  • Attack of the Clone: Lessons from Replicating Long/Short Equity [Flirting with Models]

    In this commentary we attempt to identify the sources of performance in long/short equity strategies. Using Kalman Filtering, we attempt to replicate the Credit Suisse Long/Short Liquid Index with a set of common factors designed to capture equity beta, regional, and style tilts. We find that as a category, long/short equity managers make significant changes to their equity beta and regional tilts
  • Statistical Arbitrage in the US [Factor Research]

  • Constructing Long-Only Multifactor Strategies: Portfolio Blending vs. Signal Blending [Alpha Architect]

    The heightened interest in factor investing has been accompanied by a corresponding focus on the nuts and bolts of constructing multifactor portfolios. There are essentially two ways to go: In a one-step process, single factor signals are blended into a composite signal and one multifactor portfolio is created from the individual stock composites. Or in a two-step process, single factor portfolios

  • A Bull Bear Background Plotting Function for Octave [Dekalog Blog]

    As part of my recent research I have found it convenient to write another custom plotting function for Octave, which plots a single line price plot against a conditionally coloured background, e.g. two separate colours for bull and bear market regimes. Being able to plot like this avoids the necessity to keep flipping between two separate charts to compare the plot of a potential input feature and
  • Weekly Recap: ETF Tax Efficiency, Profitability Factor, Trend Following [Alpha Architect]

    This week Ryan and I have a discussion on three topics. First, we discuss ETF tax efficiency based on the findings in a new paper by the RAFI team. Second, we discuss the profitability factor as Larry Swedroe highlights a new paper on international evidence. Third, we discuss my article on how one should benchmark a trend following strategy.

  • Scaling/ normalisation/ standardisation: a pervasive question [Quant Dare]

    One of the most asked questions when dealing with several features is how you can summarise or transform them to similar scales. As you probably know, many Machine Learning algorithms demand the input features being in similar scales. But, what if they arent? Can we just work with raw data in the hope that our analysis will be right? Well, in some cases, the answer is yes. When you use
  • The Profitability Factor: International Evidence [Alpha Architect]

    Robert Novy-Marxs 2013 paper The Other Side of Value: The Gross Profitability Premium not only provided investors with new insights into the cross-section of stock returns, but also helped further explain some of Warren Buffetts superior performance. (Wes Gray summarized that paper here.) His study built upon the 2006 paper Profitability, Investment and Average Returns by Eugene

  • Backtesting a Dividend Strategy [Alvarez Quant Trading]

    I was recently at a NWTTA presentation about the S&P 500 Dividend Aristocrats and how to trade these stocks. The strategy was part quantitative and part discretionary. It was popular talk with lots of good questions. People always seem interested in dividend stocks but for me they are just another stock with another reason to go up or down. I dont like to dismiss ideas without

  • Generation AI – The New Data-Driven Investor: Event takeaways, slides & videos [Raven Pack]

    Close to 1,000 finance professionals registered to attend the event, an increase of nearly 50% from last years event. Surely, artificial intelligence and big data continues to grab the attention of the investment industry. The event took place on September 12, 2018 at the Convene Center by Times Square in Midtown, New York. In case you weren't able to attend and listen to the valuable
  • What is the correct benchmark for trend following? [Alpha Architect]

    What is the correct benchmark for trend following? This is a difficult question, and there really is no perfect answer. As many of our readers know, we are fans of trend following and trend-followed portfolios. For those unfamiliar with trend following, the idea is rather simpleinvest in an asset class if the price/return to that asset class is trending up. If not, go to cash or hedge
  • Extended Backtest of Global Equities Momentum [Dual Momentum]

    In 2013, I created my Global Equities Momentum (GEM) model that applied dual momentum to stock and bond indices. We hold U.S. or non-U.S. stock indices when stocks are strong. Bonds are a safe harbor when stocks are weak. When my book was published in 2014, I had Barclays bond index data back to 1973. Since one year of data is needed to initialize the model, GEM results were from 1974 through

  • A Carry-Trend-Hedge Approach to Duration Timing [Flirting with Models]

    In this paper we discuss simple rules for timing exposure to 10-year U.S. Treasuries. We explore signals based upon the slope of the yield curve (carry), prior returns (trend), and prior equity returns (hedge). We implement long/short implementations of each strategy covering the time period of 1962-2018. We find that all three methods improve both total and risk-adjusted returns
  • Improving the Odds of Value [Factor Research]

    Value investors earn a premium for holding undesirable stocks Market skewness may identify periods where the premium is more attractive The returns from the Value factor since 1926 were zero when market skewness was negative INTRODUCTION Although buying cheap stocks is intuitively appealing, holding them is highly unappealing for most investors. Value stocks tend to be companies that lack growth,
  • Price Movement Prediction [Eran Raviv]

    Just finished reading the paper Stock Markets Price Movement Prediction With LSTM Neural Networks. The abstract attractively reads: The results that were obtained are promising, getting up to an average of 55.9% of accuracy when predicting if the price of a particular stock is going to go up or not in the near future., I took the bait. You shouldnt. In short, the authors use over 170

  • A Look At How Fridays Create The Most Reliable Bounces [Quantifiable Edges]

    Friday is generally not terribly reliable in being a day where the market bounces from a low. It is one of the least popular days for this to occur (along with Wednesday). But a potential positive about a Friday bounce is that when they do occur, they tend to be the most reliable moving forward. The below tables look at performance following a bounce from a 50-day low. The 1st table looks at

  • The predictability of market-wide earnings revisions [SR SV]

    Forward earnings yields are a key metric for the valuation of an equity market. Helpfully, I/B/E/S and DataStream publish forward earnings forecasts of analysts on a market-wide index basis. Unfortunately, updates of these data are delayed by multiple lags. This can make them inaccurate and misleading in times of rapidly changing macroeconomic conditions. Indeed, there is strong empirical evidence

  • Conference: AI and Data Science in Trading, NYC March 2019

    There is so much hype and confusion surrounding AI and alt data at the moment. The AI & Data Science in Trading conference separates the hype from the reality Professor David Hand, Imperial College, London Finding alpha has always required asset managers to raise the bar in terms of technology. Today, the combination of endless new data sources, cheap computing and new AI techniques
  • Back to Back 50-day Lows and Extremely Low RSI(2) Readings [Quantifiable Edges]

    Strongly oversold markets often contain a short-term upside edge. Of course oversold can always become more oversold. Wednesday took the SPX down to a 50-day closing low. Additionally, many short-term price oscillators, like the RSI(2) showed extremely low readings. Further selling on Thursday meant another 50-day low and even lower readings. The study below appeared in the Quantifinder on
  • Swimming Against the Current [Alpha Scientist]

    Several weeks back, I posted some work I had done on ETF fund flows and what they could tell us about how investors, on average, fare with respect to timing their entries and exits. TL;DR: Most investors are terrible at timing inflows and outflows to the market. They badly trail benchmarks because they tend to pile in near the top and exit the markets near the bottom. The consistently correct
  • Consistent Momentum with Regime Filters [Sutherland Research]

    In this post were going to continue our work with the Consistent Momentum strategy that we explored here. Initial investigation of the strategy (kindly provided by the good folk at Quantpedia) proved to be relatively good, with a CAGR of +19% and a single losing year through the test period. One shortfall however was the significant drawdown that investors had to endure to achieve the

  • How a Multi-factor Portfolio is Constructed Matters [Alpha Architect]

    The CAPM was the first formal asset-pricing model. Market beta was its sole factor. With the 1992 publication of their paper, The Cross-Section of Expected Stock Returns, Eugene Fama and Kenneth French introduced a new-and-improved three-factor model, adding size and value to market beta as factors that not only provided premiums, but also helped further explain the differences in returns of
  • “Black Swan” Data Cleaning [Dekalog Blog]

    Since my last post I have been investigating training features that can be derived from my Currency Strength indicator as input for machine learning algorithms and during this work it was obvious that there are instances in the raw data that are Black Swan outliers. This can be seen in the chart below as pronounced spikes. The chart itself is a plot of log returns of various forex crosses and Gold
