  • Treasury Bonds: Buy and Hold or Trend Follow? [Alpha Architect]

    We were recently asked what we thought about bonds as an investment. A lot of this was inspired by my comments on bonds via a discussion on how I personally invest. Ill repost what I said on bonds below: What are your thoughts on bonds and commodities? In general, Im not a fan of corporate bonds as a buy-and-hold asset class. Outside of treasury bonds, most bonds earn lower returns than
  • What Drives Momentum and Reversal? [Alpha Architect]

    What are the research questions? Theories abound in the financial literature explaining the drivers of momentum and reversal in one way or another. Not surprisingly, most portray the role of public and private information as key to the underlying relationships and weigh the type of information differently. For example, if the driver of momentum is a fundamental underreaction to public information,
  • Revisiting the Performance of TAA ETFs [Factor Research]

    There has been a boom in launching tactical asset allocation ETFs However, the recent track record of these has been poor Declining stock and bond markets have created a challenging environment for these INTRODUCTION Most investment strategies become popular through short rather than long periods, simply because no strategy works all the time. The longer the track record, the more explanation is
  • Research Review | 5 August 2022 | Multi-Factor Strategies [Capital Spectator]

    Combining Factors Christoph Reschenhofer (Vienna University of Economics and Business) July 2022 While the academic literature primarily investigates factor exposures based on covariances (i.e. beta exposure), most practitioners apply characteristics-based scorings to obtain factor portfolios. It hereby remains largely unexplored how firm-level characteristics can be combined to obtain optimal
  • Crashes in safe asset markets [SR SV]

    A new theoretical paper illustrates the logic behind runs and crashes in modern safe asset markets. Safe assets are characterized by stable value and high liquidity. In times of distress flight for safety increases demand for these assets, while dash for cash increases supply. However, these two are not generally in balance. If the need for liquidity is expected to dominate and dealer

  • Avoiding Momentum Crashes [Alpha Architect]

    In our book Your Complete Guide to Factor-Based Investing, Andrew Berkin and I presented the evidence demonstrating that momentum, both cross-sectional (CSMOM) and time-series (TSMOM), has provided a premium that has been found to be persistent across time and economic regimes, pervasive around the globe and across sectors and asset classes (stocks, bonds, commodities, and currencies),

  • Avoiding Volatile Trades [Alvarez Quant Trading]

    In my last blog post, Using Historical Volatility for Parameter Adjustment, I tested using historical volatility to determine trade rules. While reading the July 2022 Technical Analysis of Stocks & Commodities, I came across an article, Is It Too Volatile To Trade? by Perry Kaufman. I always like his work so I was interested to see what he had to say. He uses standard deviation from the
  • Trend Following Says Commodities…But Nothing Else! [Alpha Architect]

    Just recently we posted the trend-following weights for our Robust Asset Allocation model. Something interesting happened the model suggested zero exposure to every asset, except commodities(1) source: https://alphaarchitect.com/indexes/trend/#trendasset My knee-jerk reaction was, Wow, never seen that before. But as is the case with all emotional reactions, it is important to not lean on
  • How heavy tails destabilize Markowitz portfolio selection [Artifact Research]

    This is the forth and final post of a short series of posts on extreme events in financial time series. In the first post, we have introduced power-law theory to describe and extrapolate the chance of extreme price movements of the S&P500 index.

  • The Effective Number of Bets: Measuring Portfolio Diversification [Portfolio Optimizer]

    Many different measures of portfolio diversification have been developed in the financial literature, from asset weights-based diversification measures like the Herfindahl Index1 to risk-based diversification measures like the Diversification Ratio of Choueifaty and Coignard2 to other more complex diversification measures. Because each of these measures usually provides information about a

  • Do Stocks Efficiently Predict Recessions? [Alpha Architect]

    What are the Research Questions? There is abundant literature on the relationship between the business cycle and future stock returns. The traditional view is that stocks are rationally priced to immediately reflect investors expectations about future economic activity and that expected excess returns on stocks are positive, vary over time, and display counter-cyclical behavior. The author asks

  • Practical Implementation of Strategic Allocation Bets with Black-Litterman [DileQuante]

    As a portfolio manager or as a portfolio construction analyst, the most usual way to manage a fund is to elaborate a Strategic Asset Allocation (a.k.a. SAA), that is reviewed on a mid or low frequency, on which PM or researchers add their tactical views, i.e. a Tactical Asset Allocation (a.k.a. TAA), which can be refreshed on a higher frequency. The SAA reflects the long term view of

  • Machine learning in macro [Cuemacro]

    There are buzzwords and there are buzzwords. The buzziest (if that indeed is a word) of buzzwords in technology is that of machine learning, whether its using machine learning to improve image recognition, natural language processing etc. Although, Ive got to admit, theres still a long way to go I still repeatedly get advised to apply for FX roles on LinkedIn, which are actually
  • The Expected Returns to ESG-Excluded Stocks [Alpha Architect]

    As Sam Adams and I explained in our new book, Your Essential Guide to Sustainable Investing, while sustainable investing continues to gain in popularity, economic theory suggests that if a large enough proportion of investors choose to favor companies with high sustainability ratings (green businesses) and avoid those with low sustainability ratings (brown or sin businesses), the favored

  • Copulas and trading strategies [SR SV]

    Reliance on linear correlation coefficients and joint normal distribution of returns in multi-asset trading strategies can be badly misleading. Such conventions often overestimate diversification benefits and underestimate drawdowns in times of market stress. Copulas can describe the joint distribution of multiple returns or price series more realistically. They separate the modelling of
  • Relative Sentiment and Machine Learning for Tactical Asset Allocation: Out-of-Sample Results [Alpha Architect]

    In our last installment, we reviewed the performanceacross four regionsof a machine-learning-based Sentix relative sentiment model for tactical asset allocation. The regions included: the USA, Europe, Japan, and Asia ex-Japan (referred to as USA, EUR, JPN, and AEJ, respectively, in the charts and tables below). The SSRN paper (written in October 2019) that introduced the model showed results
  • Short Sellers Are Informed Investors [Alpha Architect]

    Short sellers play a valuable role in keeping market prices efficient by preventing overpricing and the formation of price bubbles in financial markets. Market efficiency is important because an efficient market allocates capital efficiently. If short sellers were inhibited from expressing their views on valuations, securities prices could become overvalued and excess capital would be allocated to

  • Slava Ukraini! Latest from Quantocracy contributor in Ukraine: Trading Signals In VIX Futures [Only VIX]

    Marco Avellaneda has contributed tremendously to financial mathematics, and to volatility trading in particular, has passed away earlier this year. Here I will review one of his last papers on trading VIX futures. I think most readers of this blog have modeled VIX futures understand both the risks and potential profitability of roll strategies, and the most difficult part is balancing the two. VIX
  • Correlation Matrix Stress Testing: Shrinkage Toward the Lower and Upper Bounds of a Correlation Matrix [Portfolio Optimizer]

    I previously described on this blog an intuitive way of performing stress tests on a correlation matrix, which consists in shrinking a baseline correlation matrix toward an equicorrelation matrix12. A limitation of this method, though, is that it alters all the correlation coefficients of the baseline correlation matrix, so that it is for example impossible to stress only the correlation between
  • Evaluating Inflation Hedges [Factor Research]

  • Can We Measure Inflation with Twitter [Alpha Architect]

    Twitter is an interesting dataset for researchers interested in consumer beliefs. (200 million monthly active users worldwide (Elon Musk may disagree!) and about 10 million active users in Italy in 2019 (AGCOM 2020)). Inflation expectations are at the heart of any consumption and investment decision of households and firms in the economy. There are two commonly used sources of inflation

  • Effective Allocation Measure with Entropy Application for Correlated Crypto Assets [Quant at Risk]

    Surprisingly, in the literature there are only few effective formulae for asset allocation. They are based on the asset types and, in theory, they should define investors risk appetite. For instance, a large exposure in stocks should define aggressive investment style in comparison to investing in bond market. While, in general, this approach is true and intuitive, it lacks a quantitative
  • Momentum Everywhere, Including in Factors [Alpha Architect]

    Empirical research, including the 2017 paper A Century of Evidence on Trend-Following Investing, has found momentum to be a persistent and pervasive factor in returns of not only stocks but other asset classes as well, including bonds, commodities, and currencies. Recent empirical research on the momentum factor, including the 2018 studies Factor Momentum Everywhere (Summary) and Is
