Premarket is splitting along a single fault line: who benefits from the AI buildout narrative, and who gets caught in the crossfire when that narrative shifts.

Delta Airlines is up on demand momentum, while another insurtech is up on a structural call about self-driving cars, and a rideshare company is up on an autonomous vehicle deal. Meanwhile, two optical component makers are down after a single comment about copper wires at an Nvidia keynote.

An improved acquisition bid is lifting one asset manager, and a single large insider transaction is turning heads in the building products space.

Every modern rocket engine relies on extreme-performance materials. But there’s a limited global supply supporting a rapidly expanding space industry.

Read the full report to see why it matters… and which player might matter most.

Lemonade (LMND): +6%

Morgan Stanley upgraded the insurtech to overweight, pointing to autonomous vehicles as a structural tailwind for its business. The thesis is that as self-driving technology reshapes auto insurance, Lemonade is positioned as an early-stage winner in how those policies get written and priced.

Delta Air Lines (DAL): +4%

Delta raised its first-quarter revenue growth guidance to high single digits, citing accelerating bookings from both leisure and corporate customers into March. The upgrade signals demand momentum is building, not fading, and the market is rewarding the visibility.

Janus Henderson Group (JHG): +2%

Victory Capital Holdings submitted an improved acquisition proposal for the asset manager. An upgraded bid means the acquiring party wants this deal, and that tends to move the target.

Builders FirstSource (BLDR): +2%

A company director bought roughly $4.4 million worth of shares on the open market. Insider buying at that scale, in a single transaction, tends to get the market's attention, and today it did.

Uber (UBER): +3%

Uber and Nvidia announced they will expand their autonomous vehicle partnership to launch a fleet of Nvidia software-driven robotaxis across 28 cities globally by 2028, starting in San Francisco and Los Angeles in 2027. The deal positions Uber's platform as the distribution layer for autonomous vehicles at scale.

Coherent (COHR): -4%

Jensen Huang said at Nvidia's GTC event that copper wires remain important in server racks. For a company that makes optical components for data centers, that is a headwind narrative, and the stock is paying for it.

Lumentum (LITE): -4%

Caught in the same trade as Coherent: Huang's copper wire comments at GTC raised questions about how fast optical interconnects will displace legacy wiring inside AI infrastructure. Lumentum sold off alongside its closest peer.

Honeywell International (HON): -1.5%

CEO Vimal Kapur warned that the U.S.-Iran war in the Middle East could shave a high single-digit percentage off first-quarter revenue, driven by shipping disruptions in the region. He said the impact is transitory and does not alter the full-year outlook, but the market is marking the stock down on the near-term hit.

Semtech (SMTC): -2%

The chipmaker's latest guidance failed to extend its 2026 rally. When a stock has already run hard, the bar for maintaining momentum is high, and Semtech's outlook did not clear it.

Eli Lilly (LLY): -1.1%

HSBC downgraded the pharma giant, arguing the total market for obesity drugs looks inflated and the stock is priced for outcomes that may not materialize. For a name that has been one of the market's biggest winners on GLP-1 enthusiasm, any analyst calling the ceiling gets noticed.

Every modern rocket engine relies on extreme-performance materials. But there’s a limited global supply supporting a rapidly expanding space industry.

SanDisk Corporation (SNDK)

Retail traders on Reddit and WallStreetBets have been circling the memory chip space all week, and SanDisk keeps coming up as the central name. The stock surged more than 25% during the week ending March 13 as investors rushed back in after a Middle East-driven selloff. The stock has soared since then and is now trading at an all-time high of around $712.

The bull case is simple: SanDisk's NAND flash products are effectively sold out through 2026, AI data center demand is pulling in the company's direction, and the stock still trades at a modest multiple given its earnings trajectory. The bear case is equally simple: the stock is up more than 1,100% over the past year, and names that run that fast tend to punish late entries. Whether today's macro headwinds, including renewed oil-driven inflation concerns tied to Middle East tensions, deliver a dip that buyers chase, or mark the start of a more sustained unwind, remains to be seen.

✌️That’s it for today.
