Quant Mashup - Alpha Architect Using Firm Characteristics to Enhance Momentum Strategies [Alpha Architect]Research into the momentum factor continues to demonstrate its persistence and pervasiveness, including across factors. Recent papers have focused on trying to identify ways to improve the explanatory power and performance of momentum strategies. Prior research on Momentum The study “Momentum Has(...) An Analysis of “Graham’s Net-Nets: Outdated or Outstanding?” [Alpha Architect]In an earlier post we analyzed the prominent and often-cited study on “net-nets” conducted by Henry R. Oppenheimer from the Financial Analysts Journal (1986). In this post, we analyze the article “Graham’s Net-Nets: Outdated or Outstanding?” by James Montier. The objective of the article(...) A Framework for Creating Model Portfolios [Alpha Architect]Asset allocation is a very important decision for investors. Model portfolios are constructed with an optimized asset allocation process to help meet investor needs and preferences. The authors investigate the following research question: How does one construct a model portfolio? What are the(...) Alternative Investments - A Field Manual [Alpha Architect]It’s not a perfect world out there and often times alternative funds are mischaracterized, misused, and not put through a rigorous enough portfolio construction process. It’s my hope that I can forewarn you of the proverbial landmines and better prepare you to invest (or not invest) in the(...) Short-Duration Stock Anomaly: Risk or Mispricing [Alpha Architect]Some background on Bond duration: Duration measures bond’s price sensitivity to interest rates changes. It’s estimated based on the discounted expectations of the bond future cash flows and expressed in the number of years. The longer the duration, the higher the bond interest rate risk. (read(...) Quality: Independent attributes or a real factor? [Alpha Architect]The authors do a very nice survey on measures of quality found in the academic literature and in commercially available quality indexes. They examine seven quality categories including: profitability, earnings stability, capital structure, growth, accounting quality, payout/dilution and investment.(...) The Short Duration Premium [Alpha Architect]In my June 4, 2019 article “The Re-Death of Value, or Déjà Vu All Over?” I noted that one possible explanation for at least part of the poor performance of value stocks over the past decade has been the sharp fall in both the real interest rate (due to weak global growth) and unexpected(...) The Volatility Effect Revisited [Alpha Architect]One dirty little secret that has been hiding behind the curtains of finance for a long time, is that high-risk stocks do not have higher returns than low-risk stocks. Back in 1975 Haugen and Heins first recognized the low-risk anomaly: Our emperical efforts do not support the conventional hypothesis(...) Factor Investing from Concept to Implementation [Alpha Architect]There is a substantial debate on the topic of factor investing and whether or not the “backtested” excess returns are actually achievable in practice. Much of the research on the topic suggests that practitioners in the field are unable to capture any of the so-called “factor premiums”. For(...) The Failure of Value Investing explained [Alpha Architect]It’s no secret that value has had a bad bout of performance in recent memory. This underperformance has been thoroughly examined by multiple research teams and we’ve done some of our own work on the subject. We’ve also done in-depth rebuttals to “value investing is dead” articles in the(...) Value: Don't Call it a Comeback, it's Been Here for Years [Alpha Architect]Value and Momentum each had back to back extreme returns (five sigma) days on Monday, September 9th and Tuesday, September 10th. The Dow Jones Thematic Market Neutral Value Index (“Value”) started the week up 3.45%, its best day since inception on December 31st, 2001. The Value Index followed(...)

We are a little over 3 weeks away from March for the Fallen (#MFTF). NOTE: There is a monster training event occurring simultaneously to MFTF this year so be prepared to dodge humvees and watch out for stray(...) An Analysis of “Benjamin Graham’s Net Current Asset Values: A Performance Update” [Alpha Architect]The study examined the performance of securities that were trading at no more than two-thirds of its Net Current Asset Value (“NAV”) during the 1970-82 period in the US Net nets, on a gross basis, more than tripled the returns of the market (as measured by the S&P 500 TR) Net nets, on a net(...) Crisis proof your portfolio: part 2/2 [Alpha Architect]This is part 2 (part one is here) of an excellent article that examines the feasibility and effectiveness of protecting equity portfolios using traditional passive means and more contemporary active strategies. It is jam-packed with information and analysis that is best consumed in two parts;(...) Can We Explain the Low Volatility Anomaly? [Alpha Architect]One of the big problems for the first formal asset pricing model developed by financial economists, the CAPM, was that it predicts a positive relation between risk and return. But empirical studies have found the actual relation to be flat, or even negative. Over the last 50 years, the most(...) Social Media, News Based Sentiment, and Market Timing [Alpha Architect]With a growing availability of filtered (news) and unfiltered (social media) information, the author investigates the following question: Do news or social media contain any information that is of relevance for investment decision making and if so are the two sources are complementary or(...) Crisis Proof Your Portfolio: part 1/2 [Alpha Architect]This is a unique article in that it directly assesses the feasibility and effectiveness of protecting equity portfolios using traditional passive means and more contemporary active strategies. It is jam-packed with information and analysis that is best consumed in two parts; however, a good summary(...) The Variance Risk Premium is Pervasive [Alpha Architect]The variance risk premium (VRP) refers to the fact that, over time, the option-implied volatility has tended to exceed the realized volatility of the same underlying asset. This has created a profit opportunity for volatility sellers—those willing to write volatility insurance options, collect the(...) Do Most Individual Stocks Outperform Cash? No. [Alpha Architect]I’d argue that a typical investor believes the following–In the past and over the long run, stocks outperformed bonds.(1) However, as highlighted here, an academic paper last year shows that the majority of individual U.S. stocks actually lost compared to Treasury Bills (i.e. the return to(...) Betting Against Beta (BAB) Construction [Alpha Architect]One of the more popular equity strategies over the past decade is low volatility investing. Simply put, this is a systematic strategy that invests in stocks with lower volatility, either measured by Beta or standard deviation. Why? Well, the low-beta anomaly is the fact that in the past, academics(...) No Skill? Well, Active Share Won't Save You! [Alpha Architect]What are the research questions? This paper is the first to examine the impact of including an active share target into the mean-variance optimization process of constructing portfolios. They use the Ceria and Stubbs (2006) approach to robust portfolio optimization as methodology. Monte Carlo(...) Can Low Vol Strategies Be Improved [Alpha Architect]My Advisor Perspective article of June 17, 2019 discussed the regime shifting nature of the low volatility anomaly—low volatility stocks have outperformed high volatility stocks, providing both higher returns while experiencing lower volatility. For example, in his 2012 paper, “Enhancing a(...) Compound Your Knowledge Ep 18: Size, Mom, Sell-Offs, & R Code [Alpha Architect]In this week’s post, we discuss four articles. The size, written by the folks at AQR, is titled “Fact, Fiction, and the Size Effect” and is a deep dive into the Size effect–I highly recommend everyone read the underlying paper as well. The second article examines the baseline historical(...) Value Investing & Concentration [Alpha Architect]As many investors have experienced, Value investing has underperformed for some time now. For the period following the Global Financial Crisis, Value investing (in general) has underperformed (1) the market and (2) Growth stocks. So while the past decade has been rough for Value investors, it can be(...) Strategies to Reduce Crash Risk in Stocks [Alpha Architect]Because equities are much riskier than high-quality bonds, the vast majority of the risk of a conventional 60 percent equity/40 percent bond portfolio is equity risk. Here’s the simple math demonstrating the point. Well-diversified equity portfolios have volatility of about 20 percent, and(...) Pathetic Protection via Protective Puts [Alpha Architect]Investors would like to maximize upside participation while mitigating losses. This preference is at the base of the growth of the liquid insurance market in the form of equity index options. The author investigates the following research question: Are protective put options an effective tail hedge?(...) Enhancing the Performance of Momentum Strategies [Alpha Architect]In “Your Complete Guide to Factor-Based Investing,” Andy Berkin and I presented the evidence demonstrating that momentum, both cross-sectional (or relative) momentum and time-series (or absolute, trend following) momentum, not only increases the explanatory power of asset pricing models while(...) Momentum, Quality, and R Code [Alpha Architect]Welcome to the first installment of Reproducible Finance by way of Alpha Architect. For the uninitiated, this series is a bit different than the other stuff on AA – we’ll focus on writing clean, reproducible code, mostly R (but some python too), applied to different ideas from the world of(...) Market Sell-off Analysis: Baseline Historical Facts [Alpha Architect]We often hear that the market is 5% off its highs or that it is down 5% from the high of the year. This alone does not tell us much. The questions I want to answer are as follows: “How often does that 5% loss become a 10% loss? Or worse yet — a 20% loss?” In other words, what are the(...) Fact, Fiction, and the Size Effect [Alpha Architect]The size effect is the phenomenon in which small stocks (i.e., those with lower market capitalizations), on average, outperform large stocks (i.e., those with higher market caps) over time. The size effect was first documented by several academic papers in the early 1980s ( Banz, 1981). However, it(...) Debunking myths about stock buybacks [Alpha Architect]What are the research questions? The authors present 4 MYTHs regarding stock buybacks popular in the financial press. MYTH 1: Companies are self-liquidating using share repurchases at a historically high rate. MYTH 2: Share repurchases have come at the expense of profitable investment. MYTH 3: The(...) Trend Following: The Epitome of No Pain, No Gain [Alpha Architect]One of the recurring themes we see in our research is the concept of “no pain; no gain.” Or as Corey Hoffstein says, “No pain, no premium.” Cliff Asness may put it best when he says that some strategies require that you hold on to them “like grim death.” Bottom line: nothing is easy in(...) Large-Cap Price-to-Book Investing: What is Dead May Never Die [Alpha Architect]In the great book and series Game of Thrones, the inhabitants of the Iron Islands have a saying “What is Dead May Never Die” which is to be replied with “But rises again harder and stronger.” I am reminded of this saying as more and more market commentators and practitioners declare that(...) Factor Investing Research On Steriods [Alpha Architect]What are the research questions? Do the most prominent long/short factors — value, momentum, carry, and defensive — survive out of sample? Can long/short factors be timed? What are the Academic Insights? YES. All of the factors exist out of sample, albeit their magnitudes are generally muted.(1)(...) Value Factor Valuations Over Time: US and Developed [Alpha Architect]We built a simple tool recently to review so-called value spreads over time. (1) This tool maps out the median valuations for the top decile and bottom decile “cheap stock” portfolios (as measured by EBIT/TEV). Why might this be useful? This tool allows one to identify the “valuation” spread(...) The Cross-Section of Emerging Market Stock Returns [Alpha Architect]As a non-academic finance person, I was never really exposed to academic research until I started working on articles for Alpha Architect. Fortunately (or unfortunately, depending on your perspective), I am now very familiar with the so-called “cross-section of expected returns” debates.(...) The Re-Death of Value, or Déjà Vu All Over? [Alpha Architect]The underperformance of value stocks over the past 10 years has received much attention from the financial media and led at least some investors to conclude that value investing is dead. From 2009 through March 2019, while the S&P 500 Index returned 14.2 percent per annum (total cumulative(...) Is factor momentum really everywhere? [Alpha Architect]The research presented here covers the largest number of factors (65) tested in the academic literature. The most robust and well-cited factors appear in the list of data items, available since the 1960s. A notable exclusion is the IBES dataset, which is available only in the 1980s. Is there(...) Skewness Effect in Commodities [Alpha Architect]Nothing lasts forever and this definitely stands true for equity markets where volatility can explode and investors can lose a lot of money very quickly. Because of equity market volatility investors often seek so-called “crisis alpha” instruments, or assets that tend to go up when equity(...) News Sentiment and Bonds [Alpha Architect]Academic literature has documented a news sentiment effect on equities ( here and here ). The authors investigate the following research question: Does the sentiment derived from media content impact bond market investors? What are the Academic Insights? By studying the sentiment extracted from(...) Volatility Targeting Improves Risk-Adjusted Returns [Alpha Architect]There’s a large body of research, including the 2017 study “Tail Risk Mitigation with Managed Volatility Strategies” by Anna Dreyer and Stefan Hubrich, that demonstrates that, while past returns do not predict future returns, past volatility largely predicts future near-term(...) Volatility Anomalies: IVOL and Vol-of-Vol [Alpha Architect]Two of the more interesting puzzles in finance are related to volatility—stocks with greater idiosyncratic volatility (IVOL) have produced lower returns and stocks with high uncertainty about risk, as measured by the volatility of expected volatility (vol-of-vol), underperform stocks with low(...) Short Selling + Insider Selling = Profitable Strategy? [Alpha Architect]What are the research questions? This study uses a long and comprehensive time series covering 1977-2014, with just under 180,000 quarterly observations for trades of short sellers and demand for shares by corporate insiders. (see here for a related paper we covered recently that talks about(...) Buying Stocks Trading Above 10x Sales-A Good Idea? [Alpha Architect]Early last week, Meb Faber included me on a conversation on buying stocks trading at 10x their company’s revenue (sales). Is this a good idea and how did it do in the past? Given that most “known” factors have underperformed over the past 10 years, I was interested in seeing if a somewhat(...) Democratize Quant 2019 Recap [Alpha Architect]We did it. We democratized quant for one more year. Last year, we suffered through a 50% drawdown in attendance due to a perfectly timed snow storm. This year the weather cooperated with us and we were able to get everyone there. Full access to presentation videos and the accompanying slides (when(...) Tax-Managed Factor Strategies [Alpha Architect]The authors decompose strategy returns into factor alpha, tax alpha, and residual return for 6 tax-managed versus and 6 tax-indifferent factor strategies and for one indexing strategy. In contrast to other studies, where the impact of starting date dependence is eliminated, this research generates a(...) Compound Your Knowledge Ep. 11: ETFs, Manager Wealth, TLH, Value [Alpha Architect]In this week’s episode, we cover four articles published on our site. The first article, written by Ryan, examines the growth in assets of ETFs and Mutual Funds. The second article, summarized by Elisabetta, examines the performance of funds by differentiating the fund’s manager on his/her(...) Deep Dive into the Value Factor [Alpha Architect]The financial equivalent of the famous Miller Lite, “tastes great, less filling” debate is the debate between traditional financial economics which uses risk theories to explain asset pricing and the newer behavioral finance field that uses human behavior to provide the explanations.(...) Compound Your Knowledge Episode 10: Factor Investing & Hedge Fund Performance [Alpha Architect]In this week’s video, we discuss three posts. The first post discusses the new index analysis section on our site. The second post, written by Tommi, uses Hedge Funds’ past performance to identify if one can predict future Hedge Fund performance. The last post discusses Wes’ video examining an(...) Buyer Beware: The Reality of Tax-Loss Harvesting Benefits [Alpha Architect]Tax loss harvesting is widely promoted, but we think the benefits are generally misunderstood and often overstated.(1) • The benefits of loss harvesting arise from tax deferral, similar to the benefits of saving in a retirement account. • The benefits of tax deferral rise and fall with expected(...)
