Control Thy Risk
Here's my table of highly correlated markets for my Highly Correlated Markets Risk Control Rule, a.k.a. the Don't-Bet-Against-Myself Rule (see more on it on my "How It Works" page and this blog post):
S&P 500: Dow Jones industrials
Dow Jones industrials: BKX Banks Index, S&P 500
NASDAQ 100: n/a
BKX Bank Index: Dow Jones industrials
Nikkei: n/a
Natural gas: n/a
Gold, copper, silver, platinum, heating oil, crude oil (all highly correlated with each other)
Notes:
1) I defined markets as "highly correlated" when their weekly open prices have greater than 0.85 correlation between March 1995 (the start of the combined futures and options Commitments of Traders data) and the end of 2007 (the end of my test data).
2) Markets like the Nikkei and NASDAQ 100 that have the notation "n/a" aren't highly correlated with any other market. These uncorrelated markets are useful for building diversity into my portfolio.
3) No trade will be taken in the case of an equal number of long and short setups in highly correlated markets.
