  • The Cold Blood Index [Financial Hacker]

    Youve developed a new trading system. All tests produced impressive results. So you started it live. And are down by $2000 after 2 months. What now? Carry on in cold blood, or pull the brakes in panic? This is a situation all too familiar to any algo trader. There can be several reasons why a strategy loses money right from the start. It can be already expired since the market inefficiency
  • You do not experience summary statistics [Flirting with Models]

    In due diligence, we often evaluate summary statistics like annualized return, volatility, alpha, beta, up-capture, and down-capture. These statistics can unify years of returns into a single number. While this can be convenient for comparing different strategies, it fails to provide adequate insight into the actual week-to-week experiences an investor will face. We highlight how even in the best
  • Buy the Winners [Systematic Relative Strength]

    People come up with all kinds of reasons not to buy stocks with strong momentum. Some of the most common reasons that I hear: Stocks with high momentum are risky Stocks with high momentum are overvalued Stocks with high momentum are susceptible to reversals As for the first point, yes, buying stocks with high momentum is risky. So is buying stocks with weak momentum. As far as that goes, buying
  • A Complementary Approach To Trading Technical Indicators [System Trader Success]

    In the October issue of Futures magazine author Jean Folger discusses an important aspect when selecting two or more indicators when developing a trading system. While I dont recommend simply combining indicators to create a trading system, and I dont think thats what Folger is suggesting either, when there comes a time to introduce two or more technical indicators to a trading system,

  • Best Links of the Week [Quantocracy]

    My fellow quant nerds, we need to vote more. Less than 2% of clickthroughs result in a vote. Thats just not enough. A vote doesnt mean a link is the greatest of all time, only that its good and deserves to be read by others. Higher rated links are read significantly more often, so help me to encourage bloggers to write quality content by making your voice heard. I do my part by providing
  • Highlights from Episodes 1-20 [Better System Trader]

    This weeks show is going to be a little different to previous episodes. A couple of weeks ago I went back through all the guests weve had on the show so far and realised how very fortunate weve been to have so many fantastic guests on the show, sharing their knowledge and experience, some of them with more than 50 years of trading experience! To be honest, Id actually forgotten some of

  • Stock Volatility Moves Treasurys [Larry Swedroe]

    Understanding the volatility of Treasury bond returns, as well as the volatility of both the level and slope of the Treasury term-structure, are fundamental issues in finance. Whats more, they have important implications for investors and portfolio design. Researchers have offered both theory and empirical evidence that suggest important linkages between equity risk and the Treasury bond
  • Utilizing the Value of Value to Make Value / Growth Tilts [EconomPic]

    Back in August I outlined why I thought the plain-vanilla value premium had been compressed to the point growth had and was likely to continue to outperform in my post Death of (Plain Vanilla) Value – Long Live GARP.

  • Information Ratio Hypothesis Testing [John Orford]

    Spurned by reading an account of a trader who swears by machine learning, few days ago I wrote about aesthetics in finance. Maths and tech without a narrative is pointless. My own attempts at providing a narrative foundered a few months back. Suspend Your Disbelief! I started using the Sharpe as a hypothesis test. So for example, the S&P 500 (not including dividends) has a Sharpe of ~0.462
  • Insider Trading During the 8-K Trading Gap [Alpha Architect]

    SEC rules allow companies to delay the public disclosure of significant corporate events for up to 4 business days. This information is reported on an 8-K. This 4-day gap between an event and the disclosure creates an interesting situation. As an insider, if I know an 8-K is going to report news, I may want to try and trade in that 4 day window when the information is not available to the broader
  • Biotech: My love-hate relationship [Alvarez Quant Trading]

    The two charts above are from recent trades I have taken. Charts created in AmiBroker. On July 20, 2015 IBB, iShares Nasdaq Biotechnology ETF, made a closing high of 398. About three months later it closed at 289 for 27% loss. A very common thing I hear from traders is that they dont trade biotechnology or pharmaceutical stocks. I completely understand. These stocks tend to be very

  • Did the CME Data change impact your strategies? [System Trader Success]

    Effective September 21, 2015 the CME changed the closing time for futures that closed at 5:15 PM ET from 5:15 to 5:00 PM. The CME did this because the volume from 5:00 PM to 5:15 PM just wasnt that significant. My initial thought was no big deal, my strategies hardly ever traded during that time anyhow. Turns out, I was wrong. It could be a HUGE deal, depending on your strategies.

  • Sovereign High Yield Bond Strategy [Meb Faber]

    There is ample research that shows that sorting government bonds on yield works great. The outperformance has been very consistent over the years at about 2% a year.

These are returns from going long high yielding and short low yielding countries, but one issue with that strategy is that the drawdowns

  • Surprise…Trading More is Profitable for Active Funds! [Alpha Architect]

    Warren Buffett make it clear why frequent trading damages ones wealth: Wall Street makes its money on activity. You make your money on inactivity. (source) But is activity always a bad thing?

  • Guns, Bombs and eSports: Applying Data and Portfolio Analytics to Counter-Strike Gambling [Kevin Pei]

    Since the publication of Bill James' seminal work, Baseball Abstract, and the rise to stardom for the Oakland A's, Sports Analytics – the application of statistics to competitive sports – has been (and still is) a prominent topic within the industry.

  • Seasonality debunked (partially) [RRSP Strategy]

  • Apples and Oranges: A Random Portfolio Case Study [GestaltU]

    This article was motivated by a provocative discussion with a thoughtful RIA. Lets call him Harry.

Harrys definition of GTAA is any strategy that regularly alters its allocation across a wide
  • How to make proper equity simulations on a budget Part 1 Data [Following the Trend]

    Simulating an equity strategy is difficult. Much more so than simulating a futures strategy. Theres a lot more moving parts to care about. Much more complexity.

When I set out to write Stocks on the Move, I wanted to make sure that

  • When process and performance disagree [Flirting with Models]

    Summary Due diligence often focuses on the three Ps: people, philosophy, and process. There is an important 4th P: performance. When a portfolio has a consistent process, performance can ebb and flow as the strategy goes in or out of favor. For example, value stocks have been out of favor for 8 years. If a strategy goes through an extended period of underperformance, we must ask whether the

  • Multivariate volatility forecasting (3), Exponentially weighted model [Eran Raviv]

In a corporation settings your manager and his manager and so forth MUST feel
  • Giving up on Runge-Kutta Methods (for now?) [Dekalog Blog]

    Over the last few weeks I have been looking at using Runge-Kutta methods for the creation of features, but I have decided to give up on this for now simply because I think I have found a better way to accomplish what I want. I was alerted to this possible approach by this post over at http://dsp.stackexchange.com/ and following up on this I remembered that a few years ago I coded up John
  • Value Investing: The Pain Train has Arrived and it Sucks [Alpha Architect]
