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.

The contrarian setup is in the “good news but not good enough” names: ABT’s guidance reset may already be forcing estimate capitulation, while SCHW and TSM are likely being punished for distribution around high expectations rather than deteriorating fundamentals. Conversely, the market may be underestimating how quickly ON, AMD, and the optical complex can compound if hyperscale AI spending remains even modestly above plan for the next 2-3 quarters.

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.
