New Paper: The IBS Effect: Mean Reversion in Equity ETFs

I finally finished the first draft of my IBS paper. The results are quite interesting and extremely relevant if you trade equity ETFs. You can read it here.

Abstract:

I investigate mean reversion in equity ETF prices at the daily frequency by employing a simple technical indicator, Internal Bar Strength (IBS). IBS is based on the position of the day’s close in relation to the day’s range. I use it to forecast close-to-close returns with statistically and economically significant results for most instruments. A simple strategy based on IBS generates an average alpha of over 30% p.a. before transaction costs. I show that equity index ETFs have had strong and consistent mean reverting tendencies since the 90s, and that these effects can be exploited as part of a profitable trading strategy. The IBS effect is stronger during times of high volatility, in bear markets, after high-range days, after high-volume days, and early in the week.

Feedback is highly appreciated, either in the comments below or by email to qusmablog at gmail dot com.

 Update: the comparison chart for the Australian ETF now correctly uses EWA instead of EWO (the Austrian ETF).
