AI Stock Sell-Off Weighs on Futures, But Some AI-Selected Portfolios Outperform

U.S. stock index futures fell in premarket trading on Monday, September 14, as comments from Anthropic CEO Dario Amodei calling to “slow the pace” of AI capability advances triggered a sell-off in semiconductor and AI-infrastructure stocks. The negative sentiment was compounded by a sharp rise in crude oil prices, adding to market volatility.

Market Sentiment Sours on AI Caution

In premarket activity, Nasdaq futures were down approximately 1.65%, while S&P 500 futures traded 0.68% lower, according to Investing.com data. The downturn in technology shares followed Amodei's cautionary remarks, which appeared to unnerve investors who have heavily bid up AI-related equities this year.

Adding to the cautious mood, crude oil prices surged more than 3%, with West Texas Intermediate approaching $103 per barrel. The spike was attributed to a Saudi pipeline remaining offline and the postponement of a key diplomatic meeting concerning the Strait of Hormuz.

AI-Driven Strategies Show Resilience

Despite the broad market weakness, some algorithmically managed stock portfolios have demonstrated notable resilience. An AI-powered strategy from Investing.com, called "Beat the S&P 500," has posted a gain of 4.61% month-to-date, outperforming its S&P 500 benchmark by 4.27 percentage points.

• Top Performer: The leading holding in the "Beat the S&P 500" strategy is Hewlett Packard Enterprise (HPE), which has surged 22.06% since September 1. The gain follows a strong fiscal Q3 earnings report, raised full-year guidance, and a sector-wide rally in AI-server stocks.
• Tech Strength: A technology-focused model, "Tech Titans," is outperforming the S&P 500 by 7.81 percentage points. Its top holdings include Intel (+15.70%), AMD (+12.30%), and Marvell (+12.22%), which have so far held onto gains driven by strong AI-chip demand narratives from earlier in the month.
• Laggards: In contrast, strategies with different focuses are trailing. The "Dominate the Dow" and "Financial Fortresses" portfolios were down 1.82% and 2.89% for the month, respectively, underscoring the market's current preference for specific technology and energy themes.
