Here are Thursday's biggest analyst calls: SpaceX, Nvidia, First Solar, Nike, JetBlue, Cisco, Cinemark & more

Wall Street analysts issued a mixed slate of rating changes, with upgrades for companies including Astera Labs, JetBlue, Frontier, Procore, and First Solar, alongside downgrades for Cisco, Dollar Tree, and Nike. Trex was upgraded after Q3 adjusted EBITDA of $100M beat the firm’s and Street’s $91M estimates, revenue beat by 15%, and the company raised FY26 guidance; its price target rose to $65 from $46. The calls may affect individual stocks, but the article reports no share-price reactions.

Analysis

This is a broker-opinion roundup, not a single new information event: most calls offer little independently verifiable evidence of a change in cash flows. Avoid treating the broad positive skew as a sector signal. The clearest near-term fundamental delta is TREX, where reported results and raised guidance provide a checkable catalyst; however, the higher valuation framework raises the bar for follow-through. Watch subsequent demand, pricing and margin commentary rather than extrapolating one quarter’s beat.

AI infrastructure calls point to a second-order dispersion trade, not a blanket buy. ALAB’s connectivity exposure and the Lumentum/MRVL/NVDA strategic narrative may attract flows, but potential acquisition interest in Lumentum is speculation, not a catalyst with assured value. Conversely, CSCO’s cited cloud growth could coexist with weaker incremental economics if pricing pull-forward and cloud margins disappoint. The key test is realized growth and profitability, not thematic exposure.

NKE’s downgrade highlights a potentially slower-moving inventory and China reset; near-term sentiment can worsen before operating results establish a floor. Positive airline calls are especially sensitive to fuel, fares and capacity, none of which are quantified here. Across the list, the main contrarian point is that rating changes can amplify crowded positioning without changing estimates. The roundup alone does not justify broad exposure; prioritize names with measurable earnings or guidance evidence and require confirmation from filings and upcoming results.

Key Decisions for Investors

• Conditional long TREX on evidence that raised FY26 guidance is supported by sustained demand and margins; stage entry rather than chase the rating-driven move. Reassess if guidance is cut or follow-up results fail to convert revenue growth into EBITDA. The raised valuation multiple makes disappointment asymmetric.
• Tactical short/underweight NKE only if channel checks or company commentary confirm persistent markdowns and weak China/Running trends; use the next earnings update as the key catalyst. Cover if inventory clears without deeper discounting or guidance stabilizes. The broker call itself is not confirmation.
• Keep CSCO underweight versus a diversified AI-infrastructure exposure only if cloud growth fails to translate into acceptable margins or pricing pull-forward weighs on orders. Verify cloud-business profitability and demand cadence; a durable growth/margin combination would falsify the relative-value thesis.
• Do not buy LITE on takeover speculation or treat NVDA as a likely acquirer. Monitor transaction disclosures and independent operating updates; absent those, acquisition optionality is not a basis for sizing a position.
