There is, large market moves down over last few days are mostly due to hedge funds selling off longs to cover their shorts. If you look at GSVIP ETF (GS ETF for most loved names by hedge funds) it was down 4% yesterday. The short squeeze is real but I think funds are mostly out of it now (or ones remaining in the short have shorted at higher prices and in reasonable proportion of AUM). There's also a direct negative correlation between short interest and Russel 2000 performance over the last few days.
