• Nasdaq-100 futures drop about 1.03% in pre-market trading, signaling a sharp reduction in risk appetite for growth and technology shares.
  • The selloff is driven by higher oil prices amid U.S.–Iran tensions, rising Treasury yields, and a market reassessment of Fed rate-hike odds.
  • Semiconductor and AI-infrastructure names like Marvell (MRVL), Western Digital (WDC), and Micron (MU) are particularly weak, highlighting the index's concentration risk.

Risk-Off Mood Hits Growth Stocks

Nasdaq-100 futures extended losses early Thursday, last down about 1.03%, as a confluence of geopolitical and macro pressures prompted investors to pare exposure to high-flying technology shares. The move is broad-based, not company-specific, reflecting a shift in sentiment rather than an earnings shock.

The backdrop is a familiar one: oil prices have climbed on renewed U.S.–Iran hostilities, raising concerns about supply disruptions through the Strait of Hormuz. Meanwhile, the 10-year Treasury yield hovers near 4.76%, a level that pressures valuations for companies with profits expected far in the future. Add to that a market-implied 65% probability of a September rate hike, up from 36% before hawkish remarks attributed to Fed Chair Kevin Warsh, and the stage is set for a tech-led selloff.

Chips and AI Infrastructure Bear the Brunt

The weakness is concentrated in semiconductor and AI-related names. Recent market coverage identified notable declines in Sandisk (SNDK), Marvell, Western Digital, Micron, and Seagate (STX). These stocks have been central to earnings expectations and index performance, so when financing costs rise or outlooks disappoint, the Nasdaq-100 can fall more quickly than value-oriented indexes.

"The market is repricing the risk that the Fed might have to stay restrictive for longer," said one trader, speaking on condition of anonymity. "And with oil spiking, it's a double whammy for growth stocks."

Data and Policy in Focus

Today's July JOLTS job-openings report, due at 10:00 a.m. ET, and Friday's August employment report will be key catalysts. Strong data could reinforce rate concerns; weak data might ease policy pressure but revive growth worries. The next FOMC meeting is set for September 15–16.

Beyond the macro data, trade frictions add another layer. Late-August reports indicated U.S.–Canada trade talks collapsed, with the U.S. imposing a 50% tariff on roughly $20 billion of Canadian goods and Canada planning retaliation on September 8. While not the primary driver of today's futures move, such uncertainties can raise input costs and disrupt supply chains.

What to Watch

Short-term volatility is likely to persist through Friday's jobs report. A prolonged Middle East escalation that keeps crude elevated, combined with resilient labor data, could push yields higher and weigh further on expensive growth equities. Conversely, if oil retreats and data comes in soft-but-orderly, tech shares could stabilize quickly.

Historical context offers some perspective: September has been Wall Street's weakest month, with the Nasdaq averaging a 1% decline since 1971. But seasonality is a tendency, not a rule.

As one portfolio manager put it, "The market is caught between inflation worries and growth concerns. Until we get clarity on the Fed and oil, expect choppy trading."

Correction: An earlier version of this article misstated the timing of the FOMC meeting. The correct dates are September 15–16.
