STOCK BUBBLES

US market on August 27, 2026: 390 up, 559 down, Okta leads

The session closed without a clear winner: 390 of 982 stocks higher, 559 lower and 33 flat, a ratio of 0.70 to one. Weighted by market capitalisation the whole set moved +0.7%, while the median stock fell 0.4% — the two point different ways, so the largest companies carried the reading against the crowd.

59 stocks moved more than 5% — 51 up, 8 down — and 15 of those cleared 10%. 32 names closed at a fresh twelve-month high and 10 at a twelve-month low. Total turnover across the set came to $613.5bn.

Okta led the session at +28.6%, closing on $172.91, ahead of Salesforce at +22.6% on $252.05, CrowdStrike Holdings at +20.5% on $227.96. The other end belonged to Everpure at -8.9% on $99.24, BURLINGTON STORES at -7.6% on $290.00, Sprouts Farmers Market at -6.7% on $81.04.

By sector, strongest to weakest: Technology +3.7%, Materials -0.1%, Energy -0.3%, Communication -0.5%, Financials -0.5%, Industrials -0.6%, Utilities -0.7%, Real Estate -0.9%, Healthcare -1.0%, Consumer -1.1%. The spread between the best and the worst reading came to 4.8 points, with 156 companies in Technology and 154 in Consumer.

1 of the 10 sectors finished higher, covering 156 of the companies here; the 9 that fell hold 826. The decline reached almost every corner of the market rather than one sector alone.

Money concentrated in Nvidia ($68.1bn), Micron Technology ($27.0bn), Microsoft ($14.5bn) — together 17.9% of everything traded across 982 companies.

Against their own thirty-day averages, turnover stood out in Okta (5.9×), Jazz Pharmaceuticals (5.9×), BURLINGTON STORES (4.8×).

Reporting next session: BJs Wholesale Club Holdings, Dick's Sporting Goods, HEICO, Intuit, Semtech. None of them had reported as of this close, so nothing above reflects their figures.

All figures are daily closing bars for the 982 companies in the set, measured against the previous close. The running session is never included.
