  • The Unbearable Transience of Alpha [Quandl]

    In 2004 I enjoyed my 15 minutes of fame for an article I wrote called The Tao of Alpha, in which I explained the concept of alpha as a zero-sum game. Sources of alpha in 2004 were much different than those available in the mid-1990s when I started my career and they are also different from todays. Alpha is highly transient and has been coming and going for as long as capital markets have
  • Pair Trading Strategy and Backtesting using Quantstrat [Quant Insti]

    One of my favorite classes during EPAT was the one on statistical arbitrage, so the pair trading strategy seemed a nice idea for me. My strategy triggers new orders when the pair ratio of the prices of the stocks diverge from the mean. But in order to work, we first have to test for the pair to be cointegrated. If the pair ratio is cointegrated, the ratio is mean-reverting and the greater the
  • Evidence-Based Investing Requires Less Religion and More Reason [Alpha Architect]

    During the 1600s, the Dutch had a large merchant fleet and the port city of Amsterdam was a dominant commercial hub for trade from around the world. Based on the growing influence of the Dutch Republic, in 1602 the Dutch East India Company was founded, and its evolution into the first publicly traded global corporation drove a number of financial innovations to the Amsterdam Stock Exchange,

  • Paper: The Trinity Portfolio [Meb Faber]

    Lets say one sets out to design a portfolio, knowing everything we know today about investing. Where would a logical, evidence-based investor even start? Investors today have access to more market data and strategic information than at any other time in history. While beneficial in some ways, this huge volume of fragmented information presents a challenge how should one actually implement

  • What is the Proper Benchmark for Momentum or Trend-Following Strategies? [Blue Sky AM]

    Most academics and practitioners tend to compare momentum or trend-following strategies to a buy and hold investment strategy. They do so by comparing the results of the strategies to a benchmark that is a proxy for buy and hold. From this type of analysis many experts justify why the strategies are either superior to buy and hold, or on the contrary side why they arent worth pursuing.

  • Portfolio selection, Laplace equation and Random Walk [Tulip Quant]

    Suppose you would like to invest 1000$ in two stocks, and you have to decide how much money you should put into these two stocks. You could use some Modern Portfolio Theory for that, for example. However, I would like to talk about a second approach, which is quite curious in my opinion. This post is based on this text by Julio Rossi, from the University of Buenos Aires. In this text, the
  • From trading ideas to robust strategies [Better System Trader]

    To prepare for the previous episode on system trading through the Brexit, I had to dig through some of the past podcast episodes for background information. As I was going through them I realized there was so much great information there, some that I had already forgotten about. Such a shame, all that valuable trading information just sitting there, waiting for our attention, so I thought it must

  • What Drives Momentum Performance? [EconomPic]

    Mar Vista Investment Partners has a really interesting research piece out The Price You Pay which has a great table outlining the benefit of an asymmetric return profile (i.e. having more market exposure during up markets than down markets). It is a mathematical truism that superior down capture in negative periods provides more capital for compounding in the ensuing positive periods. Using
  • The Arbitrage of Price-to-Book [Portfolio Perfection]

    The trending value strategy buys the top 25 stocks by their 6 month price momentum among the top decile of stocks ranked by value composite 2 (VC2), a combination of price-to-earnings ratio, price-to-sales ratio, price-to-book ratio, earnings before interest tax depreciation and amortization to enterprise value ratio (EBITDA/EV), price-to-cash flow ratio, and shareholder yield.

  • Quantitative Strategy Development Overview Brian Peterson [Open Source Quant]

    I have had the pleasure of getting to know and work with Brian Peterson of late building out the blotter::mcsim function in the blotter package. I will be writing about this function soon and where it is headed, but in this post i wanted to share a presentation Brian gave the CapeR User Group last week on Developing and Backtesting Systematic Trading Strategies with an application in R, and in
  • Risk Managing Risk Management [Flirting with Models]

    Well, despite some recent market turmoil from the Brexit, the S&P 500 is still hovering near its high from last year on a price basis. If we include the reinvestment of dividends, then we have already seen new highs in April, May, and June of this year. As we wrote about previously, a bear market might be the only way to boost the expected returns on U.S. equities. Investor who thought they
  • Stale Performance Chasing: Beware of Horizon Effects [Alpha Architect]

    Investors talk a big game when describing how they evaluate mutual funds. They say they consider things like the objectives of the fund, its size, and the longevity of its managers. But theres one factor that looms larger than all the others: Performance. We wrote here about how investors tend to chase the performance of funds, allocating to funds that have done well, and redeeming from

Here you can download the presentation Many thanks to all who attended and particularly for the engaging questions. I thoroughly enjoyed myself!

  • Unbalanced Classes in Machine Learning and the Stock Market [MKTSTK]

    Many assets exhibit bull or bear trends which persist for long periods of time. This presents an interesting problem for anyone trying to predict the future return of an asset: a lack of diversity in your training set. This problem is known as unbalanced classes in the machine learning field. The basic issue is that many classification methods work best when your training data is roughly uniform
  • Hull Moving Average Filter | Trading Strategy (Entry & Exit) [Oxford Capital]

  • Impact of 1987 Black Monday on Trading Behavior of Stock Investors [Quantpedia]

    Using a simple sign test, we report new empirical evidence, taken from both the US and the German stock markets, showing that trading behavior substantially changed around Black Monday in 1987. It turned out that before Black Monday investors behaved more as in the momentum strategy; and after Black Monday more as in the contrarian strategy. We argue that crashes, in general, themselves are merely

  • Introduction to Zipline in Python [Quant Insti]

    Python has emerged as one of the most popular language for programmers in financial trading, due to its ease of availability, user-friendliness and presence of sufficient scientific libraries like Pandas, NumPy, PyAlgoTrade, Pybacktest and more. Python serves as an excellent choice for automated trading when the trading frequency is low/medium, i.e. for trades which do not last less than a few
  • Style Momentum in Australia? [Alpha Architect]

    Jegadeesh and Titman (1993) popularized a simple idea: "past winners outperform past losers." Post JT, the relative strength, or "momentum anomaly," was forever ingrained in the minds of academic researchers (which is odd, since the idea had been around 50 years prior to JT 1993, but I digress). Later studiiessee Meb Faber, Gary Antonacci, or the new Haghani and Dewey

The firms listed include the likes of Renaissance Technologies, D.E. Shaw, Two Sigma, Millennium, Citadel and Schonfeld, none of
  • Combining Different Momentum Factors [Systematic Relative Strength]

    Momentum can be calculated in a number of different ways. As long as you are measuring the strength of price appreciation over an intermediate time horizon most logical calculation methods will work to one degree or another. The standard, academic definition of momentum usually means taking the price appreciation of a security over a predefined time period and comparing it to all of the other
