US midday market brief: Dow drops 700 points as inflation fears return

The market’s midday message on Friday was blunt: this selloff isn’t just about one bad tape, it’s about two worries that can linger for months.

The Dow Jones Industrial Average was down 715 points, or 1.5%, while the S&P 500 fell 1.1% and the Nasdaq slid 1.4%, pushing all three benchmarks into the red for the month of February.

With Friday's slump, the Nasdaq is on track for its weakest month since March last year.

The inflation print that reset rate bets

The first shock was inflation, which originated from the “upstream” part of the pipeline.

January’s Producer Price Index (PPI) rose 0.5% month-on-month versus 0.3% expected, and the core reading (which strips out food and energy) jumped 0.8%.

The pace immediately forces investors to rethink how quickly price pressures are cooling.

Why does that matter for stocks? Because some PPI components feed into the PCE price index, the Federal Reserve’s preferred inflation gauge.

If economists are right that core PCE could run as hot as 0.5% for January, the year-on-year core PCE rate could drift back up toward 3.1%–3.2%, uncomfortably above the Fed’s 2% target.

The market response was fast: expectations for rate cuts got pushed out.

Traders are now leaning toward roughly two quarter-point cuts for all of 2026, with the March 17–18 FOMC meeting increasingly priced for a hold around 3.50%–3.75%.

For high-growth stocks, where a lot of the value sits in profits expected years from now, “higher for longer” rates tend to hurt because future earnings get discounted more aggressively.

The AI fear that hit beyond one stock

The second force was more psychological, but arguably more structural: a creeping fear that AI isn’t just boosting a few winners, it’s also forcing layoffs and margin resets across the rest of corporate America.

Block’s announcement that it is cutting nearly 4,000 employees, alongside public comments from co-founder Jack Dorsey suggesting many companies could face similar restructurings within a year.

The developments landed like a warning shot rather than a confidence booster.

Investors didn’t treat it as a simple “efficiency” story. They treated it as evidence that cost pressure, competition, and automation are converging at the same time.

Tech took the brunt. Salesforce fell more than 4%, Microsoft lost about 2%, and cybersecurity name Zscaler plunged 11% after missing on deferred revenue.

In the AI supply chain, CoreWeave dropped 16% on disappointing guidance, while Nvidia extended Thursday’s post-earnings weakness with another 2% slide.

The unresolved question over the weekend isn’t whether Friday was “overdone.”

It’s whether inflation and AI disruption are starting to re-price the same thing: what investors should be willing to pay for growth when the cost of money stays high, and the rules of white-collar work are shifting in real time.
