  • Big Little Details [Flirting with Models]

    Limited attention drives us to focus on the big details of investment strategies. Small details can have an outsized impact on performance, especially if they can compound upon one another. To quote Aaron Brown, Head of Risk at AQR: It takes a lot of compounding to turn a mistake into a disaster. There will never be any shortage of mistakes []. So its the compounding you have to prevent,
  • Know what you don t know with data [Cuemacro]

    Lets say you had to identify a city youd never heard of on a map. Lets take a city chosen at random, Stockton and you wanted to identify which country it is in. You have with you a list of every single town in the world, alongside its country. A simple brute force way to find the country, is literally to go through every town on the list till you get to Stockton. You can obviously use

  • Evaluating Trading Strategies with Random Portfolios [Geodesic Edge]

    Active asset management has been under attack during the past several months. Hedge funds have been shutting down left and right, labeled as overpriced and underperforming, and are losing capital to low cost passive mutual funds and ETFs. Active mutual funds have been losing ground as well to their passive counterparts. Warren Buffet has even gone so far as to refer to hedge fund managers who have

  • March for the Fallen: Get Fit with Alpha Architect [Alpha Architect]

    As a former US Marine, Memorial Day is every day, however, Memorial Day is special because the time is set aside to reflect on those who paid the ultimate sacrifice.

One such event is March for the
  • Testing the Hierarchical Risk Parity algorithm [QuantStrat TradeR]

    This post will be a modified backtest of the Adaptive Asset Allocation backtest from AllocateSmartly, using the Hierarchical Risk Parity algorithm from last post, because Adam Butler was eager to see my results. On a whole, as Adam Butler had told me he had seen, HRP does not generate outperformance when applied to a small, carefully-constructed, diversified-by-selection universe of asset classes,
  • Research Review | 26 May 2017 | Smart Beta [Capital Spectator]

    How much higher can smart beta adoption climb? Now in its fourth year, FTSE Russells latest annual survey of global institutional asset owners indicates that smart beta adoption is at an all time high and that investors continue to find new applications for its use. The survey, Smart beta: 2017 global survey findings from asset owners, reveals that the percentage of asset owners reporting an
  • An Analysis of Momentum Behaviour in the Long-Term [Quantpedia]

    Motivated by behavioral theories, we test whether recent past performance of the momentum strategy (Past Momentum Performance–PMP) negatively predicts the performance of stale momentum portfolios. Following periods of top-quintile PMP, momentum portfolios exhibit strong reversals 2-5 years after formation, whereas, following periods of bottom-quintile PMP, stale momentum portfolios earn positive

  • How Many Assets Are Needed To Test a K-Factor Model? [Alex Chinco]

    Imagine youre a financial economist who thinks that some risk factor,{\color{white}i}f_t, explains the cross-section of expected returns. And, you decide to test your hunch. First, you regress the realized returns of N different assets on{\color{white}i}f_t to estimate each assets exposure to the risk factor, \tilde{b}_n: \begin{equation*} r_{n,t} = \tilde{a}_n + \tilde{b}_n \cdot f_t +
  • The Value Premium: Risk or Mispricing? [Alpha Architect]

    One of the great debates in finance is whether the source of the value premium is risk-based or a behavioral anomaly. In our book, Your Complete Guide to Factor-Based Investing, my co-author Andrew Berkin and I present the evidence showing that there are good arguments on both sides. Thus, its likely the answer isnt black or white. For example, we show that the academic research

  • The Case for Tactical Alpha, Part 3: The Greatest Trick Wall Street Ever Pulled [Invest Resolve]

  • The time has come: setting up a DB with MySQL and R [Quant Bear]

    The recent decision by Yahoo to screw with their API for financial data (and in the process disabling all packages/functions in various programing languages obtaining EOD (end-of-day) data, at least temporarily) shows us two important things: Nothing is free and reliable forever Its a good idea to have a database set up So for everyone in the why do i need a DB/I dont know how to set it
  • The Marcos Lopez de Prado Hierarchical Risk Parity Algorithm [QuantStrat TradeR]

    This post will be about replicating the Marcos Lopez de Prado algorithm from his paper building diversified portfolios that outperform out of sample. This algorithm is one that attempts to make a tradeoff between the classic mean-variance optimization algorithm that takes into account a covariance structure, but is unstable, and an inverse volatility algorithm that ignores covariance, but is more
  • Can We Improve Sector Rotation? [Flirting with Models]

    Momentum-based sector rotation is a popular investment strategy. Recent academic studies have shown that alternative implementations of standard momentum including risk-adjusted momentum, residual momentum, and frog-in-the-pan momentum can significantly improve the risk-adjusted and total return potential of stock-based momentum systems. We explore whether these approaches create

  • How to Scrape and Parse 600 ETF Options in 10 mins with Python and Asyncio [Black Arbs]

    This is Part 1 of a new series I'm doing in semi real-time to build a functional options data dashboard using Python. There are many underlying motivations to attempt this, and several challenges to implementing a tool like this from scratch. Where to get the data? Is it affordable? Easily accessible? API? How to parse the results? How to aggregate and organize the data for analysis? How to
  • Solved: Errors Downloading Stock Price Data from Yahoo Finance [Robot Wealth]

    Recently, Yahoo Finance a popular source of free end-of-day price data made some changes to their server which wreaked a little havoc on anyone relying on it for their algos or simulations. Specifically, Yahoo Finance switched from HTTP to HTTPS and changed the data download URLs. No doubt this is a huge source of frustration, as many backtesting and trading scripts that relied on such
  • Yahoo is dead, long live Yahoo! [Trading with Python]

    On 18 May 2017 the ichart data api of yahoo finance went down, without any notice. And it does not seem like it is coming back. This has left many (including me) with broken code and without a descent free end-of-day data source. Something needs to be done. Now. Apparently Yahoo! does not want us to download free data automatically, but it is still possible to download it by hand, clicking the
  • An Example of Trading Model Design by Richard Olsen (Founder of @OANDA) [Quantpedia]

    We introduce a new approach to algorithmic investment management that yields profitable automated trading strategies. This trading model design is the result of a path of investigation that was chosen nearly three decades ago. Back then, a paradigm change was proposed for the way time is defined in financial markets, based on intrinsic events. This definition lead to the uncovering of a large set

  • Bye Yahoo, and thanks for all the fish [Financial Hacker]

    Just a quick post in the light of a very recent event. Users of financial functions of R, MatLab, Python, or Zorro got a bad surprise in the last days. Many scripts and programs based on historical price data suddenly dont work anymore. And our favorite free historical price data provider, Yahoo, now responds on any access to their API in this way: No, they wont be right back. Their

  • Constant Expiry VIX Futures (Using Public Data) [QuantStrat TradeR]

    This post will be about creating constant expiry (E.G. a rolling 30-day contract) using VIX settlement data from the CBOE and the spot VIX calculation (from Yahoo finance, or wherever else). Although these may be able to be traded under certain circumstances, this is not always the case (where the desired expiry is shorter than the front months time to expiry). The last time I visited this
  • A Direct Test of the Dividend Catering Hypothesis [Alpha Architect]

    Why do CEOs decide to pay dividends? That is an interesting question, and one that academics have been researching for years. Miller and Modigiliani in 1961 show that if one assumes perfect and efficient capital markets, and investors should have no preference as to whether or not a firm pays dividends.(1)(2) However, (some) people care about dividends! But are dividend paying stocks better
  • Testing Dual Momentum with @AllocateSmartly [Scott’s Investments]
