Stocks making the biggest moves midday: Abbott Labs, AMD, Charles Schwab, On Semi & more

Midday trading was driven by a mix of analyst upgrades, earnings beats, and guidance disappointments: AMD rose more than 7% after Bernstein lifted its target to $265, while Abbott fell nearly 7% on weak Q2 and full-year EPS guidance. Notable movers included Aehr Test Systems (+11%) on a $41 million AI-related order, J.B. Hunt (+8%) on a top- and bottom-line beat, and Charles Schwab (-5%) after revenue missed estimates despite stronger adjusted earnings. The tape was broadly stock-specific, with several names moving 3% to 9% on earnings, guidance, or analyst actions.

Analysis

The cleanest read-through is that semis are still trading more on supply-chain positioning than on headline beats. AMD and INTC rallying together suggests investors are re-rating server CPU share capture and foundry/packaging leverage, but the second-order winner may be the broader AI infrastructure stack: if hyperscalers keep re-accelerating capex, the incremental beneficiaries are the vendors that convert design wins into volume fastest, not necessarily the highest-ASP names. That also explains why AEHR’s order matters more as a signal than as absolute revenue — it validates that AI-related test/qualification spend is still expanding deeper into the ecosystem.

The semiconductor move is not uniform. TSM’s dip despite a beat points to a market that has already priced the “obvious” earnings strength, while the better asymmetry may sit in names with operating leverage to a second-half utilization recovery such as ON and, to a lesser extent, LITE/COHR via optical interconnect spend. If AI capex is re-accelerating, the likely laggard relative to the group is not the foundry but the suppliers that are still waiting for procurement conversion; the risk is that this becomes a crowded momentum trade and any guidance miss or export-control headline could unwind 5-10% quickly.

Outside tech, the most important signal is margin pass-through behavior. PPG’s pricing action implies cost inflation is re-emerging across industrial supply chains, which is supportive for firms with sticky pricing but problematic for transportation and lower-quality consumer names if demand softens. JBHT’s beat suggests freight may be stabilizing, but SCHW’s weaker top line plus product expansion into crypto trading points to a management team trying to offset revenue pressure with new monetization channels — that is not an earnings fix, it is an optionality story over quarters, not days.

Key Decisions for Investors

• Long ON vs short TSM for 4-8 weeks: ON has more room for multiple expansion on AI/industrial recovery, while TSM looks like a consensus-quality hold with less incremental upside. Target ~8-12% relative outperformance; cut if semiconductor leadership rotates away from U.S. suppliers.
• Add AMD on weakness, but hedge with a short INTC call spread if you want to isolate AI server share gains over the next 1-2 quarters. AMD is the cleaner operating-leverage trade, while INTC remains a lower-conviction turnaround with higher execution risk.
• Buy a basket of AEHR/LITE/COHR on a 1-3 week horizon as a momentum-follow-through trade tied to AI infrastructure capex. Keep size small: these names can gap 10%+ on order flow, but they also reverse quickly if hyperscaler commentary cools.
• Short ABT on any post-earnings bounce for a 1-2 month trade: the reset in expectations can take another leg lower if the market starts marking down 2026 growth. Risk/reward is favorable to the downside until management proves the guide is conservative rather than structural.
• Pair long JBHT / short SCHW for a 2-4 quarter relative-value expression: JBHT benefits from cyclical freight stabilization, while SCHW faces a slower path to revenue acceleration despite product expansion. Use a tight stop if rate expectations fall sharply.
