The Midday Tape

Stocks are chopping in place at midday as a fresh multi-decade high in long bond yields collides with another wave of eye-popping AI infrastructure spending headlines, leaving the tape torn between a rates scare and a capex boom.

Yields are the story of the session.

The 30-year Treasury touched 5.612%, the highest print since June 2002, and that move is doing damage across risk assets. The iShares 20+ Year Treasury ETF (TLT) is off 0.8%, high yield (HYG) is down 0.4%, and the dollar (UUP) is firmer. The pressure comes as JOLTS job openings printed at 7.079 million and home-price data (Case-Shiller, FHFA) came in soft, muddying the rate-cut debate just as the long end re-prices higher. The S&P (SPY) is down 0.3% and the Russell 2000 (IWM) is off 0.8%, both more sensitive to financing costs than the mega-cap-heavy Nasdaq.

Breadth is the quiet worry under the index-level calm.

A widely circulated breadth read shows the median S&P 500 stock now trading 16% below its 52-week high, the weakest breadth since the dot-com bubble. That is consistent with what the tape shows: headline indexes near flat to slightly lower while the average stock struggles, a market still being carried by a narrow group of leaders.

AI infrastructure spending is that narrow group's fuel today.

Anthropic disclosed compute agreements with SpaceX worth up to $84.5 billion, OpenAI said its B2B revenue has more than doubled in the third quarter with the annualized run rate up over 70% since Q3 began, and Nvidia's (NVDA, +0.7%) buyback is drawing praise from market strategists. SpaceX (SPCX) is up 2.3% on a successful Starship launch and a fresh Buy initiation and $200 target from TD Cowen, which argues the ground-based business is the next leg of the story. Money keeps flowing into the AI supply chain even as the broader market wobbles.

Defense is the session's clearest laggard.

The sector has slipped into a bear market with its longest losing streak on record, dragging names like Lockheed and RTX lower even as Boeing (BA) bucks the group, up 2.1% on a jet delivery to Norwegian Air.

Single-stock action is loud.

Carnival (CCL) is the standout, up nearly 12% after Q3 results and CEO commentary that "vacations are sacrosanct," defying angst about the consumer. Apple (AAPL) is down 2.1% on a Bloomberg report that its new CEO is moving to overhaul the company to run leaner. Netflix (NFLX) is up 2.1%, helped by a new exclusive WWE broadcast deal in Japan. Oil (USO) is down 3% even as Iran links nuclear talks to resolving the Strait of Hormuz standoff, pressured by a US offer of up to 40 million barrels from the strategic reserve. Gold (GLD) is up 0.8% on the geopolitical hedge.

Still ahead this afternoon:

earnings from Concentrix and AAR after the close, continued headline risk out of the Strait of Hormuz, and whether the 30-year yield holds above 5.6% into the bell.

Bottom line: this is a bifurcated tape, rates and breadth flashing caution, AI capex headlines keeping the leaders afloat, and the afternoon will hinge on whether yields keep climbing or give the average stock room to breathe.
