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.
