The leaderboard

Retail chatter on Friday centered on a mix of chipmakers, space stocks and longtime retail favorites, according to mention-count rankings on a retail trading platform. Micron Technology (NASDAQ:MU) ranked third by mentions. AST SpaceMobile (NASDAQ:ASTS) ranked fourth with 5,692 mentions, and GameStop (NYSE:GME) was fifth with 5,374. Sellas Life Sciences (NASDAQ:SLS) ranked eighth with 4,521 mentions, Trump Media and Technology Group (NASDAQ:DJT) ninth with 4,482, and Applied Digital (NASDAQ:APLD) rounded out the top 10.

Mentions for several of those names were rising compared with prior periods.

Micron and the chip rout

Micron's place near the top of the list reflected one of the day's biggest stories. The memory maker slid on Friday amid worries that China's CXMT is advancing in DRAM technology, as well as broader fears about how AI and so-called neocloud companies will finance their spending. All 30 members of the PHLX Semiconductor Index fell, and the sector extended a long losing streak.

Other memory and storage names also tumbled, including Seagate Technology (NASDAQ:STX), Western Digital (NASDAQ:WDC) and Sandisk (NASDAQ:SNDK). The Nasdaq Composite fell 572.99 points to 26,140.03, capping its worst week since June.

Applied Digital and AI infrastructure

Applied Digital, which develops data centers for AI and high-performance computing, plunged on Friday as AI data-center stocks sold off. It was part of a group that included CoreWeave (NASDAQ:CRWV), IREN (NASDAQ:IREN) and Cipher Digital (NASDAQ:CIFR), all of which dropped sharply. The selling reflected a shift in focus from what AI can do to how it will be financed, according to market commentary.

One market commentator described the divide: "The AI group is now splitting between companies that can fund the buildout themselves and those that have to borrow."

Space stocks and SpaceX buzz

AST SpaceMobile's high ranking came amid heavy retail interest in space companies. SpaceX drew significant retail buzz on Friday, and Evercore ISI raised its price target on the stock to $275 from $230 with an Outperform rating. Elon Musk had posted on X on Oct 15: "Unless there is a major world war, SpaceX probably gets to >$100T in <10 years." SpaceX shares rose early on Friday but slipped by the close, according to market reports.

Tesla (NASDAQ:TSLA) added to the space chatter by unveiling a redesigned Roadster with SpaceX-developed cold-gas thrusters, though its shares reversed an early rally and closed lower.

GameStop and Trump Media are perennial retail favorites, and both appeared in the top 10 without a specific catalyst reported in the rankings. Sellas Life Sciences, a clinical-stage biotech, also drew heavy attention, though no specific news was cited. Smaller biotech stocks broadly fell on Friday as long-term Treasury yields stayed elevated.

The broader market backdrop was cautious. The S&P 500 fell 84.62 points to 7,659.44, the VIX rose to 19.99, and the Fear & Greed Index stood at 30, in "Fear" territory. The AAII sentiment survey showed bears outnumbering bulls.

Earnings Calendar for Retail Favorites

The Federal Reserve announces its next decision on Oct 28. Big technology earnings arrive next week. Netflix (NASDAQ:NFLX) reports on Tuesday, and Tesla and Meta (NASDAQ:META) report on Wednesday. Western Digital reports Thursday, giving another read on the memory market after Micron's slide.
