  • When Breaking up is Easy To Do [Factor Investor]

    This post is a bit of an experiment. My good friend Steven Wood and I started discussing some collaborations a few months ago.

  • Stitching data for a more ‘balanced’ backtest [Better System Trader]

    When traders set in-sample and out-of-sample periods for their backtests, its common just to pick some dates that split the data into a pre-defined percentage or range. The trouble with this approach is that it often doesnt take into account the type of market environments that exist in those periods. For example, your in-sample period may be very bearish, and if your out-of-sample period is

  • What is Bitcoin’s Fair Value? [Quantpedia]

    We develop a strong diagnostic for bubbles and crashes in bitcoin, by analyzing the coincidence (and its absence) of fundamental and technical indicators.

In these bubbles, we detect a universal

  • Timing Country Exposure with Value: A Valuation Measure Horserace [Alpha Architect]

    Buy cheap. This is a motto many live by, not only in their daily lives but also in their investment philosophy. Historically, buying cheap stocks was a good idea (i.e., the so-called value premium). But how might valuation matter when it comes to country allocations? In other words, given valuations, how much money should I allocate to U.S. equity and how much should I allocate to

  • Diversifying the What, How, and When of Trend Following [Flirting with Models]

    Nave and simple long/flat trend following approaches have demonstrated considerable consistency and success in U.S. equities.

  • Trading rules that keep you trading [Alvarez Quant Trading]

    I have written the difficulty in trading and testing short strategies. I had stopped trading my short strategy because it was too hard to trade psychologically for me. About nine months ago, I revisited my short strategy to see how it had been doing since I stopped and of course it has been doing just fine even during these very bullish times. As strategy developers we often add rules to improve
  • Holy Bullish Thursday!! [Quantifiable Edges]

    Stock market performance leading up to and around many holidays has often been bullish. This is something I have written about several times over the years.

  • How Algo Trading Reacts to Market Stress [Quantpedia]

    A key issue raised by the rapid growth of computerised algorithmic trading is how it responds in extreme situations.

  • Risk-Based Explanations for the Momentum Premium [Alpha Architect]

    Most of the literature on the momentum factor has focused on behavioral explanations, generally either investor underreaction or overreaction.

That causes momentum. For example, there is ample evidence

  • Two Centuries of Momentum [Flirting with Models]

    A momentum-based investing approach can be confusing to investors who are often told that chasing performance is a massive mistake and timing the market is impossible. Yet as a systematized strategy, momentum sits upon nearly a quarter century of positive academic evidence and a century of successful empirical results. Our firm, Newfound Research, was founded in August 2008 to offer

    There are a hundred ways to evaluate whether an investment is cheap–discounted cash flows, competitor multiples, mean reversion, multiple of projected earnings–the list goes on…and on.
