“The Technical Analysis Challenge” (pdf) 07 October 2003

Abstract: We report on a study of the ability of analysts to distinguish an actual price series of an equity from random alternatives. Virtually all of the statistical tests on the results support the hypothesis that no skill was exhibited in selecting the correct response. Many of the analysts were extremely over-confident about their ability to select correct answers. The one area where it seems skill might have been exhibited is in the selection of correct answers that happened to be far from the random choices.

“Portfolio Sharpening” (pdf) 21 September 2003

Abstract: We explore the effective gain or loss in alpha from the point of view of the investor due to the volatility of a fund and its correlations to other asset classes. Fund managers and investors can be guided by this to increase the utility that is ultimately delivered to the investor. In this analysis of investor utility, the Sharpe ratio is shown to be misleading and the tracking error has no role at all. A new class of funds — called “hyperpassive” — is suggested which are similar to traditional index funds, but which aim to deliver a comparable expected return with less volatility than the benchmark. It is also shown that the optimal allocation to additional asset classes can be surprisingly high when the correlations are small. Accompanying software is available in the public domain area.

    I am pretty skeptical of technical analysis for individual stocks, but I do think the general market can be predicted with some accuracy based on economic information. Fortune had a good article on timing the market here.
