Development-stage and/or midcap bios such as IDIX, REGN, PDLI, VPHM, HNAB, ONXX, etc. probably keep slipping because of the two hedge funds liquidating (one of them is rumored to be a healthcare only fund).
There are also rumors circulating of some larger, leveraged funds caught on the wrong side of the Fed trade, also some may have been caught when the margin requirements for copper futures were raised. If any of these rumored, leveraged funds were also long biotech, then there could be forced liquidations as well in the sector.
