Stocks making the biggest moves after hours: Amazon, Apple, Steel Dynamics and more

Zions reported Q1 net interest income of $662 million, below the $674.5 million StreetAccount estimate, though EPS of $1.56 beat the $1.42 consensus; shares fell almost 3%. Steel Dynamics delivered mixed Q1 results with revenue of $5.20 billion above the $5.10 billion estimate but EPS of $2.78 missing by a penny, while Alaska Air pulled its 2026 forecast and posted a wider-than-expected adjusted loss of $1.68 per share on $3.3 billion in revenue. Amazon rose 3% after agreeing to invest up to $25 billion in Anthropic, and Apple slipped less than 1% after announcing Tim Cook will step down as CEO on Sept. 1.

Analysis

AMZN is the clearest second-order winner: the Anthropic commitment effectively converts a headline AI capex story into a durable AWS demand backlog, which matters more than the equity check itself. The market should view this as evidence that frontier-model training and inference remain structurally bandwidth- and compute-constrained, which supports pricing power for AWS high-margin services and improves utilization across adjacent accelerators, networking, and power infrastructure. The longer-dated implication is that AI spend is becoming less discretionary and more contractual, which is bullish for cloud vendors but also raises the bar for underinvested hyperscalers.

AAPL’s transition risk is not about near-term product execution so much as governance and multiple compression. Insider succession reduces “key-man” shock, but it also removes a premium that comes from Cook’s capital-allocation discipline and operational credibility, especially if iPhone growth stays muted. Over the next 3-12 months, the stock likely trades more on services durability and AI roadmap proof points than on management continuity; absent a clear monetization catalyst, the change can keep a lid on multiple expansion.

For ALK, pulling guidance is a subtle negative because it signals management sees fuel as a swing factor that can overwhelm unit-demand visibility. The risk is that the market starts applying a higher discount rate to all airline earnings power if fuel volatility persists into summer travel season, especially for carriers with less hedging flexibility. STLD looks relatively clean: the miss is small enough that cyclical investors will likely focus on spot steel spreads and volume discipline, but the bigger read-through is that industrials are still operating in a demand environment where beats are hard to monetize unless pricing inflects.

The contrarian view is that AMZN’s rally may be underdone if investors are still treating AI as a software-margin story rather than an infrastructure-annuity story. Conversely, AAPL’s modest decline may be too complacent if the CEO transition becomes the excuse for a broader de-rating in a stock already priced for flawless buyback support. The setup favors owning the beneficiary of committed AI spend and fading the names where visibility is deteriorating, not merely where EPS missed by a penny.

Key Decisions for Investors

• Long AMZN vs. short a basket of large-cap cloud peers over 1-3 months; thesis is that contractual AI demand and capacity buildout will show up first in AWS backlog and utilization, with asymmetric upside if the market re-rates AI infrastructure as recurring rather than cyclical.
• Buy AMZN call spreads 6-9 months out, targeting continuation of AI-driven multiple expansion; risk is limited if the deal is treated as a one-off headline, but payoff improves if subsequent customer announcements confirm a pipeline effect.
• Short ALK on strength for 1-2 quarters or express via put spreads; fuel uncertainty and withdrawn guidance raise the probability of estimate cuts, while upside is capped unless crude and jet fuel retreat materially.
• Stay underweight AAPL for the next 3-6 months until the new CEO proves capital allocation and AI strategy continuity; if using options, consider a collar or put spread into the transition window because governance headlines can compress multiple even without earnings deterioration.
• Hold STLD as a relative-value long vs. weaker industrial cyclicals only if spot pricing stabilizes; otherwise use it as a neutral core position, since the current setup looks more like lack of upside than imminent downside.
