The volume and the share price movement in the last 2 weeks is mainly driven by the short sellers, imho. They are on both sides of the market and are still short selling STX to keep - as good as possible - control over the share price, but decrease their cumulative short position day by day...

One can see this pattern if you are follow the live trading for some time: each buying trade is immediately followed (seconds later) by a selling trade with smaller volume and a replenishment of the last offer position.

A very laborious way for short sellers to slowly reduce a short position and also with the not inconsiderable risk that a sudden change in the fundamental situation (for example, an exception to the existing onshore gas export ban) could trigger a short squeeze. ...the short position in STX had already exceeded 60m shorted shares before the TPD SoA.
