Has Risk Parity Jumped The Shark? Asness Says No

By DailyAlts Staff According to AQR’s Cliff Asness, anyone who thinks risk parity caused the massive selloff in August has gone “all tinfoil-hat”. A better argument against risk parity, Mr. Asness concedes, is the fact that it has underperformed over the past several years. But is this underperformance a result of the strategy having jumped the proverbial shark ? Or is it simply a bad run to be expected with any strategy? Not surprisingly, Mr. Asness thinks it’s probably the latter, and this is the view he articulates in ” Putting Parity Performance into Perspective ,” the alliterative latest in his Cliff’s Perspectives series of white papers. Risk Parity Basics Mr. Asness takes the first few paragraphs of the paper to refresh readers on the basics of risk parity : “an alternative long-term strategic asset allocation” used to “diversify a more traditional equity-dominated allocation.” Rather than weighting holdings by market cap, risk parity weights them based on their anticipated contribution to overall portfolio risk – and in order to achieve the right mix, this means leverage is used to ramp up low-risk fixed-income holdings. From Cliff’s perspective, risk parity offers a “real but modest long-term edge” over traditional approaches because many investors are “too averse” to applying leverage. Risk parity is often described as an “all-weather” solution, succeeding regardless of the broad market’s ups and downs, and Mr. Asness believes this is true – on average . Unfortunately, we’re not living in “average” times, and as a result, risk parity has underperformed since 2009. Longer-Term Returns It’s impossible to do true risk parity back-testing as far back as 1947, so AQR uses “Simple Risk Parity” for historical analysis. The firm’s findings indicate that the “real but modest long-term edge” that risk parity enjoys over indexing really adds up over time. This is evident in the image below, which charts the cumulative excess return of Simple Risk Parity over the past 68 years: The image above shows Simple Risk Parity’s excess returns above cash. The image below shows its excess return above a “60/40” stock/bond portfolio. This helps put the strategy’s underperformance since 2009 into longer-term historical perspective: Forward Outlook Risk parity is designed to diversify away from equity risk. Instead of adding equities to a portfolio in pursuit of desired returns, risk-parity strategies favor using leverage to ramp up fixed-income risk. With equities outperforming for the past six years, it should be no surprise that risk parity has underperformed. Moreover, risk-parity strategies have also been slammed by the bear market in commodities, whereas “60/40” portfolios don’t even have direct exposure to that asset class. But do these facts mean that risk parity’s happy days are over? Not in Cliff Asness’s view. He suggests that the recent underperformance is of the sort that’s to be expected with long-term strategies, and adds that periods of underperformance are often followed by periods of outperformance. The problem, as he sees it, is that short-term periods of poor performance can feel awfully long – and this can lead to investors bailing at the wrong time. If traders have tactical reasons for wanting to allocate away from risk parity, that’s one thing – but selling because of painful results that should be expected from time to time is unwise, in Asness’s view, even if resisting the urge to do so is “one of the hardest but most important parts” of an investment professional’s job.

Does The Size Premium Apply To Countries?

Summary A size premium has been extensively documented in financial literature and some studies have reported a size premium at the country level as well. Portfolios constructed under max-country weight strategies have achieved higher returns and better risk-adjusted performance as measured by Sharpe ratios, albeit with higher volatilities, compared to the benchmark. Max-country weight strategy suggests a potential robust portfolio construction methodology that could provide diversification benefits and improve the portfolio’s risk-adjusted performance compared to the benchmark. Since 1981, the “size premium,” or the tendency for smaller-capitalization securities to outperform their larger-cap counterparts, has been extensively documented in financial literature in the United States. Some studies have extended this research and reported that the size effect applies for country indices as well. Gerstein Fisher conducted research on the relationship between aggregate country equity market capitalizations and country-level market index returns and explored how a market-cap weighted international portfolio can be improved by limiting the weight of larger countries, such as Japan and the United Kingdom, and redistributing weights to smaller countries. For our study, we examined a capitalization-weighted basket of developed-market country indices (excluding the US) that resembles the MSCI EAFE Index. We used this index as our benchmark, and have reported country component weights of this index in the right-most column of Exhibit 1. We then limited the maximum weight of any one country in the portfolio (ranging from a 10% cap to 15%) and re-distributed that weight to all other countries according to their market capitalizations. If, after the re-allocation, any country exceeded the maximum portfolio weight, we repeated the process and re-allocated the additional weights. Exhibit 1, which provides the average exposures of each country in the various country-capped portfolios, and the benchmark over the sample period from January 1997 to July 2015 shows that this process generally reduced the weight of the two largest countries, Japan and the United Kingdom, and added the most weight to the larger of the smaller countries – France, Germany, Switzerland and Australia – resulting in a more even distribution of country weights in the modified portfolio. (click to enlarge) Exhibit 2 reports the performance of our strategy on a cumulative and annualized basis relative to the benchmark; Exhibit 3 shows results on a cumulative basis over time. As shown in both of these exhibits, all of the capped approaches have achieved modestly better cumulative and annualized returns compared to the benchmark over the period from January 1997 to July 2015. Note that this outperformance is achieved with higher volatilities (as measured by annualized standard deviations). The highest volatility (18.45%) is observed for the portfolio applying a 10% country-weight limit and the lowest (17.92%) for the portfolio applying a 15% country-weight limit, compared to 17.14% for the benchmark. Despite the higher volatilities, all capped approaches delivered better risk-adjusted performance as measured by Sharpe ratios (ranging from 0.345 to 0.373), compared to the Sharpe ratio of the benchmark (0.304). (click to enlarge) (click to enlarge) Without further research, we can only speculate about what causes the “small country effect.” The higher return may be explained by the tilts towards the value factor: we have assigned greater-than-market weights to stocks with high fundamentals relative to price and less-than-market weights to stocks with low fundamentals relative to price at the country level in the form of country max limits since smaller countries tend to have higher growth potential and less expensive equity markets. For example, Japan, a country with a relatively low dividend yield, sees its weight in the country-capped portfolios decrease by a range of 9% to 14% with respect to the benchmark. There is a trade-off associated with tilting toward small countries, however, by using this technique. The increased volatilities indicate that small markets are riskier than larger ones. But the increase in volatility is limited since by applying a max-country weight strategy we limit the portfolio’s exposure to any single country, thus enhancing portfolio diversification and lowering concentration risk. Overall, a max-country weight strategy suggests a potential robust portfolio construction methodology that could improve the portfolio’s risk-adjusted performance, as shown by increased Sharpe ratios compared to the benchmark. For more detail and the full results of our study, we invite you to read our research paper, Country Size Premiums and Global Equity Portfolio Structure . Conclusion Our research points to a possible methodology to better structure a multi-country portfolio: varying allocations to different countries based on their equity market capitalizations. As we show, re-distributing some of the weight of larger countries to smaller countries can improve an international stock portfolio’s risk-adjusted performance.

No, Jesse Had It Right: Owning Stocks Today Has An Unattractive Risk/Reward Profile

My rebuttal to Terrier’s rebuttal. Terrier seems to believe that timing the market is not possible, but beating the market through stock picking is very much possible. Many bulls look at one market over one long stretch of time and believe they’re all clear for 10+ year periods… nope. Terrier Investing posted a rebuttal this morning to Jesse Felder’s original piece : “Owning Stocks Today is Risking Dollars to Make Pennies.” Terrier makes three points in his rebuttal. To quote: Well, according to Jesse, it means stocks are so wildly overvalued that your potential return over the next ten years is miniscule, and your potential downside is massive. I posit this is: A) alarmist and statistically inaccurate; B) overly narrow in its definition of risk; and C) treats “stocks” as some monolithic entity” Each of Terrier’s points are problematic; I’ll handle them one by one. Before I do, however, let me say that Terrier makes many sensible claims in his rebuttal. I dispute his line of reasoning here, mainly because he uses three arguments that I think undergird many bulls’ logic, whether they realize it or not. Someone like Terrier who explicitly makes assumptions is in my view on much firmer soil than the many bulls who are implicitly making the identical assumptions. If Terrier sees reason to modify his explicit a priori, he can. Bulls that are actually sheep have no such explicit framework against which they can base a reasonable shift to their investment thesis. With those disclaimers out of the way, I will now address the problems that I see with Terrier’s arguments. A) Alarmist and statistically inaccurate (sorry to quote so much of Terrier’s piece, but I want to address what he DID say, not what he didn’t): What is the actual likelihood of stocks resulting in a significantly negative 10-year return? Here’s a link to a nice document providing this data from 1926 through 2013 in both tabular and graphical format. Summarily, there were only a very few rolling 10-year periods when investing in the S&P 500 would have resulted in losses in nominal terms. Specifically, you would have had to invest right before the Great Depression or in the late 1990s – two of the larger bubbles of all time. Looking at one market over one stretch of time, even a long stretch, does not give you a statistically robust sense of what that market can do over any 7-15 year timeframe. I’ll grant you that it’s better than a sharp stick in the eye, but the data can easily mislead. I wonder what the German stock market would have looked like over the first half of the twentieth century. After enduring two world wars, a bout of hyperinflation, and political dismemberment, I don’t believe that German stocks performed too well over that meaningfully long timeframe. The German stock market was at the time (and still is) a well-developed market. I wonder what fraction of those 10-year periods had sizeable losses. Whoever said that can’t be us? From an Investopedia article on history of stocks and bonds: At the same time, many other economies suffered great losses. For example, according to Phillipe Jorion and William N. Goetzmann in their article “Global Stock Markets In The Twentieth Century” (1999), the Japanese stock market saw a 95% decline in real returns between 1944 and 1949. The German market also suffered devastating losses. In this context, the U.S. market’s success seems to be an exception, which the previous lack of data for other countries may have obscured. (emphasis added) Japan 1986 to present?…let’s not look there I’m guessing. (click to enlarge) How about the US stock market from 1891-1974? There were many poor return stretches over that time frame, especially when viewed on a real return basis. That’s a long stretch in our own market; how do the total return statistics bear out? While I’ll grant that the percentage of positive ten-year returns would likely still be high, the final results would be substantially more lackluster, particularly for investors who did not reinvest all of the dividends over the entire horizon with no tax implications. In fact, depending on your starting and ending points, you can find periods of negative real returns over a fifty-year time frame if you don’t include complete dividend reinvestment over the entire 50+ horizon. To see that this is the case, check out Political Calculation’s S&P calculator . Enter some periods that end in 1974 or 1983 for instance. I’m not trying to cherry pick here; I am demonstrating that there certainly are periods for even the longest of practical time horizons where equity returns are quite unattractive. There are two other, larger reasons why past may not be prologue for S&P returns. And I’ll address these points alongside Terrier’s point B: B: Risk as volatility, not as permanent loss of capital Moreover, there is more than one definition of “risking dollars” – assuming you have a ten-year or greater time horizon and need to invest to fund long-term liabilities (kids’ college funds, retirement, etc.), then earning near-zero returns by investing exclusively in bonds is just as much of a risk as potential volatility from investing in stocks. Risk, in this context, means you won’t meet your financial goals – and if you don’t invest in any stocks, it’s very hard to see how you will generate sufficient returns with yields on fixed income where they are. Some clarification here first. Terrier goes on to say that he believes that the market as a whole is on the expensive side (which leads to his point C), so he’s not some brainless stock market cheerleader. To that same end, Felder never explicitly says that nobody should have any equity exposure. (As for me, I have plenty of equity exposure: I’m short SPX.) Terrier’s second point essentially makes an assumption: risk as volatility vs. risk as probability of permanent capital loss. If risk is merely volatility – stocks whipping around for short and maybe even violent bursts, only to recover over a reasonably quick timeframe and make new highs – then I believe that he is correct. In his defense, he doesn’t suggest going “all-in” on equities, and even recommends having a decent cash pile. The issue is that Terrier’s problematic analysis from his first point (stocks rarely have negative nominal 10-year returns) leads him to the next conclusion that equity risk is actually only volatility, not capital impairment. This is where Terrier and I truly part company. Many long-only investors believe that strong long-run SPX returns happen mostly as a simple function of time; they’re somehow owed these returns for weathering volatility. I find it amusing that these same long-only bulls don’t feel like Brazilian investors are owed strong long-run returns, or that Greek or Russian or Japanese or South African equity investors are owed long-run returns. This amounts to a personally dangerous form of financial jingoism. Let me make it clear: IF sustained poor equity returns can happen to Brazil (the world’s seventh largest economy), then they can happen for the US. See, investors today aren’t looking at the Greek market and shrugging it off as a temporary bout of volatility. Ditto the other markets mentioned above. Investors correctly see these declines for what they are: semi-permanent capital loss. That is to say that even a strong bounce and even full dividend reinvestment will not bring a buy-and-hold index investor who purchased in, say 2010, back to even for years to come. Bears like Felder and myself believe that S&P balance sheets, investor margin positioning, GDP growth trends, and equity valuations in light of a slowing global economy put the S&P 500 at risk of a vigorous fall that will NOT be recovered anytime soon. (click to enlarge) (click to enlarge) Source: FactSet Why should we expect S&P returns that approximate history when a) GDP growth (global or US) is nothing like what it has been in the past, b) corporate balance sheets are not very healthy and c) valuations for the broad market are MORE expensive for almost every decile than at the March 2000 peak? To conclude, Terrier states: Risk, in this context, means you won’t meet your financial goals – and if you don’t invest in any stocks, it’s very hard to see how you will generate sufficient returns with yields on fixed income where they are. Well, what if the S&P falls – a LOT – and does not recover? Meeting one’s financial goals goes from being difficult to completely impossible. I believe such an outcome needs to be given a very meaningful weight. Terrier’s last point is that we don’t have a stock market, but a market of stocks: Finally, point C: I think it’s unfair to treat “stocks” as a monolithic entity – as if you either own the S&P 500 (NYSEARCA: SPY ) or you do not, and there’s no other alternative. Even if you believe the market as a whole is overvalued, like I do, that doesn’t mean every single component of the market is overvalued. Terrier goes on to say that one can do research and find a basket of stocks that will beat the market. Which is basically saying that Terrier doesn’t believe that investors can beat the market via market timing (“Not owning the market is risking dollars to make pennies”), but that they can beat the market through security selection. I completely disagree. Look at all the “smart beta” ETFs and actively managed mutual funds that are essentially continuously fully invested. How many of those pros beat the market? Not too many. I’m not saying that it cannot be done, but I see no reason – whatsoever – why market outperformance through the security selection channel is so much easier to consistently achieve than market outperformance via the market timing channel. But my objection to Terrier’s point C goes well beyond this first point: In 2013, the most heavily-shorted stocks were some of the best performers . It tends to be sophisticated investors that short companies. Full disclosure: I have never in my life shorted an individual name, and so I claim absolutely no expertise on this process. These securities specialists had their you-know-what’s handed to them, because it was a bad idea to be short any stock in the S&P during 2013. Similarly, it was a bad idea to be long any stock in the S&P between March 2008-March 2009. When “the market” gets crazy (up or down), security selection absolutely will not save you… period. At that point, the macro takes over, and the micro gets buried. That doesn’t mean that security selection cannot help you (assuming that you can in fact do it AND stick to your discipline): better to lose 33% than 40% or 60% instead of 75%… but you still won’t be happy with your strongly negative returns. In conclusion, Terrier states in his point A (in context of negative 10-year returns): Specifically, you would have had to invest right before the Great Depression or in the late 1990s – two of the larger bubbles of all time. My stance, and I believe Felder’s as well (though I’ll let him speak for himself), is precisely that today’s market IS one of those great bubbles. James Paulsen of Wells Capital Management produced the chart below to compare P/Es of the S&P for each 5-percentile increment for year-end 2014 vs. June 2000. The overvaluation of the broad markets is far more severe than it was in 2000, and so when the bottom falls out, there may not be too many great places to hide from the merciless reaping that ensues. Permanent capital impairment from any and all long US equity exposure needs to be treated not as a fringe case, but as THE base case. In that world, long investors really indeed are risking dollars that they won’t recover for years in order to pick up those juicy 3-5% yields or hope for the continuation of a stretched and tired bull.
