  • Stock Market Prices Do Not Follow Random Walks [Turing Finance]

    Because volatility seems to cluster in real life as well as the markets, it has been a while since my last article. Sorry about that. Today we will be taking our first giant leap along A Non-Random Walk down Wall Street. The Non-Random Walk Series A Non-Random Walk Down Wall Street is the cheeky title of an academically challenging textbook written by Lo and MacKinlay in response to the
  • God, Buffett, and the Three Oenophiles [Flirting with Models]

    Our friends at Alpha Architect just wrote a great piece titled "Even God Would Get Fired as an Active Investor." In the study, they show that while an omnipotent investor with perfect foresight would have delivered great returns over the long run, he would be fired many times along the way due to short-term underperformance. Quoting from the post: "Our bottom line result is that
  • Does Academic Research Destroy Stock Return Predictability? (h/t @AbnormalReturns)

    We study the out?of?sample and post?publication return predictability of 97 variables shown to predict cross?sectional stock returns. Portfolio returns are 26% lower out?of?sample and 58% lower post?publication. The out?of?sample decline is an upper bound estimate of data mining effects. We estimate a 32% (58%-26%) lower return from publication?informed trading.

  • Architecture -II- [Algorythmn Trader]

    My previous post was about my thoughts concerning general architecture of a trading platform. During my way rethinking it from end to end it becomes clear that a client only approach would not fit with my needs. So I went back to my list of entities and started the puzzling again. To see all past posts and get a outlook about whats coming up, just have a look here: Content++. The obvious
  • Profit Margins – Are they Predicting a Crash? [Jonathan Kinlay]

    Is Jeremy Grantham, co-founder and CIO of GMO bullish or bearish these days? According to Myles Udland at Business Insider, hes both. He quotes Grantham: I think the global economy and the U.S. in particular will do better than the bears believe it will because they appear to underestimate the slow-burning but huge positive of much-reduced resource prices in the U.S. and the availability of
  • Quant Hunt: Ignore Tick-Box Companies [Quant at Risk]

    I was really surprised by a huge popularity of the past section of QuantAtRisk entitled Motivation for Quants. My readers made me thinking. Again. If there is a need for posts that expose and discuss the naked truth about quant job space, lets make it, again! This time bigger, better, and with big big balls! Therefore, this is the very first post in a new series of Quant Hunt. This is where we
  • Data Mining vs Out of Sample Data [Throwing Good Money]

    So in this last post, I data-mined the hell out of the S&P500 index (well ok SPY) and found an anomaly: every time SPY drops more than 1% from the previous close to the current close, you wait (thats Day 0). You then buy at the close 13 days later, and sell at the close of Day 14. This showed significantly better return than if you did the same thing but owned all the Day 16s instead.
  • Interview with Murray Ruggiero [Better System Trader]

    Murray Ruggiero is the chief systems designer and market analyst at Tuttle Tactical Management with around 200 million dollars under management. He is one of the worlds foremost experts on the use of intermarket and trend analysis in locating and confirming developing price moves in the markets. He is also a speaker, author and has been a contributing editor to Futures magazine since 1994,
  • Managing Risk in Retirement: Part II [Blue Sky AM]

    The Challenge of Being a Passive Investor Investors face the prospect of poor expected long-term returns making buying and holding less desirable for both equity and bond holders Given that bond yields are so low, investors are being forced to hold risky assets such as equities to earn sufficient returns. This forces passive investors to have to tolerate substantial volatility. Passive investing
  • C# Historical Dividend retrieval [Smile of Thales]

    Today in SmileOfThales we will provide you some brief but useful C# code (the whole code is available at the end of the article) to retrieve historical cash dividend data in Excel. The topic covers Excel-Dna, data caching, Html parsing with HtmlAgilityPack thats it and its already pretty 🙂 At the very beginning I needed to retrieve dividend history to experiment implicit dividend
  • Stocks That Triple In One Year [Investor’s Field Guide]

    There have been 1,700 individual U.S. stocks (with starting market caps of at least $200MM, inflation adjusted) which have tripled in a 12-month period since 1962. Many of these individual stocks tripled in more than one 12-month period, so we have 7,500 or so separate observations of a stock tripling in a 12-month period. Tripling your money quickly is pretty good. So what do these three-baggers

  • Autocorrelation of SPY, and the Redneck Correlogram [Throwing Good Money]

    Ive been reading books by Michael Halls-Moore and my head hurts. Not having any formal training in statistics, I only understand about half of the material. None the less, I found his discussion of correlograms interesting. I even installed R on my computer (even though I havent fully grasped Python yet!) and was able to make some correlograms with R. However not knowing anything about
  • Loosening Short Sale Constraints Makes Markets More Efficient [Alpha Architect]

    We examine the causal effect of limits to arbitrage on ten well-known asset pricing anomalies using Regulation SHO, which reduced the cost of short selling for a random set of pilot stocks, as a natural experiment. We find that the anomalies become substantially weaker on portfolios constructed with pilot stocks during the pilot period. Regulation SHO reduces the anomaly long-short portfolio
  • When Risk Doesn t Lead To Return [Larry Swedroe]

    Among the more notable anomalies in modern finance is the finding that the lowest-beta stocks have produced higher returns than the highest-beta stocks. Another anomaly is that idiosyncratic (diversifiable) volatility negatively predicts equity returns. In other words, stocks with the lowest idiosyncratic volatility outperform stocks with the highest idiosyncratic volatility. These findings have
  • Replicating Private Equity [Quantpedia]

    Private equity funds tend to select relatively small firms with low EBITDA multiples. Publicly traded equities with these characteristics have high risk-adjusted returns after controlling for common factors typically associated with value stocks. Hold-to-maturity accounting of portfolio net asset value eliminates the majority of measured risk. A passive portfolio of small, low EBITDA multiple

  • Fitting time series models to the forex market: are ARIMA/GARCH predictions profitable? [Robot Wealth]

    Recently, I wrote about fitting mean-reversion time series models to financial data and using the models predictions as the basis of a trading strategy. Continuing my exploration of time series modelling, I decided to research the autoregressive and conditionally heteroskedastic family of time series models. In particular, I wanted to understand the autogressive integrated moving average

  • Does my Tail Look Fat in This? Part 2 [Cantab Capital]

    Investors and managers are concerned with fat tails. In the second part of this post, we look at kurtosis in more detail. An apology and a warning This piece is more technical and longer than I had expected. The problem we're looking at here is subtle and not easy to distill down to a short, punchy and maths-free post. Sometimes the world isn't simple. Introduction In Part 1 of
  • MythBusters: Oil Driving Stocks More Than Ever? [Flirting with Models]

    As the news cycle spins faster and faster, we are seeing more and more market observations based on gut feelings. One such observation that I have heard recently is that oil and energy are driving stocks more than ever before. I thought we would look to the hard data in our own version of MythBusters. So what does the data say? Below we plot three sets of rolling 1-year correlations using data
  • State of Trend Following in January [Au Tra Sy]

  • The Strong Historical Tendency for the Feb Employment Report [InvestiQuant]

    I have discussed the employment report a number of times here on the blog. Over the years the release of the report has generated a high amount of volatility for overnight trades. While the direction of those volatile moves has undergone some big hot and cold streaks, it has not provided a consistent long-term directional edge except around Groundhog Day. Below are results of going long the

  • Fama French Multifactor Model in Python [Largecap Trader]

    Factor modelling is everywhere these days. I wrote about smart beta here. It is good to quantify performance drivers but the usual caveats apply to quantitative studies utilizing backward looking data, past performance does not guarantee future results. I wanted to share a little exercise I did in Python comparing a fund, stock, or anything with a ticker available on Yahoo Finance with the
  • Dream team: Combining classifiers [Quant Dare]

    Can a set of weak systems turn into a single strong system? When you are in front of a complex classification problem, often the case with financial markets, different approaches may appear while searching for a solution. These systems can estimate the classification and sometimes none of them is better than the rest. In this case, a reasonable choice is to keep them all and then create a final
  • Trend Following: Good Start to 2016 [Wisdom Trading]

    Similarly to last year, trend following starts the year on strong footing. January returned over 5% for our trend following index after flirting with the double-digit territory to establish new all-time highs. Below is the full State of Trend Following report as of last month. Performance is hypothetical. Chart for January:
  • SPX Straddle – Normalized Return Charts [DTR Trading]

    The last article on RUT straddles (here) was very popular, so I thought I'd write a similar post on SPX straddles. Recall that from September, 2015 through November, 2015 I reviewed the backtest results form 28,840 short options straddles on the S&P 500 Index (SPX). You can read the summary articles from that SPX series here and here, and the introductory article for the straddle series

  • The three oenophiles [Flirting with Models]

    Summary Most investment strategies can be broken down into the risk premia they wish to harvest, whether it is vanilla like the equity risk premium or more exotic, like the value premium. Different risk premia mature at different rates. Value can take years to mature while momentum can take only a few weeks. Aligning your approach to rebalancing with how long you expect the premium to take to

  • Correlations, Weights, Multipliers…. (pysystemtrade) [Investment Idiocy]

    This post serves three main purposes: Firstly, I'm going to explain the main features I've just added to my python back-testing package pysystemtrade; namely the ability to estimate parameters that were fixed before: forecast and instrument weights; plus forecast and instrument diversification multipliers. (See here for a full list of what's in version 0.2.1) Secondly I'll be
  • Computers vs Humans – considering the median [Investment Idiocy]

    Or why you aren't, and will never be, John Paulson The systematic versus discretionary trading argument is alive and well; or if you prefer, computers versus humans*. In this post I pose the question – who is better the average systematic trader, or the average discretionary human? * Though even fully discretionary traders will be relying on a computer at some point; fully manual trading and
  • The most concise explanation of behavioral finance I’ve ever seen [Alpha Architect]

    One of the most overused and misunderstood terms Ive seen used by finance practitioners is behavioral finance. Many professionals consider themselves to be behavioral finance experts because they identify irrational investors.1 Newsflash: Identifying irrational investors is not behavioral finance. But here is a great summary from a Baker, Bradley, and Wurgler paper weve
  • Peak Crashes: Are They a Shortable Opportunity? [Throwing Good Money]

    In hindsight, its fun to look at stocks that have had a huge surge, only to collapse violently after they peak. And by fun I mean sitting on the sidelines watching, as opposed to pulling ones hair out when youre long that particular trade. Above you can see Apple (AAPL) in 2008, where it hit its 52-week high, only to collapse a few days later, for a very significant loss. Are these
  • Latest Twist In The Stock Market s Wild 2016 Ride [Dana Lyons]

    The stock markets wild ride to begin the year continues, with the latest twist reminiscent of a roller coaster. Over the past 4 days, the Dow Jones Industrial Average (DJIA) has moved at least 1%, with each day alternating up and down. Since 1900, this is the 68th such streak and just the 17th in the past 70 years (actually, today narrowly missed making it 5 days in a row which would have been
