So do we know now what hedge fund was liquidating yesterday? Someone who owned huge stakes in $Apple (AAPL.US)$ $NVIDIA (NVDA.US)$ and $Microsoft (MSFT.US)$ (but not $Meta Platforms (FB.US)$ or $Amazon (AMZN.US)$ ) dumped a massive amount on open & then again after lunch, and also closed all the Ponzi shorts in the short book, triggering a squeeze.
