  • Dynamic Hedge Ratio Between ETF Pairs Using the Kalman Filter [Quant Start]

    A common quant trading technique involves taking two assets that form a cointegrating relationship and utilising a mean-reverting approach to construct a trading strategy.

  • Uncertain Alpha [Flirting with Models]

    SUMMARY We have previously discussed many problems associated with the measurement of alpha. Measurement uncertainty, the choice of model risk factors, and the analysis timeframe can all have significant impacts on the calculation and applicability of alpha, and investors are often hard-pressed to obtain sufficient information surrounding the calculation methods. These problems can be exacerbated

  • Tactical Asset Allocation Software [Meb Faber]

    I used to update an old post on free data sources and stock screeners for investors.

A quick summary of the results from those prior studies: Bonds have historically provided some diversification benefit during bad months for stocks. Bonds have

  • The folly of panic selling [Mathematical Investor]

    Mark Hulbert has compiled an interesting list of recent market panics: August 2015: Concerns about the Chinese economy and stock market led to panic selling, with the Shanghai index plunging 8.5% in one day. Soon after in the U.S., on August 24, 2015, the DJIA plunged over 1,000 points in just a few minutes, its most precipitous drop ever, ending the day down 588 points, its worst one-day loss in

  • Equity Anomalies Persist in International Markets [Quantpedia]

    Motivated by McLean and Pontiff (2016), we study the pre- and post-publication return predictability of 138 anomalies in 39 stock markets. Based on more than a million anomaly country-months, we find that the United States is the only country with a statistically significant and economically meaningful post-publication decline in long/short returns. The surprisingly large differences between the

  • Are Stocks Actually Undervalued? [Flirting with Models]

    Summary We have noticed the market reaching a broad consensus that equities are overvalued, implying a drag on forward expected returns as valuation multiples contract. While there is often great wisdom in the crowd, there can also be great madness. We believe it is prudent to consider how the crowd might be wrong. In this commentary, we explore why valuations matter in the first place and how if
  • Metal Logic [Jonathan Kinlay]

    Precious metals have been in free-fall for several years, as a consequence of the Feds actions to stimulate the economy that have also had the effect of goosing the equity and fixed income markets. All that changed towards the end of 2015, as the Fed moved to a tightening posture. So far, 2016 has been a banner year for metal, with spot prices for platinum, gold and silver up 26%, 28% and 44%
  • Optimizing Mean Variance Optimization [Alpha Architect]

    In the 1950s, Harry Markowitz proposed a method to identify the optimal trade-off between risk and return for a portfolio. The theory is broadly termed, Mean-Variance Optimization (MVO). Sam Wittig, a Drexel graduate I advised and who did some research for Alpha Architect, shared with us his undergraduate thesis project regarding Markowitzs analysis. Here is a link to Sams work:

  • Use Caution With Low Vol Strategies [Larry Swedroe]

    As we have discussed before, one of the major problems for the first formal asset pricing model developed by financial economists, the capital asset pricing model (CAPM), was that it predicts a positive relation between risk and return. But empirical studies have found the actual relation to be flat, or even negative. Over the past five decades, the most defensive stocks have furnished

  • Finding Alpha pdf [Falkenblog]

    My book The Missing Risk Premium is a steal at only $15, but my first book, Finding Alpha, is a $65, which is a bit much for anyone not expensing their books. Finding Alpha goes over why the current asset pricing model fails, with lots of evidence, explains why economists still like it, and then in chapters 10-13 shows concrete examples of how investors have actually found alpha. The risk begets
