STOCK BUBBLES

US market on September 14, 2026: 485 up, 476 down, Zscaler leads

The session closed without a clear winner: 485 of 979 stocks higher, 476 lower and 18 flat, a ratio of 1.02 to one. Weighted by market capitalisation the whole set moved -0.4%, while the median stock rose 0.0% — the two point different ways, so the largest companies carried the reading against the crowd.

164 stocks moved more than 5% — 54 up, 110 down — and 35 of those cleared 10%. 16 names closed at a fresh twelve-month high and 28 at a twelve-month low. Total turnover across the set came to $598.9bn.

Zscaler led the session at +16.5%, closing on $191.73, ahead of Tenable at +16.5% on $35.08, Rubrik at +15.6% on $100.20. The other end belonged to Corning at -13.7% on $143.60, Teradyne at -13.3% on $329.20, MaxLinear at -13.1% on $64.79.

By sector, strongest to weakest: Communication +1.6%, Healthcare +1.4%, Consumer +0.1%, Financials -0.3%, Real Estate -0.7%, Energy -0.7%, Technology -1.4%, Utilities -1.4%, Materials -1.6%, Industrials -2.0%. The spread between the best and the worst reading came to 3.6 points, with 46 companies in Communication and 201 in Industrials.

3 of the 10 sectors finished higher, covering 325 of the companies here; the 7 that fell hold 654. Communication and Industrials pulled hardest in opposite directions.

Money concentrated in Nvidia ($27.9bn), Micron Technology ($25.1bn), Sandisk ($14.9bn) — together 11.3% of everything traded across 979 companies.

Against their own thirty-day averages, turnover stood out in Cenovus Energy (2.9×), Tenable (2.8×), SPX Technologies (2.7×).

Reporting next session: Casey's General Stores, GameStop, AeroVironment, Chewy, Core & Main. None of them had reported as of this close, so nothing above reflects their figures.
