The ARK Innovation ETF (NYSE:ARKK) has had a brutal year, falling more than 60% over the past 12 months compared to just a negative 2.5% total return for the SPDR S&P 500 ETF Trust (NYSE:SPY) in that same stretch.
The ARKK fund has bounced a bit in three weeks, gaining 5% overall. However, former hedge fund manager Whitney Tilson said Monday that investors should think twice before buying the dip in the ARKK fund.
