On October 2, 2026, Seagate $STX and Western Digital $WDC each fell 10.2%, while Quantum $QMCO rose 8.2% to its $34.50 peak. $QMCO’s drop started the week before it fired its CFO on October 9, along with a selloff in hard drive stocks. Toshiba, which makes hard drives like $STX and $WDC, said on October 2 that its Philippine plant is “aiming to nearly double its annual production capacity” of data center hard drives by its fiscal year starting April 2027. More hard drive supply could (1) hurt $QMCO by easing the disk shortage that helped push customers toward tape, as I covered in my April 22 tape primer, and (2) help $QMCO by easing the constraints on “certain disk drives” that CEO Hugues Meyrath mentioned on the June-quarter call. From October 2 to October 9, $QMCO fell 11.8%, vs. 4.3-8.0% for SanDisk $SNDK, $STX, and $WDC. Then, from the October 9 close, before the firing was disclosed, to October 27, $QMCO fell another 33.4%, vs. 4.1-17.5% for the three storage stocks. So the storage selloff explains part of the drop from $34.50, but most of it came after the firing, which is specific to $QMCO.
