, Jeremy Siegel, was the idea that stocks would at least keep pace with GDP growth or even exceed it at the national level. The data, which went back to the 19th Century, showed that stocks also outperformed bonds in the long-run. The price one has to pay for that outperformance is higher volatility than for bonds and occasional, possibly protracted, periods of under-performance or, if your portfolio is concentrated, the risk of default. This is not to say that bonds are exempt from default risk, notwithstanding the term ‘risk free rate’ which we associate with many government obligations. A diversified portfolio of stocks (and bonds) has been seen as the ideal investment approach ever since Markowitz promulgated the concept of modern portfolio theory.

Today, passive index tracking funds have swallowed a massive percentage of all the investment which flows into the stock market. Why? Because robust empirical data shows that it is almost impossible for active portfolio managers to consistently outperform their benchmark index in the long run once their higher fees have been factored in.

An interesting way of showing how indexation has propelled the stock market higher recently, regardless of valuation, is shown in this chart from Ben Hunt at Epsilon Theory – Three Body Problem. He uses it to show how the factor which is QE has trumped everything in its wake. I’ll allow Ben to explain:-

Here’s the impact of all that gravity on the Quality-of-Companies derivative investment strategy.

The green line below is the S&P 500 index. The white line below is a Quality Index sponsored by Deutsche Bank. They look at 1,000 global large cap companies and evaluate them for return on equity, return on invested capital, and accounting accruals … quantifiable proxies for the most common ways that investors think about quality. Because the goal is to isolate the Quality factor, the index is long in equal amounts the top 20% of measured  companies and short the bottom 20% (so market neutral), and has equal amounts invested long and short in the component sectors of the market (so sector neutral). The chart begins on March 9, 2009, when the Fed launched its first QE program.

Over the past eight and a half years, Quality has been absolutely useless as an investment derivative. You’ve made a grand total of not quite 3% on your investment, while the S&P 500 is up almost 300%.

Long term there are two strategies which have been shown to consistently improve risk adjusted return from the stock market, momentum (by which I mean trend following) and value (I refer you to Graham and Dodd). Last month the Managed Futures community, consisting primarily of momentum based strategies, had its worst month for 17 years. Value, as the chart above declares, has been out of favour since the great recession at the very least. Indiscriminate Momentum has been the star performer over the same period. The chart below uses a log scale and is adjusted for inflation:-

At the current level we are certainly sucking on ether in terms of the variance from trend. If the driver has been QE and QQE then the experiment have been unprecedented; a policy mistake is almost inevitable, as Central Banks endeavour to unwind their egregious largesse.

My good friend, and a former head of bond trading at Bankers Trust, wrote a recent essay on the subject of Federal Reserve policy in the new monetary era. He has kindly consented to allow me to quote some of his poignant observations, he starts by zooming out – the emphasis is mine:-

Recent debates regarding future monetary policy seem to focus on a degree of micro-economic precision no longer reliably available from the monthly data.  Arguments about minor changes in the yield curve or how many tightening moves will occur this year risk ignoring the dramatic adjustments in all major economic policies of the United States, not to mention the plausible array of international responses…

for the first time since the demise of Bear Stearns, et al; global sovereign bond markets will have to seek out a new assemblage of price-sensitive buyers…

Given that QE was a systematic purchase programme devoid of any judgement about relative or absolute value, the return of the price-sensitive buyer, is an important distinction. The author goes on to question how one can hope to model the current policy mix.

 …There is no confident means of modeling the interaction of residual QE, tax reform, fiscal pump-priming, and now aggressive tariffs. This Mnuchin concoction is designed to generate growth exceeding 3%.  If successful, the Fed’s inflation goal will finally be breached in a meaningful way…

…Classical economists will argue that higher global tariffs are contractionary; threatening the recession that boosts adrenaline levels among the passionate yield curve flattening crowd.  But they are also inflationary as they reduce global productivity and bolster input prices…

Contractionary and inflationary, in other words stagflationary. I wonder whether the current bevvy of dovish central bankers will ever switch their focus to price stability at the risk of destroying growth – and the inevitable collapsed in employment that would signify?

Hot on the heels of Wednesday’s rate hike, the author (who wrote the essay last week) goes on to discuss the market fixation with 25bp rate increases – an adage from my early days in the market was, ‘Rates go up by the lift and down by the stairs,’ there is no reason why the Fed shouldn’t be more pre-emptive, except for the damage it might do to their reputation if catastrophe (read recession) ensues. A glance at the 30yr T-Bond chart shows 3.25% as a level of critical support. Pointing to the dwindling of foreign currency reserves of other central banks as the effect of tariffs reduces their trade surplus with the US, not to mention the deficit funding needs of the current administration, Allan concludes:-

…Powell will hopefully resort to his own roots as a pragmatic investment banker rather than try to retool Yellenism.  He will have to be very creative to avoid abrupt shifts in liquidity preference.  I strongly advise a very open mind on Powell monetary policy.  From current levels, a substantial steepening of the yield curve is far more likely than material flattening, as all fiscal indicators point toward market-led higher bond yields.

What we witnessed in the stock market during February was a wake-up call. QE is being reversed in the US and what went up – stocks, bonds and real estate – is bound to come back down. Over the next decade it is unlikely that stocks can deliver the capital appreciation we have witnessed during the previous 10 years.

Whilst global stock market correlations have declined of late they remain high (see the chart below) the value based approach – which, as the Deutsche Bank index shows, has underwhelmed consistently for the past decade – may now offer a defensive alternative to exiting the stock market completely. This does not have to be Long/Short or Equity Market Neutral. One can still find good stocks even when overall market sentiment is dire.

For momentum investors the first problem with stocks is their relatively high correlation. A momentum based strategy may help if there is a dramatic sell-off, but if the markets move sideways, these strategies are liable to haemorrhage via a steady sequence of false signals, selling at the nadir of the trading range and buying at the zenith, as the overall market moves listlessly sideways. Value strategies generally fare better in this environment by purchasing the undervalued and selling the overvalued.

Conclusion

I was asked this week, why I am still not bearish on the stock market? The simple answer is because the market has yet to turn. ‘The market can remain irrational longer than I can remain solvent,’ is one of Keynes more enduring observations. Fundamental valuations suggest that stocks will underperform over the next decade because they are expensive today. This implies that a bear market may be nigh, but it does not guarantee it. Using a very long-term moving average one might not have exited the stock market since the 1980’s, every bear-market since then has been a mere corrective wave.

The amount of political capital tied up in the stock market is unparalleled. In a world or QE, fiat currencies, budget deficits and big government, it seems foolhardy to bite the hand which feeds. Stocks may well suffer from a sharp and substantial correction. Even if they don’t plummet like a stone they are likely to deliver underwhelming returns over the next decade, but I still believe they offer the best value in the long run. A tactical reduction in exposure may be warranted but be prepared to wait for a protracted period gaining little or nothing from your cash. Diversify into other asset classes but remember the degree to which the level of interest rates and liquidity may influence their prices. Unfashionable value investing remains a tempting alternative.
