  • Download Intraday Stock Data with IEX and Parquet [Black Arbs]

    IEX is a relatively new exchange (founded in 2012). For our purposes, what makes them different from other exchanges is they provide a robust FREE API to query their stock exchange data.

Apache Parquet is a columnar storage format available to any project in the Hadoop ecosystem, regardless
  • Are Investors Becoming Better at Fund Picking? [Quantpedia]

  • False Promises: Going Passive is Not Momentum Investing [Factor Investor]

    There is some popular marketing spin going around that indexingconstructing portfolios based on market-cap weightsis effective because it allows an investor to own more of companies that have been successful and appreciated, while moving away from losers that have been unsuccessful and declined. This sounds logical, but it is empirically wrong. The strategy suggested above is tantamount to a

  • RSI2 (Relative Strength Index) Analysis [Alvarez Quant Trading]

    From my time with working with Larry Connors, I have become known for using the 2-Period RSI (RSI2) (Relative Strength Index) in my trading. I have written lots of blog posts that use it and I often use it in my personal strategies. One thing I like to do with indicators that I use frequently is a thorough analysis of them. Often, I find characteristics that I did not expect. Do you know about the
  • Hedge Fund Return Predictability [Rayner Gobran]

    This is the sixth in my Hedge Fund Hacks series. In this post, I hammer home how little we know about the expected returns of a hedge fund or a managed futures strategy because we have so little data. You will learn just how large the uncertainty is and what you can do about it. Glimpses Through the Fog I remember hiking with my wife in North Wales in the Spring of 2003. Wales tends to be cloudy
  • New video explains the danger of selection bias in finance [Mathematical Investor]

    A new video has been produced by the Mathematicians Against Fraudulent Financial and Investment Advice (MAFFIA) group.

  • Estimating the Hurst Exponent Using R/S Range [Flare 9x]

    In this post we will estimate the Hurst exponent using the R/S method. The Hurst exponent determines the long range memory of a time series (more below). If a series has no memory ie if each point in time is independent from previous points in time then its said to be more of a random process. Examples of random processes are markov processes, Brownian motion and white noise. A series which trends

  • Commodities for the Long Run [Alpha Architect]

    The paper investigates this issue by answering the following research questions: Are commodities returns positive on average?

What are the Academic Insights? By studying a novel dataset consisting of daily futures prices going
  • Better Returns From Seasonal Investing In The S&P 500 (1950-2018) [iMarketSignals]

    From 1950 to 2018 the S&P 500 performed best from November to April, and significantly worse from May to October during most years.

  • The Siren of Statistics [Highly Evolved Vol]

    A siren was a mythological being who lured sailors with their enchanting music to shipwreck on the rocky coasts of their island. Their songs were almost impossible to resist. But more generally a siren is a bad thing that we are attracted to, either physically or psychologically. For investors, an example of a sirens song is simplicity. Many investors are prone to looking for just a few
  • Factor Fimbulwinter [Flirting with Models]

    Value investing continues to experience a trough of sorrow. In particular, the traditional price-to-book factor has failed to establish new highs since December 2006 and sits in a 25% drawdown. While price-to-book has been the academic measure of choice for 25+ years, many practitioners have begun to question its value (pun intended). We have also witnessed the turning of the tides against the

  • The Future for Factor Investing May Be Different Than its Backtested Past [Alpha Architect]

    We believe there are cause and effect relationships in the world and in investing that hold true over time. Many are common sense and easily observable like fire creates smoke while others are harder to see and understand. With factor investing, true relationships can be hard to see because of randomness and noise in data, and theres a risk we convince ourselves certain
  • FX carry strategies (part 1) [SR SV]

    FX forward-implied carry is a valid basis for investment strategies because it is related to policy subsidies and risk premia. However, it also contains misdirection such as rational expectations of currency depreciation. To increase the signal-noise ratio FX carry should at the very least be adjusted for expected inflation differentials and external deficits. Even with such plausible

  • Kelly versus Classical portfolio theory, and the two kinds of uncertainty premium [Investment Idiocy]

    Since I was a young lad there has been an ongoing fight in Financial Academia 'n' Industry between two opposing camps: In the red corner are the Utilitarians. The people of classical finance, of efficient frontiers, of optimising for maximum return at some level of maximum risk. In the blue corner are the Kellyites. Worshipping at the feet of John Kelly and Ed Thorpe they have only one
  • Update on Improved Currency Strength Indicator [Dekalog Blog]

    Following on from my previous post I have now slightly changed the logic and coding behind the idea, which can be seen in the code snippet below Essentially the change simultaneously optimises, using Octave's fminunc function, for both the gold_x and all currency_x geometric multipliers together rather than just optimising for gold and then analytically deriving the currency multipliers.

  • Currency Management with FX Style Factors [Quantpedia]

    Currency hedging is often approached with an all-or-nothing mentality: either full hedging of all foreign exchange (FX) positions or no hedging at all. As a more nuanced alternative, we suggest systematically harvesting the benefits of the FX style factors carry, value and momentum. In particular, we demonstrate how these factors can expand the opportunity set of traditional asset allocation when

  • Factors from Scratch with Philosophical Economics (@Jesse_Livermore)

In terms of growth and excitement, Uber has the clear edge. But in this paper we're going to
