Chips Sell, Software Rallies, and Datadog Claws Back Ground It Lost for No Clear Reason

August 10, 2026 · Indices, Datadog (DDOG), Palo Alto Networks (PANW), American Airlines (AAL), Marvell (MRVL)

U.S. equity indices closed essentially flat on Monday, August 10, masking a sharp rotation underneath. The S&P 500 (SPY) slipped 0.03% to $773.03, the Nasdaq-100 (QQQ) fell 0.30% to $720.87, the Dow (DIA) declined 0.12%, and the Russell 2000 (IWM) fell 0.52%. The semiconductor-tracking SMH fell 2.28% while crude oil (USO) jumped 6.73%, its sharpest one-day move in weeks.

Software and cybersecurity names led the tape while chipmakers lagged broadly — Marvell fell 4.65%, Arm fell 5.21%, Intel fell 4.06%, Nvidia fell 2.86%, and AMD fell 2.86%, while Palo Alto Networks rose 5.82%, CrowdStrike rose 5.01%, Fortinet rose 2.86%, and ServiceNow rose 2.05%. The pattern matches a rotation The Motley Fool flagged two days earlier: money moving out of semiconductor stocks, which have run up sharply in 2026 and grown expensive, and into software names sold off earlier in the year on AI-disruption fears. Palo Alto Networks alone has seen its market value nearly triple over the past year, from roughly $113 billion to nearly $300 billion, according to an August 9 Motley Fool analysis that also flagged the stock's 96x forward-earnings multiple as stretched.

Datadog was the session's largest single mover among names this site tracks, rising 11.48% to $260.78. That's a partial reversal of the 19.03% decline the stock posted on August 6, a drop this site reported at the time as unexplained — no dated news coverage tied it to a specific cause despite Datadog's Q2 2026 earnings landing that same week. As of Monday's close, no new dated news explains the rebound either; Datadog remains roughly 8% below its August 5 pre-decline close of $283.17.

Elsewhere on the tape

American Airlines fell 5.9% to $15.00, the steepest decline among positions this site tracks, as crude oil (USO) rose 6.73% on the same session — a commodity move with no dated news explanation found as of this writing. Marvell Technology, already down roughly a third from its 2026 highs per prior Motley Fool coverage, extended its slide. Uber rose 4.01% and Oracle rose 2.74%, both continuing to trade with the software cohort rather than the hardware one.
