How correlated are GD and TRT?
On 3 years of weekly data the GD/TRT correlation comes out at -0.26, negative, meaning they tend to move in opposite directions. The link has loosened recently: the 1-year correlation (-0.46) runs below the 3-year figure (-0.26). The 5-year figure is -0.14, and annualized covariance runs at -579.4 %².
TRT is close to the least connected end of GD's tracked universe, ranking #30 of 30. Correlation aside, the last 12 months split them widely, with TRT ahead by 276.7 points (+18.8% versus +295.5%). Note the risk asymmetry: TRT runs 5.1 times the annualized volatility of the other leg, so equal-weighting the two is not an equal-risk position.
