How correlated are DUK and GOOG?
Over the past 3 years, DUK and GOOG moved with a correlation of -0.31, which is negative, meaning they tend to move in opposite directions.

GOOG is close to the least connected end of DUK's tracked universe, ranking #52 of 53. The last year tells two different stories: GOOG led by 61.6 percentage points, +1.1% for DUK against +62.7% for GOOG. Do not treat this figure as fixed: across three years the rolling one-year correlation ranged all the way from -0.42 to 0.09. Note the risk asymmetry: GOOG runs 2.0 times the annualized volatility of the other leg, so equal-weighting the two is not an equal-risk position.
