Stocks making the biggest moves midday: Apple, Palantir, Nvidia, Coinbase, Bloom Energy & more

Midday trading was mixed: Fiserv rose 12% after adjusted EPS of $1.75 beat the $1.72 consensus and it authorized a $500 million fourth-quarter buyback, while Revvity gained 11% after raising its full-year adjusted EPS guidance to $5.40–$5.45. DuPont climbed about 9% after beating estimates and lifting its outlook, but Shopify fell more than 5% after missing estimates on subscription gross profit and GMV, and Thomson Reuters dropped 7.5% after adjusted EPS missed. AI-linked stocks rebounded, with Nvidia up 3% and AMD up 5%; several other stocks moved sharply following earnings, guidance, or analyst-rating changes.

Analysis

The useful signal is dispersion in earnings quality, not the broad AI bounce. In this tape, gross-margin and demand indicators are being priced more harshly than small EPS/revenue beats: that raises the bar for companies whose growth requires operating leverage. For Shopify (SHOP), weaker subscription gross profit and GMV leave less room to absorb investment or mix pressure; the low-thirties outlook is not an unambiguous guide-down, so verify the actual range and cash conversion before pressing a short. Zebra (ZBRA) is a cleaner margin watch: a material gross-margin miss despite top- and bottom-line beats may indicate mix or cost pressure, but one quarter alone does not establish persistence.

Conversely, DuPont (DD) and Revvity (RVTY) have raised outlooks, giving their beats a more credible forward component; follow-through in organic growth and guidance conversion matters more than the initial gap-up. Fiserv’s (FISV) buyback is a marginal demand signal, not evidence that earnings durability has improved. The AI-linked rebound is positioning relief, not fresh fundamental confirmation; chasing it risks buying a factor squeeze before estimates stabilize.

Over the next 1–3 months, monitor SHOP GMV/subscription gross profit, ZBRA gross margin, and DD/RVTY guidance realization. Over 6–18 months, sustained AI infrastructure spending could benefit NVDA, AMD, NBIS and IREN, but capital intensity and customer funding economics are key missing checks. The contrarian risk is treating every beat as bullish or every post-earnings decline as a broken thesis; Gartner’s (IT) selloff despite a beat particularly warrants checking the details behind guidance and demand before inferring a durable downgrade.

Key Decisions for Investors

• Avoid chasing the one-day AI bounce in NVDA, AMD, SNDK, NBIS and IREN; wait for estimate revisions or evidence that demand is converting into cash flow. Falsifier: sustained upward revisions across the group rather than price-only recovery.
• Consider a tactical ZBRA short only if subsequent commentary or results confirm margin pressure; cover if gross margin stabilizes or demand/mix improves. The current quarter alone is insufficient to establish a durable downside trend.
• Keep SHOP on a conditional short/watch list, not an automatic post-miss short: verify the precise fourth-quarter growth range, GMV trajectory and subscription gross-profit trend. A range at or above expectations with stable cash conversion would weaken the thesis.
• Favor DD and RVTY on pullbacks over chasing their earnings reactions, contingent on next-quarter organic growth and guidance conversion; failure to sustain the raised outlook invalidates the relative-quality case.
