  • Market-Making Portfolio & Hedging [Tr8dr]

    With market making we can try to be neutral by skewing prices in such a way as to maintain a neutral position. To the extent that the market can become 1-sided (in momentum) or may have large sized requests (if offering at different sizes), ones portfolio may require explicit hedging. In a live market-making scenario we can determine how we want to hedge on a case-by-cas

  • VIX Trading Strategies in April [Volatility Made Simple]

    Weve tested 23 simple strategies for trading VIX ETPs on this blog (separate and unrelated to our own strategy). And while I cant speak for all traders, based on all of my readings both academic and in the blogosphere, the strategies weve tested are broadly representative of how the vast majority of traders are timing these products. Most of these strategies turned in solid performances
  • Could Stocks AND Bonds Be Topping? [Dana Lyons]

    There is always a small but vocal contingent of market pundits calling for a stock market top. In the past few years, there has been a very large but now sheepishly quiet contingent of analysts calling for a top in bonds (i.e., rise in rates). One thing you dont hear too often, however, is a call for a major top in stocks and bonds. Now that would be a double whammy for investors! If you want
  • A Simple Test of the Predictability of Large Daily Changes in SPY [Psych Signal]

    We know market sentiment metrics used as a stand-alone signal – can predict market changes over minutes and sometimes longer. But what about the vital issue of really big day-to-day changes? And what if we add the simplest of daily price dynamics to the daily sentiment metric-based predictive model? Here we present tests of how well daily sentiments predict big market shifts. We take daily

  • Better portfolio building: How system returns correlate under edgeless environments [Mechanical Forex]

    The topic of system return correlations is extremely important as it forms the main pillar of successful portfolio building. Portfolio theory encourages us to put together different systems which are uncorrelated historically, such that our level of expected risk adjusted returns will increase as a result of an increase in compounding efficiency and an increased hedging of drawdown periods between
  • ETFReplay.com Portfolio May Update [Scott’s Investments]

    The ETFReplay.com Portfolio holdings have been updated for April 2015. I previously detailed here and here how an investor can use ETFReplay.com to screen for best performing ETFs based on momentum and volatility. The portfolio begins with a static basket of 14 ETFs. These 14 ETFs are ranked by 6 month total returns (weighted 40%), 3 month total returns (weighted 30%), and 3 month price volatility
  • RUT Iron Condor – Dynamic Exit – 66 DTE – 20 Delta Continued [DTR Trading]

    This post is a continuation of the prior post. In this post we will look at the backtest results for dynamic exits of the 66 days-to-expiration (DTE) Iron Condor (IC), with 20 delta short strikes, with different profit and loss exits as a percentage of the initial credit. Recall that these RUT ICs were all constructed with 20 point wide credit spreads. This is a non-directional options trading str

  • How Smart are “Smart Beta” ETFs? [Alpha Architect]

    Many consider smart beta to be a revolution in the asset management industry. For example, Bloomberg ran an article, Funds Run by Robots Now Accounts for $400 Billion, which caught our attention. According to this article, Smart beta, is one of the fastest growing segments of ETFs, accounting for nearly 20% of all assets in domestic ETFs as of the end of 2014. The secret sauce of
  • Can you avoid rising rates with high carry assets? [Flirting with Models]

    First: the takeaways Expected return for an asset class is a combination of carry and price appreciation If carry is high enough, it can potentially dwarf price depreciation due to rising rates Higher carry assets (e.g. high yield bonds, MLPs, REITs, bank loans, EM debt, et cetera) have historically had low-to-negative estimated duration profiles High carry assets have a variety of associated risk
  • Is That Back-Test Result Good or Just Lucky? [Adaptrade]

    When developing trading strategies, most systematic traders understand that if you search long enough, you're bound to find something that looks great in back-testing. The question is whether those great results are from a great trading strategy or because the best looking strategy was the one that benefited the most from good luck. A well-known metaphor for this is a roomful of monkeys
  • System building – Data capture [Investment Idiocy]

    A while ago I ran a series of posts on how you would write some python code to systematically trade using the interactive brokers C++ API. Whilst I hope this was helpful it was just a starting point. There are at least two major projects to undertake before one could actually trade. The first is the design of such a system. This is the subject of a book I am writing, which I hope will be published
  • RUT Iron Condor – Dynamic Exit – 66 DTE – 16 Delta [DTR Trading]

    In this post we will look at the backtest results for dynamic exits of the 66 days-to-expiration (DTE) Iron Condor (IC) options strategy, with 16 delta short strikes, with different profit and loss exits.

    Reader Eli asked in the comments "I used to program in Matlab a lot in the past. Now I feel that Python is a better way to go. Any thoughts? Yes, quite a few – however I also hope to hear some ideas from other readers. Matlab is an excellent tool for analytics, and I have been using it for over a decade now. However if I were starting out in quantitative finance today I would probably go with

    Ive never seen a bad backtest Dimitris Melas, head of research at MSCI. About backtests A backtest is a simulation of a trading strategy used to evaluate how effective the strategy might have been if it were traded historically. Backtestesting is used by hedge funds and other researchers to test strategies before real capital is applied. Backtests are valuable because they enable
  • International Value Investing: Looks Like a Reasonable Bet [Alpha Architect]

    A rich body of literature has shown that value investing, or buying stocks that are cheap based on a variety of valuation metrics, is robust across different markets. For example, Fama and French (1998) highlighted the value premium across world equity markets. The authors find that value portfolios yield higher average returns than growth portfolios in 12 out of the 13 countries analyzed

  • How to Avoid Losing 95% in Ford [Jay On The Markets]

    No, were not talking resale value here (in which case losing 95% of your original investment is a distinct possibility). We are talking about stock ownership. In a nutshell, the answer is fairly simple: *It is OK to drive a Ford in late summer into fall. But it is NOT OK (apparently) to own Ford stock during late summer into fall.

  • How to Trade the MACD: A High-level Analysis of the MACD Line Feature [System Trader Success]

  • When SOX Falls As NDX Has A Strong Day [Quantifiable Edges]

    One interesting aspect of Fridays action was the discrepancy between the NDX and the SOX. While the NDX rose 1.3%, the SOX declined 1.7% which is very unusual action. Below is an updated study that looks at times the NDX rose by a least 1% while the SOX declined. Six days later 76% of the instances were losers and the average occurrence was nearly a 3% loss. That seems to be a fairly
  • Parsimony [CSS Analytics]

    Note: James Picerno of The Capital Spectator recently did an interesting piece evaluating the Self-Similarity Metric and provides some R code which is valuable for many of our readers. The principle of parsimony relates to being frugal with resources such as money or the use of computing time. It is closely tied to the principles of simplicity, elegance and efficiency. It also complements the phil
  • Lessons from the Flash Crash regulatory fiasco [Mathematical Investor]

    On April 21, 2015, the U.S. Department of Justice announced that it would press criminal charges against Mr. Navinder Singh Sarao, a 36-year-old small-time British day-trader. He is being blamed for nothing less than causing the Flash Crash of May 6, 2010, the second largest point swing (1010.14 points) and the biggest one-day point decline (998.5 points) in the history of the Dow Jones

  • Do Iron Butterflies Need to be Adjusted? [DTR Trading]

  • Bond/Utility Divergence a Warning Sign…for the S&P 500? [Dana Lyons]

    Given their relatively high yields, utility stocks have long been thought of as proxies, or at least competition, for bonds. And while that relationship is often overplayed (utility stocks are first and foremost, stocks), there is some credence to the notion. Since 1970, there is a 26% positive correlation in 2-month returns between 10-Year Treasuries and the Dow Jones Utility Average (

    There is a lot of talk about stocks being expensive, but also a lot of people not really doing anything about it. Many simply dont know how to tackle the problem, and others dont want to think about it at all.

  • 1292 Days and Counting Since Last 10% Correction [Almanac Trader]

    Alright, so the S&P 500 declined 1.1% today. That is the worst daily decline since March 25, 2015 when it fell 1.46%. Within this context, todays loss seems far less worrisome than you probably heard today. But, with the current bull market well above average duration and performance since 1949 some jitteriness is to be expected. Plus it has been nearly four years since S&P 500 started

  • Implied Skew Strategy [John Orford]

    Previously, I checked whether historical skewness was a good indicator to buy and sell the S&P 500. My backtesting framework can now use the implied skew index as an indicator to buy or sell. Now, the strategy buys the S&P 500 if the implied skew index has dropped day over day and vice versa. Note that the S&P 500's implied skew is permanently nega
