Nasdaq drops 1.3% as chips crack before Fed minutes
Published on August 19, 2026
The Nasdaq lost 1.33% on Tuesday and one sector did nearly all the damage. Chip stocks cracked, the SOX index gave up almost 5%, and traders were reminded that the bond market, not artificial intelligence, is running this tape. The Fed minutes land tonight and can reset the whole thing.
Chip stocks dragged the Nasdaq down
At Tuesday's close the Nasdaq Composite sat at 26,289.71 (-1.33%), the S&P 500 at 7,691.76 (-0.69%) and the Dow at 53,343.40 (-0.22%). The gap between the three tells the story. This was not a broad sell-off. It was a sell-off in expensive tech.
The Philadelphia Semiconductor Index fell 4.98% with all thirty members lower. Memory names took the worst of it: SK Hynix -9.2%, SanDisk -9.0%, Micron -7.0%. Nvidia held its loss to -2.3% and Apple actually closed up 1.5%. Investors did not dump technology. They dumped the profits that sit furthest out in time.
Long yields are calling the shots
The US 10 year yield climbed to 4.75%, its highest since January 2025. The 30 year touched 5.33%, a level last seen in 2007. For a company whose earnings arrive a decade from now, every basis point hurts twice. Valuations compress and the cost of funding new fabs goes up.
Kevin Gordon, head of macro research at Charles Schwab, put it plainly: inflation is in the driver's seat for stocks. He points out that the correlation between yields and equities is the most negative since 1997, a sign the bond market is trading prices rather than growth.
Oil keeps the pressure on. Brent pushed toward $92, a fourth straight gain, with Washington and Tehran still deadlocked over the Strait of Hormuz. Costlier energy means stickier inflation, which means long yields that refuse to fall. Tokyo got the message overnight and the Nikkei dropped 3.12%.
Crowded positioning did the rest
Bank of America's August fund manager survey, reported by Benzinga, shows cash down to 3.5% of assets and a net 56% overweight in equities, the highest since November 2021. The firm's own sell signal is triggered, and Michael Hartnett is telling clients to trim rather than add. One more number stands out: 32% of managers name the AI bubble as the biggest threat while staying long it.
When everyone leans the same way, a 5.33% long bond is enough to clear the room. The VIX was still at 14.2 on Monday, its lowest reading of the year.
Key levels today
| Instrument | Level (support / resistance) | Change (Aug 18 session) | Scenario to watch |
|---|---|---|---|
| S&P 500 | Support 7,690 then 7,568, resistance 7,770 and 7,800 | -0.69% | A close below 7,690 opens 7,568. Above 7,770 the record at 7,799 comes back into play |
| Nasdaq 100 | Resistance 30,000, record high 30,600 | -1.70% | The September contract trades 29,472. While the index stays under 30,000 tech keeps a ceiling |
| US 30 year yield | Pivot zone 5.25% / 5.35%, highest since 2007 | +2 basis points | Above 5.35% chips get another leg down. Back under 5.25% and tech breathes |
| Brent | Support $89, resistance $92 | +0.42% | A clean break above $92 revives the inflation premium and weighs on indices |
Economic calendar
2:00 pm ET, FOMC minutes. The committee held rates at 3.50% to 3.75% on July 29 with three dissents in favour of a hike, according to Newsquawk. If more members were ready to join them, the 10 year targets 4.80% and the Nasdaq breaks its lows. A conditional tone lets the market exhale.
10:30 am ET, US crude inventories. Another draw after last week's 328,000 barrel drop would push Brent above $92.
Thursday, weekly jobless claims. US payrolls fell by 23,000 in July. A jump in claims would pull long yields down and give tech some relief.
Friday, flash PMIs. A composite above 53 keeps a rate hike on the table heading into Jackson Hole, running August 27 to 29.
The bottom line
The Nasdaq is paying for higher long yields, not for weaker chip demand. While the 30 year holds above 5.25%, every tech bounce stays fragile.
