Quote from trump-baja:
Let's take a spread like XOM/CVX , where the 3 year correlation and the 1 year correlation are both high (3 yr: .96 / 1yr: .86 - based on spdrindex.com correlations ) and they are obviously in the same business with comparable macro issues.
When PairTrade Finder does a backtest - how profitable is this pair?
Now, let's compare it to GE/PFE, where the 3 year correlation is decent (.75) and the 1 year correlation is (.89). They are not, however, in the same business.

Just interested in seeing if the buy/sell signal methodology is clever enough to exploit a relatively high correlation for short term trades regardless of longer-term macro exposures.
