How correlated are ARKK and COIN?
On 3 years of weekly data the ARKK/COIN correlation comes out at 0.74, strong. Recent behaviour matches the longer record: 0.77 over 1 year against 0.74 over 3. The 5-year figure is 0.75, and annualized covariance runs at 2289.1 %².
Within ARKK's tracked universe of 122 assets, COIN comes in at #15 by 3-year correlation. Their recent paths diverged sharply: over the last 12 months ARKK outperformed by 54.0 percentage points (+15.7% for ARKK against -38.3% for COIN). The rolling one-year correlation stayed in a tight band between 0.64 and 0.85 over the past three years, which points to a structural rather than episodic relationship. Note the risk asymmetry: COIN runs 2.1 times the annualized volatility of the other leg, so equal-weighting the two is not an equal-risk position.
