Evidence behind the moves

Liquidia Corporation (LQDA) -57.19%

A federal court found two asserted patent claims valid and infringed by Liquidia's YUTREPIA. Liquidia said the remedy remained uncertain and it intended to pursue appellate options. An unusually large, highly traded decline tied to a ruling affecting a marketed drug.

Jabil Inc. (JBL) -10.03%

Jabil reported fiscal fourth-quarter results and issued its fiscal 2027 outlook.

Gen Digital Inc. (GEN) +5.61%

Shares rebounded amid continuing attention to a reported GoDaddy takeover approach. Gen Digital's chief executive had separately addressed the company's acquisition strategy in a September 28 post filed with the SEC; a completed transaction was not announced. A sizable rebound in a liquid cybersecurity name with an unresolved acquisition story.

General Mills, Inc. (GIS) -4.91%

General Mills announced that Chief Operating Officer Dana McNabb would succeed Jeff Harmening as CEO, effective January 1, 2027.
