Micron slumps on report Samsung’s new memory chip passed Nvidia’s reliability tests

Shares of Micron are getting slammed on Wednesday after Seoul Economic Daily reported that Samsung Electronics’ new memory chip “passed reliability testing” from Nvidia and is poised to enter the preproduction stage.

Per SE Daily, these HBM4 chips would be used in Nvidia’s Rubin architecture, the successor to Blackwell.

Micron has been significantly expanding its market share in the high-bandwidth memory chip market at Samsung’s expense, and the South Korean company’s renewed progress — with Nvidia’s blessing — threatens to eat away at some of that.

AST SpaceMobile rises after favorable commentary from BofA

Mobile-services-from-space play — and retail investor favorite — AST SpaceMobile rose after receiving a target price upgrade from Bank of America analysts.

In a note published Thursday, BofA telecom services analysts lifted their price target for the stock to $100 from $85, while noting that the low-Earth orbit satellite industry — which supercharged stocks like Rocket Lab, Planet Labs, and AST in 2025 — is set to gain more attention this year:

“We expect the momentum to intensify in 2026 as providers like ASTS and Starlink jockey to offer full cellular service and capture subscribers. Debates will likely grow regarding Starlink’s plans to offer full cellular service and regulatory decisions on Ligado and EchoStar spectrum transactions are events to watch. Carrier partnerships could evolve and pricing and plan decisions should be clearer by year end as ASTS approaches full constellation operability.”

Still, they maintained their “neutral” rating on the stock, saying they “await progress on ASTS 1) fully producing and subsequently launching its BlueBird satellite constellation, 2) successfully operating the constellation, and 3) capturing subscribers and turning them into revenue paying subscribers before becoming more constructive on the story.”

The market has been less reticent: the money-losing company’s shares are up approximately 300% over the last year.

Bulls pour into Joby and Archer options as Trump’s push for record defense budget boosts eVTOL names

Options traders appear bullish on electric aircraft makers like Archer Aviation and Joby Aviation on Thursday, with large volumes boosting the stocks following President Trump’s call for a record $1.5 trillion US military budget for 2027.

Both companies, as well as newly public rival Beta Technologies, have sizable defense contracts. In July, Archer CEO Adam Goldstein told Sherwood News that he believes the company’s defense side will outpace its civil air taxi service for at least a decade.

Traders seem to believe him. As of 10:53 a.m. ET, about 31,000 Archer call options had exchanged hands, around 9,000 short of its 20-day average for a full day. Joby saw roughly 20,000 call options traded by the same time, eclipsing its 20-day average. For the most actively traded calls for Joby and Archer (C$17s expiring February 20 and C$9s expiring on Friday, respectively), volumes on the ask side are outstripping the bid or mid, indicating motivated buyers.
