How correlated are KEYS and VOO?
On 3 years of weekly data the KEYS/VOO correlation comes out at 0.62, strong. The link has loosened recently: the 1-year correlation (0.46) runs below the 3-year figure (0.62). The 5-year figure is 0.64, and annualized covariance runs at 329.9 %².
Within KEYS's tracked universe of 43 assets, VOO comes in at #14 by 3-year correlation. Correlation aside, the last 12 months split them widely, with KEYS ahead by 76.8 points (+97.4% versus +20.6%). Across three years, the rolling one-year figure varied moderately, from 0.43 to 0.80. Note the risk asymmetry: KEYS runs 2.6 times the annualized volatility of the other leg, so equal-weighting the two is not an equal-risk position.

A structural note: 0.09% of VOO is KEYS itself, so the fund partly moves with the stock by construction.
Are KEYS and VOO good diversifiers for each other?
To a limited degree. At 0.62 the two still catch most of the same waves, so the pair smooths returns a little without insulating either from a shared selloff.
