How correlated are EXC and LRCX?
Over the past 3 years, EXC and LRCX moved with a correlation of -0.21, which is negative, meaning they tend to move in opposite directions. The link has tightened recently: the 1-year correlation (-0.09) runs above the 3-year figure (-0.21). Over 5 years the correlation is -0.02, and the annualized covariance of weekly returns is -193.7 %².
By 3-year correlation, LRCX places #27 of the 41 assets tracked against EXC. Their recent paths diverged sharply: over the last 12 months LRCX outperformed by 207.3 percentage points (+1.7% for EXC against +209.0% for LRCX). The relationship is regime-dependent: the rolling one-year correlation swung between -0.52 and 0.22 over the past three years, so this pair behaves very differently depending on the market environment. Note the risk asymmetry: LRCX runs 2.4 times the annualized volatility of the other leg, so equal-weighting the two is not an equal-risk position.
