Today’s article is an update on this oldie but goodie. When people ask me if momentum investing “works”, at this point – because I am older and (even) crankier than I used to be – I typically refer them to the linked article above and grunt “decide for yourself.” Sorry, it’s just my

This past year we examined the possibility of replicating commodity exposure via equities. The project was spurred by an insightful research report from MSCI, which showed some impressive results. Other research outfits have proposed similar concepts. The figure below, taken from the MSCI report,

In this post we look at the backtest results of selling a one-lot, at-the-money (ATM) straddle on the S&P 500 Index (SPX), initiated at 38 days-to-expiration (DTE). In this second post of five on 38 DTE straddles, we look at trades that use the same loss exits as shown in the first post, and in

This week on the podcast I have algorithmic trader, Kevin Davey. Who like many guests in the past, he comes from a background in engineering – there’s something about these engineers, they seem to make really great traders… After getting off to a bumpy start 25 years ago, Kevin has come a very

Dr Ernie Chan does something difficult well: he explains quantitative trading ideas to retail traders without over-simplifying them. He has written two books," Quantitative Trading:How to Build Your Own Algorithmic Trading Business" and "Algorithmic Trading: Winning Strategies and

The NFL is back!!! Unfortunately, the Eagles may need a new kicker…and now we have to listen to Wes talk trash about the Cowboys victory around the office. Tragic! In the spirit of the new NFL season, I figured it was a good time to highlight a newer paper titled “Corporate Sport Sponsorship and

This post will deal with applying the constant-volatility procedure written about by Barroso and Santa Clara in their paper "Momentum Has Its Moments". The last two posts dealt with evaluating the intelligence of the signal-generation process. While the strategy showed itself to be

SPX closed at a 10-day high on Tuesday. New short-term (and intermediate-term) highs will sometimes get traders excited. When the market is in long-term downtrend mode, this excitement is often misplaced. Way back in a blog post on 4/3/09 I showed a number of “systems” that looked to sell short

Hackers would make great traders. At a meta level, hackers and traders do the same thing: they find and exploit the weaknesses of a system. The difference is that hackers hack computers, networks, and even people for various good and bad reasons whereas traders hack financial markets to make

In the previous set of articles (Parts 1, 2 and 3) we went into significant detail about the AR(p), MA(q) and ARMA(p,q) linear time series models. We used these models to generate simulated data sets, fitted models to recover parameters and then applied these models to financial equities data. In

This is the first article in a series where we will look at the performance of selling at-the-money (ATM) options straddles. For background on the setup for the backtests, as well as the nomenclature used in the charts and tables below, please see the introductory article for this series: Option

For the last 6 months I have been focused on the process of building the full technology stack of an automated trading system. I have come across many challenges and learnt a great deal about the two different methods of backtesting (Vectorised and Event driven). In my journey to building an event

In pair trading, usually a pair of stocks is traded in a market neutral strategy, i.e. it doesn’t matter whether market is trending upwards or downwards, the two open positions for each stock hedge against each other. To be able to pair trade, the key challenges are to: Choose a pair which will

In my previous post I demonstrated how a risk parity portfolio could be calculated numerically using a Newton method. However, the more common problem is to be able to set risk budget constraints as opposed to having equal risk. We can do this with PCTR constrained optimization by setting PCTR

"Taking less risk than is optimal is not safer; it just locks in a worse outcome. Taking more risk than is optimal also results in a worse outcome, and often leads to complete disaster." -- Aaron Brown, Red Blooded Risk (2011) In our new white paper, we explore how tactical strategies can

Factor analysis has taken the professional consultant world by storm and we are slowly seeing this analysis being used more and more by sophisticated retail investors and investment advisors. And that’s great–factor analysis is a great tool. In fact, we discuss the use of the tool and how it is

I've been thinking more about technical analysis. Not so much how to do it, but more about what it actually is. Some of it can be tested scientifically, but a lot can't (for more on this distinction refer to the excellent book by David Aronson, "Evidence-Based Technical Analysis:

This post will show how to use Monte Carlo to test for signal intelligence. Although I had rejected this strategy in the last post, I was asked to do a monte-carlo analysis of a thousand random portfolios to see how the various signal processes performed against said distribution. Essentially, the

In this blog post, I will present some backtest results on volatility models. The list I present here are not exhaustive and there are still a gargantuan set of papers focusing on this issue (a good place to start is on vlab [s.o to @neighbourlybear for showing me this]). In the next section, I

Nobody can deny a simple empirical fact: higher fees are associated with lower returns, on average (Here is a great paper by Ken French on the costs of active investing). This finding, logically, leads investors to focus on low-cost solutions as opposed to high-cost solutions, all else equal. But do

Yesterday I discussed Tuesday’s Follow Through Day (FTD) and some possible implication based on breadth and volume statistics. Wednesday was interesting because we saw a big selloff immediately follow Tuesday’s FTD. Past occurrences of this have been somewhat rare, but also somewhat suggestive

Officially end my exams on 28 Aug 15. Since I started a year back, I have learnt so much about finance, although I still think it’s not enough. In my opinion, I think there are 2 main school of thoughts in finance. One track is about trying to come out with models and price a certain financial

Its somewhat shocking to think about, but the mathematical underpinnings of modern finance have existed since at least 1898 when an obscure french mathematician Louis Bachelier was first getting started on what would become known as random walks. The two centuries prior to Bachelier witnessed the

VIX mean reversion trade gets popular when the market experiences big ups and downs. You hear a lot of talks about how much money people make from trading VXX, XIV and their leveraged equivalents. However, is VIX truly mean reverting, or it seems more lucrative than it is just because people only

Using a large dataset of news releases, we study instances of investors’ mistaken reaction, or misreaction, to news. We define misreaction as stock prices moving in the direction opposite to the news when it is released. We find that news tone predicts returns in the cross-section only upon the

One notable bit of evidence that emerged on Tuesday was the fact that it qualified as an IBD Follow Through Day (FTD). I have done a lot of research on FTDs over the years. Much of that research can be found on the blog. Here is a link. http://quantifiableedges.com/category/ibd-follow-through-day/ A

This post will evaluate signals based on the rank regression hypotheses covered in the last post. The last time around, we saw that rank regression had a very statistically significant result. Therefore, the next step would be to evaluate the basic signals — whether or not there is statistical

How much influence do investors have over their portfolios? Perhaps it's less than commonly assumed. The notion that randomness plays a role in money management has been widely studied in finance-Nassim Taleb's popular treatment in Fooled by Randomness: The Hidden Role of Chance in Life

Large institutions deal with immense amounts of currencies which enter and leave their accounts on a daily bases. Furthermore they have their own funds that it has to efficiently allocate so as to maximize their return on investment but also wish to hedge against adverse events. With a certain
