1528 ET - Q/C Technologies shares mostly rebounded from a 67% drop Monday and a 52-week low Tuesday, more than doubling late Wednesday. The optical-computing company late Friday disclosed that consulting agreements with an entity affiliated with Martin Shkreli and with OpenAI scientist Chelsea Voss were mutually terminated. Voss also resigned from the board. Earlier Wednesday, adviser James Altucher posted on X about the company's AI-powered platform for chip design, which coincided with an intraday peak in the company's share price. Shares were recently at $1.06, up 139%, amid very volatile trading and still below Friday's close of $1.71.
