Micron Technology (MU), AST SpaceMobile (ASTS), and Adobe (ADBE) all declined in premarket trading Tuesday as a wave of negative catalysts hit each stock simultaneously.
Micron shares fell more than 2.7% before the opening bell, extending a steep 3.9% decline from the prior session, rattling investors already on edge about competition from China.
The selloff followed reports that China’s ChangXin Memory Technologies, known as CXMT, was developing a new server-memory cell architecture referred to as “4F square.”
Tesla and SpaceX CEO Elon Musk also made comments about advances in Chinese memory chips, adding further pressure to Micron’s already struggling share price.
Retail traders on Stocktwits reflected the bearish mood, with one user saying, “100% going to drop 50$ opening,” capturing the anxiety surrounding the stock.
Micron’s retail sentiment on Stocktwits was rated “neutral” while message volume was classified as “high,” even as the stock has surged over 250% year-to-date.
AST SpaceMobile dropped 3.5% in premarket trading after Piper Sandler downgraded the stock to “Neutral” from “Overweight” and slashed its price target to $54 from $98.
Piper Sandler cited lower confidence in the company’s satellite launch pace in 2026 and 2027, pointing to uncertainty around timelines as a core reason for the rating cut.
The brokerage also highlighted SpaceX’s decision to purchase mobile spectrum for $8 billion, noting that if SpaceX sought to disadvantage mobile network operators, it could limit launch availability for partners such as AST SpaceMobile.
ASTS shares have fallen 27% year-to-date, and retail sentiment on Stocktwits remained “bullish” despite the downgrade, with message volume reaching “extremely high” levels.
Adobe fell 1.4% in premarket trading after HSBC downgraded the stock to “Hold” from “Buy” and lowered its price target to $267 from $310.
HSBC highlighted media reports that ArtCraft had released a free, open-source, “auto-coded” clone of Adobe’s Creative Cloud suite, which reportedly includes versions of Photoshop, Illustrator, Premiere, Lightroom, Acrobat, After Effects, and InDesign.
ArtCraft has said it aims to achieve “100% feature parity” with Adobe’s software within a month, a claim that introduced significant headline risk for the company.
HSBC lowered its earnings estimates to account for the risk that some amateur retail users could move away from Adobe’s products as the free alternative gains traction.
Adobe shares are down nearly 33% since the start of the year, with Stocktwits showing “neutral” sentiment and “high” message volume for the stock heading into Tuesday’s session.
