  • How to turn off a strategy using historical volatility [Alvarez Quant Trading]

    A very common question I get, is when should I turn off a strategy? Given the very volatile markets we have had the last few months, I can relate.

  • Option-Based Trend Following [Flirting with Models]

    The convex payoff profile of trend following strategies naturally lends itself to comparative analysis with option strategies. To isolate the two extremes of paying for whipsaw either up front or in arrears we replicate an option strategy that buys 1-month at-the-money calls and puts based on the trend signal. We find that while option premiums steadily eat away at the balance of the

  • Can Statistics Actually Determine if Managers Have No Skill? [Alpha Architect]

    Whether they are selecting a manager, a factor, or a strategy, investors can make two types of mistakes. We thought we were hiring Peter Lynch, not this loser! A Type I error (or false discovery) when selecting a manager who turns out to be unskilled. That Warren Buffett guy is washed up, lets pass. A type II error (missed discovery) when not selecting or missing a manager that the investor

  • Petra on Programming: Truncated Indicators [Financial Hacker]

    Cumulative indicators, such as the EMA or MACD, are affected not only by previous candles, but by a theoretically infinite history of candles. This makes them return slightly different results depending on the tested period. Although this effect is often assumed negligible, John Ehlers demonstrated in his July S&C article that it is not so. At least not for some indicators, such as a narrow
  • Fighting racism starts with a baby step [Ran Aroussi]

    While most people agree that black lives matter (why shouln't they?), many also feel that the "PC Police" has gone too far with demands to ban movies like "Gone with the Wind", removing statues of historical figures, or renaming words like "blacklist".

  • Do Option Prices Inform Stock Returns? [Alpha Architect]

    In perfectly efficient markets, option prices should not convey any new information or contribute to the price discovery of underlying assets. However, if markets are not perfectly efficient, traders with private information might prefer to transact in option markets over stock markets even though option markets are less liquid than the markets in the underlying stocks. The reason for the
  • More Work on RVFL Networks [Dekalog Blog]

    Back in November last year I posted about Random Vector Functional Link (RVFL) networks here and here. Since then, along with my recent work on Oanda's API Octave functions and Market/Volume Profile visualisation, I have continued looking at RVFL networks and this post is an update on this work.

  • Trading Costs Wipe Out the Overnight Return Anomaly [Alpha Architect]

    At least once a year, the press and Twittersphere propagate the mistaken idea that investors can earn excess returns by buying the S&P 500 at the close of the market, then selling it at the open the next day. The logic is that by exposing themselves to only overnight returns, investors can seek to harness some form of information surprises by the way of earnings announcements or idiosyncratic
