  • When Simplicity Met Fragility [Flirting with Models]

    Research suggests that simple heuristics are often far more robust than more complicated, theoretically optimal solutions. Taken too far, we believe simplicity can actually introduce significant fragility into an investment process. Using trend equity as an example, we demonstrate how using only a single signal to drive portfolio allocations can make a portfolio highly sensitive to the impact of

  • Missing the best or worst market days [Alvarez Quant Trading]

    This morning I saw the chart on Ritholz.com of what happens when you miss the best X days of the market. I see a variation of this chart often and is used to argue why someone should not try and time the market. One concept I like to do is to invert. Meaning try the opposite idea and see what you get. What I rarely see is the chart if you missed the worst X days. Given it is a rainy Sunday morning

  • Variance term premia [SR SV]

    Variance term premia are surcharges on traded volatility that compensate for bearing volatility risk in respect to underlying asset prices over different forward horizons.

  • Explaining The Robot ETF s Bull Run With Factor Analysis [Capital Spectator]

    Bloomberg last week published an intriguing story about a new exchange traded fund (ETF) that uses artificial intelligence (AI) to outperform market indexes and active managers alike. The implication: a new era of AI-driven investing has dawned, putting the standard applications of indexing at a disadvantage. Yet a closer look at the so-called Robot ETFs results via a factor-analysis lens tells

  • How large is the tracking error created by trend following? [Alpha Architect]

My response is the following: Tracking error. First, what is tracking error?(1) Tracking error is a measure of how much a strategy deviates from a benchmark. If you are a U.S. equity investor, a standard benchmark is the SP500.(2) One
  • Elevated CBI And New SPX Low Carry Bullish Implications [Quantifiable Edges]

    As we approached the close I noted on Twitter (@QuantEdges) that the Quantifiable Edges Capitulative Breadth Index (CBI) was starting to spike. And the closer we got to 4pm EST, the higher it got. At the end of the day, the CBI finished at 10, which is a level I have long considered bullish. The combination of a 10+ CBI and a 50-day closing low is something I have shown in the past to be bullish
  • Creating our own S&P 500 Momentum ETF [Quant Dare]

    Smart Beta ETFs are achieving an increasing popularity, seen as the perfect equilibrium between passive investment and active management.

  • 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

  • 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.

  • 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
