  • How to Combine Commodity Style Strategies [Quantpedia]

The framework is flexible enough to be applicable to any asset class for either long-short, long- or short-only styles. We study the nave equal-weighted integration and sophisticated integrations where the style
  • Night Terrors [Highly Evolved Vol]

    Following on from my recent posts about trading volatility over weekends, Im now going to briefly look at trading options overnight. Option traders have always complained when they were too long options overnight, expecting to usually lose money on overnight longs. This doesnt make sense in a pure Black-Scholes-Merton world. In that world the time decay (theta) will be balanced by the
  • Free Friday #20 Time Windows [Build Alpha]

    There has been a recent popularity regarding time windows and it is one I completely agree with! There are certain structural changes that happen throughout the 24 hour session and as a trader it is important to take note of these when designing a system or strategy (or just placing trades). For example, how is my strategy's performance when Asia closes? How about when the US opens? There are

  • StockTwits Sentiment Analysis [EP Chan]

    Exploring alternative datasets to augment financial trading models is currently the hot trend among the quantitative community. With so much social media data out there, its place in financial models has become a popular research discussion. Surely the stock markets performance influences the reactions from the public but if the converse is true, that social media sentiment can be used to
  • Best Operating System For Quant Trading? [Quant Start]

    One question that I am asked frequently is which operating system to use for quantitative trading research and implementation. The short answer, as of the writing date of this article, is if you want to carry out any serious/mathematical quant trading research (machine learning/deep learning) you should make use of Ubuntu 16.04 LTS Linux, with a desktop version on a local research machine and the

  • Time of Day effects in FX [Quant Journey]

    Time of day is critical for trading, it is even possible building trading strategies solely depending on time of day (I will keep this for another post) I will be using the concept of quality and define a high quality market, from an intraday timing perspective, as a market when trading range and volume are high and spread is low. I assume this as a good time to trade as trading cost (spread) is
  • A Random Forest Test For Jumps in Stock Markets Using R [Top of The Bell Curve]

    In the previous article we looked at how one can use Neural Networks to detect jumps present in returns of a particular stock. In this blog post, we build on the thinking established in the previous article and use a Random Forest to detect jumps present in stock market returns. I have build an interactive web application which allows the user to select the share they want to test for jumps, and
  • R vs MATLAB – round 4 [Eran Raviv]

    This is another comparison between R and MATLAB (Python also in the mix this time). In previous rounds we discussed the differences in 3d visualization, differences in syntax and input-output differences. Today is about computational speed. Spoiler alert: MATLAB wins by a knockout. A genuinely fair speed comparison across different software can be tricky. Almost all operations can be coded in more
  • Foreseeing the future: a user s guide [Quant Dare]

    Everybody would like to see the future. If youre a portfolio manager, youd definitely love to see the future. Many posts here on QuantDare deal with the challenge of predicting the future (with Prophet, Random Forests, Lasso, etc). This time, we talk about something different: imagine we are able to predict the future exactly. Now what? How could we exploit this priceless information? As we
  • Modeling Expected Drawdown Risk [Capital Spectator]

    There are no silver bullets for profiling risk, but drawdowns properties arguably give this metric a leg up over most of the competition. The combination of an intuitive framework, simplicity, and sharp focus on how markets actually behave is a tough act to beat. Perhaps the strongest argument in favor of drawdown can be summed up by recognizing that peak-to-trough declines always resonate with
  • Broken Strategy or Market Change: Investigating Underperformance [Alvarez Quant Trading]

    I recently had someone email me about the performance of a strategy I created back in late 2005/early 2006 and traded for a few years. I remember the strategy being a daily mean reversion set up with an intraday pullback entry. I figured it probably had not done well over the last decade. I stopped trading in the middle of 2008 because I did not like how it was behaving. In the backtest it did

  • Leverage Up When You re Down? [QuantStrat TradeR]

    This post will investigate the idea of reducing leverage when drawdowns are small, and increasing leverage as losses accumulate. Its based on the idea that whatever goes up must come down, and whatever comes down generally goes back up. I originally came across this idea from this blog post. So, first off, lets write an easy function that allows replication of this idea. Essentially, we have
  • Getting Started with Neural Networks for Algorithmic Trading [Robot Wealth]

  • The Butterfly Effect in Retirement Planning [Flirting with Models]

    Summary The low current market outlook for stocks and bonds paints a gloomy picture for retirees under common retirement forecasting assumptions.

  • Profit Margins, Bayes Theorem, and the Dangers of Overconfidence [Philosophical Economics]

    Its the fall of 2011. Investors are caught up in fears of another 2008-style financial crisis, this time arising out of schisms in the Eurozone. The S&P 500 is trading at 1200, the same price it traded at in 1998, roughly 13 years earlier, despite the fact that its earnings today are almost three times as high as they were back then. The indexs trailing price-to-earnings (P/E) ratio sits
  • A Look At Historical Post-Labor Day SPX Performance [Quantifiable Edges]

    Way back in 2009 I showed a study that suggested Labor Day week performance has been somewhat dependent on whether the market has rallied over the 20 trading days leading up to it. I decided to take a new look at that study today. Below are updated results of post-Labor Day action when the previous 20 days have seen gains versus losses. 2017-09-04-1 This shows a poor performance record when there

    What are the research questions? Is there a consistent and reliable long term overreaction pattern in global equity markets?

  • Statistical Arbitrage Using Pair Trading In The Mexican Stock Market [Quant Insti]

    There are very few algo trading firms/strategies that are operating in the Mexican stock exchange. I believe this should provide great opportunities as there is little competition. Contrary to a more developed market, arbitrage opportunities arent readily realized which suggests there might be opportunities for those looking and able to take advantage of them. This is the main motivation for

  • Statistical Arbitrage on a Cross-border Soybean Crush Spread [Golden Compass]

    Pairs trading is one of the simplest forms of statistical arbitrage which involves exploiting relative mispricings between two similar assets. It operates based on the assumption of the law of one price; that anomalies among securities valuation will occur in the short run but in the long run, will be corrected by market efficiency. In academic literature, studies such as such as Bogomolov (2010)
  • An Interactive Dynamic Delta Hedging Example in R [Top of The Bell Curve]
