ARK Innovation ETF matches S&P 500 returns in 10 years but with double volatility and weak risk-adjusted returns.

Over the past decade, the ARK Innovation ETF (ARKK) has delivered returns comparable to the S&P 500 but with more than twice the volatility, resulting in a lower risk-adjusted performance as shown by its 10-year Sharpe Ratio of 0.33 versus the S&P 500's 0.74. Current portfolio valuations of ARKK are very high, not justified even by the strong growth prospects of its holdings. Given this risk-return profile and valuation, there is little reason to prefer ARKK over broader market ETFs or selecting individual stocks.
