A Site Devoted to Finding a Trading Edge

I'd like to call attention to the excellent site, which conducts research on historical market patterns.

Here is a page with links to their various research articles. Among the topics you'll find are moving average crossover patterns, VIX patterns, and sentiment patterns with put/call ratios. The article on predicting the VIX itself is particularly interesting.'s most recent post develops an idea that I recently advanced: looking at the relationship between gold and technology as a sentiment measure. Technology, as a growth sector, benefits from risk-seeking sentiment in the market; gold, as a safe haven, benefits from risk aversion. That suggests that the relative performance of gold to technology might provide a nice window into the risk appetites of traders and investors.

What they found was that, when the 3-day exponential moving average of the gold:technology ratio was below the 3-day simple moving average, returns for gold were above average. Indeed, cumulative returns from such a strategy look compelling (although further refinement to reduce drawdowns would be needed).

The reason such a strategy works, they suggest, is that profits from risk-seeking assets tend to flow toward risk-averse ones. An alternative interpretation is that dips in the gold:technology ratio represent trader/investor overreactions that tend to correct over time. If that is the case, then we should expect short-term outperformance by any safe haven to have bullish implications prospectively.

My next post will examine just such a possibility.


Finding Gain Where There's Been Pain

I think referring to gold prices in the past 5yr as measure of sentiment and/or inflation expectations is complicated by the argument that core *demand* has changed. So, while there may be some very short-term inefficiencies to exploit, one needs to be aware of the historical changes in gold's price behavior.

Here's a reference to an academic research about the abnormal correlation between gold and stocks in the past 5yr.

Hi T,

Great point; the supply/demand equation for gold could alter these relationships. Thanks for the link--
