Few assets follow ARKK as closely as VTI, which ranks #1 of 122 tracked partners. The trailing year gives VTI the advantage: +15.7% versus +20.7%, a 5.0-point spread. The rolling one-year correlation stayed in a tight band between 0.69 and 0.88 over the past three years, which points to a structural rather than episodic relationship. Note the risk asymmetry: ARKK runs 2.7 times the annualized volatility of the other leg, so equal-weighting the two is not an equal-risk position.
