The Midday Tape

Stocks are sliding into the last trading day of October with tech doing most of the damage, even as a packed earnings slate delivers plenty of individual winners.

The broad tape is risk-off, and growth is leading the retreat.

The S&P code (SPY) is down 1.5% and the Russell small-cap proxy (IWM) is off 1.6%, but it's the Nasdaq-100 (QQQ) that's taking the real hit, down 3% on the session. Gold (GLD) is getting hit even harder, down 3.1% in a sharp reversal, while oil (USO) catches a bid, up 1.2%. Treasuries (TLT) and the dollar (UUP) are essentially flat. This is broad de-risking, not a single-sector rotation story, with month-end flows likely adding to the chop.

AI infrastructure demand is colliding with tariff math.

Caterpillar (CAT) is the session's most telling conflict: orders are "soaring" on AI-driven power demand, per the morning's reporting, but tariffs are offsetting the enthusiasm, and the stock is down 2.1% even as Oppenheimer holds an Outperform rating and a $1009 price target. It's a reminder that strong end-demand stories aren't immune to margin pressure. Elsewhere in AI, SentinelOne (S) is integrating Anthropic's Claude into its Wayfinder platform, and Tenable (TENB) and Qualys (QLYS) both rolled out AppViewX integrations, incremental security-AI tie-ups rather than market-moving events.

Earnings reactions are scattered and instructive.

Laureate Education (LAUR) is the biggest single-name loser, down 6.2% despite reaffirming full-year guidance, a sign the market wanted more than an in-line reaffirm. MGM Resorts (MGM) is doing the opposite, up 3.1% even as both JPMorgan and Barclays trimmed price targets, suggesting the print itself is being read better than the sell-side reaction implies. Biogen (BIIB) is up 1.5% on a split verdict from analysts, Wedbush cutting its target to $225 while RBC lifted its to $272. Allied Gold (AAUC) is down 3.6%, compounding the broader bullion rout after an operational update on its Kurmuk mine. Acadian Asset Management (AAMI) slipped 1.8% on its Q3 print, and V.F. Corp (VFC) is roughly flat after BNP upgraded shares to Neutral. On the corporate action front, ADT (ADT) is being acquired by Thrive Holdings in an all-cash deal, though the stock is barely moved on the news. Saia (SAIA) is flat despite announcing a fresh $250 million buyback alongside its results, while Crocs, Oshkosh, PHINIA and Entegris all posted results with raised or maintained guidance, underscoring that the earnings tape itself is far from uniformly weak.

Still ahead this afternoon:

month-end rebalancing flows are in play given today closes out October, and the market still has to digest reaction to the dozens of other reports that landed before the bell, from Avery Dennison to Hyatt to Ameriprise, as traders sort the real guidance changes from the noise.

Bottom line: the index tape says risk-off, but underneath it the dispersion between earnings winners and losers is wide, and month-end flows are likely amplifying moves that otherwise would have stayed contained.
