  • Long-Short Investing Might Shorten Your Investment Lifespan [Alpha Architect]

    Over the past several decades, academics have identified numerous variables that seem to predict future expected returns. This has led to a proliferation of so-called factors identified in the literature, and created what John Cochrane has labeled the factor zoo. Now we we have a zoo of new factors. The Journal of Finance 2010 Presidential Address Enter the zoo at your own risk
  • Momentum: Letting the Cheap Get Cheaper? [Flirting with Models]

    As an investment strategy, momentum focuses solely on prior returns. Being valuation agnostic, however, does not mean that a momentum strategy does not have first-order valuation effects on portfolio construction. Using historical US sector data, we find that both cross-sectional and time-series momentum strategies may serve as good diversifiers to the potential risks of large structural repricing
  • Does Risk Parity Maximize Risk-adjusted Returns? [Markov Processes]

    While it is well known that risk parity strategies typically allocate more weight or apply leverage to asset classes with lower risk, it is not well understood how higher volatility affects the Sharpe ratios exhibited by the assets that get over- or under- weighted.

  • Central Moments [Eran Raviv]

    Sometimes I read academic literature, and often times those papers contain some proofs.

  • Testing A Euro Currency Futures Scalping Strategy, Part 6 [System Trader Success]

    In an attempt to make this system more tradable, Ive looked at many different stop methods and filters.

  • Five points of caution for dividend investors [Factor Investor]

    At a time when demand for income generating assets is at an all-time high, the yields on income generating assets are at, or near, all-time lows. While the headlines often speak to the number of Baby Boomers entering retirement, the more important statistic is actually the amount of wealth entering retirement.

  • Preliminary Tests of Currency Strength Indicator [Dekalog Blog]

    Since my last post on the currency strength indicator I have been conducting a series of basic randomisation tests to see if the indicator has better than random predictive ability. The first test was a random permutation test, as described in Aronson's Evidence Based Technical Analysis book, the code for which I have previously posted on my Data Snooping Tests Github page. These results were

  • Outperforming by Underperforming [Flirting with Models]

    If you want long-term outperformance, you must be able to stomach short-term underperformance. As William Bernstein said, The most important investment ability is an emotional discipline.

  • Python Data Visualization using Bokeh for Algo Traders and Quants [Quant Insti]

    A picture is worth a thousand words or said a wise woman a hundred years ago. True to every word of the idiom, the beauty of visualization lies in how clearly it might convey multiple messages.
