"to new investors"Yeah, to the MARKET via an MM. Don't fall for the doublespeak. If the block was sold to a new investor, they'd have to file a 13-D form.
Shkreli dumped the shares via an MM into the market and squared up the multi-week sells out of the block(s) at the VWAP of the MM's trades.
Very unlikely that a large individual buyer took Shkreli's large blocks.
