Stocks making the biggest moves premarket: Broadcom, Micron, Petco, Coinbase and more

Broadcom tumbled 15% after fiscal Q2 revenue of $22.19B missed the $22.27B consensus, with infrastructure revenue also coming in below estimates at $7.18B versus $7.32B. The weak print pressured AI semiconductor peers, while several other names moved on earnings or guidance: CrowdStrike fell 10% on soft Q2 guidance, PVH dropped 22% after reiterating full-year EPS guidance, and UnitedHealth and Medtronic rose on analyst upgrades. Crypto-linked stocks also weakened as Bitcoin fell about 5%, with Robinhood down nearly 2%, Coinbase off 1%, and Strategy down 2.7%.

Analysis

The market is treating Broadcom as a read-through on AI infrastructure spend, but the more important signal is that the burden of proof has shifted from demand narrative to execution quality. When a franchise with diversified cash generation misses by a hair, the sector tends to de-rate first on margin/ordering fear rather than on the headline miss itself; that makes the move in MU, AMD, and SMCI more about portfolio de-grossing than company-specific fundamentals. Near term, the risk is not an AI capex collapse but a multiple reset if hyperscalers push out purchases by even one quarter, which would pressure the entire semi complex for weeks.

Cybersecurity is behaving similarly: the issue is not that spending disappears, but that buyers are increasingly forcing proof of consumption before renewing or expanding. CRWD’s guide leaves room for a second-order hit to PANW and FTNT if channel checks show elongating deal cycles, because the market will assume large-platform consolidation can delay multi-point growth for smaller vendors. The setup favors a transient air pocket over a secular turn, but that still matters because these names trade on forward growth durability rather than absolute earnings.

On the consumer side, FIVE’s reaction suggests the market is discounting that strong traffic can be temporary if basket expansion is weak; that creates a better setup for a pair trade versus discretionary peers where share gains are still plausible. PVH looks like the more structural loser because reiterated guidance in a promotional environment usually means margin defense is already underway, which can compress estimates for multiple quarters even if revenue stabilizes. In contrast, UNH and MDT have a cleaner path to upside because both are benefiting from improving estimate credibility rather than a new fundamental inflection; those are the kinds of names that attract defensive reallocations when growth trades wobble.

Key Decisions for Investors

• Short AVGO / long XLK or SOXX for 1-3 weeks: use the sector de-rating as a cleaner way to express AI capex uncertainty, with downside capped if the market quickly treats the miss as idiosyncratic.
• Buy PANW and FTNT on a staggered basis over the next 5-10 trading days only if they underperform CRWD by another 2-3%; the trade is for a sympathy flush, not immediate momentum, with a 1-2 month rebound window.
• Pair long UNH / short a basket of high-multiple growth defensives for 1-2 months: the upgrade flow supports relative outperformance while the market is rewarding estimate revisions over narrative.
• Short PVH versus long FIVE for 2-6 weeks: FIVE has operating momentum despite the selloff, while PVH’s guidance posture suggests slower margin recovery; use a market-neutral structure to isolate execution divergence.
• Avoid catching SMCI, AMD, and MU until the next hyperscaler capex data point; if semis gap lower again on the open, consider buying short-dated puts on SOXX rather than single names for better event-risk control.
