Micron, Southwest Airlines, and Accenture Increase in Premarket Trading; CarMax and Sonos Decline

US stock futures were higher on Thursday, recovering after a previous session that broke a winning streak.

Here are some notable premarket US stock movers today:

• Micron stock surged by 16% after the chipmaker provided strong current-quarter guidance, significantly exceeding analysts’ expectations due to increased demand for its memory chips related to artificial intelligence applications.

• Aramark shares rose 5.5% following reports that French competitor Sodexo was considering a takeover of the food catering company.

• Concentrix experienced an 11% decline after the business process outsourcing firm reported disappointing quarterly earnings and offered weak guidance.

• HB Fuller saw a 10% decrease as the adhesives manufacturer reported third-quarter earnings that did not meet analyst expectations and reduced its full-year guidance.

• Accenture stock rose 4.3% after the professional services firm exceeded quarterly earnings and revenue expectations, although it projected annual revenue below Wall Street estimates.

• CarMax fell by 7% as the used-car retailer’s strong second-quarter sales were insufficient to alleviate challenges in its car-loan business.

• Southwest Airlines shares increased by 4.7% after the airline raised its revenue-per-capacity forecast for the current quarter and announced a $2.5 billion stock repurchase program.

• GE HealthCare stock dropped 1.6% after UBS downgraded the medical technology company’s rating to "sell" from "neutral," citing a difficult-to-justify valuation given its lower growth outlook.

• Sonos saw a 6.3% decline after Morgan Stanley downgraded its rating on the audio equipment manufacturer from "overweight" to "underweight," suggesting the impact of the company’s app redesign may be more significant than currently recognized.
