In the previous post on using R for portfolio analysis and design, we discovered that global diversification across asset classes has been modestly beneficial relative to a basic 60%/40% US stock/bond allocation. The global aspect didn’t add a lot of value because US equities during the sample

There is a seasonal influence that could have a bullish impact on the market this week. Op-ex week in general is pretty bullish. March, April, October, and December it has been especially so. S&P 500 options began trading in mid-1983. The table below is one I have showed on the blog in years

I am going to take a short break from reviewing backtest results for different variations of Iron Condors, and revisit Momentum Rotation strategies. In a past post (Historical Data and Momentum Rotation Strategies), I discussed how data choices impact the repeatability of ranking output typically

I have 4 Bitcoin L3 exchange feeds running smoothly out of a data center in California (which is slightly closer to Asian exchanges and Coinbase than the east coast). It took a bit of error handling and exponential back-off, to handle the unreliability of connectivity with these exchanges, where

Another hotly anticipated FOMC meeting kicks off next week, so I thought it would be timely to highlight a less well-known working paper, “Stock Returns over the FOMC Cycle”, by Cieslak, Morse and Vissing-Jorgensen (current draft June 2014). Its main result is: Over the last 20 years, the

More and more frequently I come across people who express an interest in R, and I thought I would share some advice to help people decide if R is something they should use, as well as some high level advice on getting started. Most of these people are developers with at least few years experience

Next week is options expiration week. March is the first time of the year when stock options, index options, index futures, and single-stock/ETF futures all expire at the same time. This event is often referred to as Quadruple Witching or as we prefer to call it in the Stock Trader’s Almanac (page

This study sought to disentangle the effects of size and whether there are size and momentum effects on Jordan firm returns. Initial findings showed that size effect has important role in explaining returns. For momentum effect, while in general there is no momentum effect in Jordan firm market, the

The nation's recent financial crisis brought into sharp relief fundamental questions concerning the social function and purpose of the financial system, including its relation to the "real" economy. This Article argues that, to answer these questions, we must recapture a distinctively

You can use the Piotroski F-Score to improve most investment strategies, not just a low price to book strategy as Joseph Piotroski successfully proved in his 2000 research paper "Value Investing: The Use of Historical Financial Statement Information to Separate Winners from Losers". How to

Do popular capitalization-based exchange-traded funds (ETF) confirm the existence of a reliably exploitable size effect? To investigate, we compare the difference in equally weighted returns (small minus large) for the following matched pair of small-large ETFs: iShares Russell 2000 Index (Smallcap)

Momentum in firm fundamentals, i.e., earnings momentum, explains the performance of strategies based on price momentum. Earnings surprise measures subsume past performance in cross sectional regressions of returns on firm characteristics, and the time-series performance of price momentum strategies

In a prior blog post, I wrote about a simple formula that can be utilized to understand the impact that rising rates may have upon a constant maturity fixed-income index. Emanuel Derman wrote a similar post about constant duration indices. While most people are aware of duration and how to use it to

We examine the causal effect of limits-to-arbitrage on ten well-known asset pricing anomalies using Regulation SHO as a natural experiment. We find that asset pricing anomalies become weaker on portfolios constructed with pilot stocks during the pilot period. The effect is both statistically and

Creating a trading strategy is only the first step to trading successfully. You must then evaluate its performance and decide if you can trust it on a live account. While so much attention gets paid to coming up with a strategy, there is surprisingly little on how to tell if the strategy is any

Yesterday we shared a link to a video showing how Python’s Networkx package could be combined with Gephi to produce some stunning network visualizations. Today we wanted to use these same tools to look at the correlation structure of the S&P 500. To do so, we took the correlation matrix of the
