Last week’s sharp volatility in U.S. stocks—was it the start of a storm or a buying opportunity? Wall Street strategists believe it was more about profit-taking rather than a fundamental breakdown, with the long-term AI narrative far from over.

The tech-heavy Nasdaq saw significant swings as investors pulled out of this year’s AI darlings, tempered expectations for a December rate cut, and reassessed the U.S. economic outlook after the longest government shutdown in history ended.

Despite the steepest one-month decline, analysts argue the sell-off was driven by profit-taking and shutdown-induced jitters, not a collapse in AI fundamentals or corporate earnings.

Jeff Krumpelman, Chief Investment Strategist and Head of Equities at Mariner Wealth Advisors, advised long-term AI investors not to panic. “We’re in the ‘stay the course’ camp,” he explained, noting his team built substantial positions in stocks like NVIDIA (NVDA) during the 2022 downturn but has since trimmed exposure to avoid overconcentration.

Krumpelman emphasized that AI’s early adoption remains a robust multi-year theme, dismissing comparisons to the dot-com bubble. “This is real,” he said. “We’re in the early innings of AI, and it’s tangible. This isn’t 2000.”

He added that the pullback revealed opportunities beyond megacaps, with lagging software firms like ServiceNow now looking attractive. “Some cybersecurity names outside the ‘Magnificent Seven’ also offer compelling value,” he noted.

**Simple Math Behind the Sell-Off** Alex Morris, CEO and CIO of F/m Investments, acknowledged AI as the market’s strongest long-term driver but attributed last week’s sell-off to technical factors. “It’s basic math,” he told Yahoo Finance. “AI stocks are heavily weighted in indices. When they wobble, the market overreacts.”

Morris highlighted profit-taking and positioning adjustments ahead of earnings as key catalysts, especially with sky-high expectations. “Even strong earnings can disappoint when priced to perfection,” he said, noting the outsized impact of top-heavy stocks on indices.

**Earnings Resilience Supports Market** Corporate profits have so far upheld market resilience. Barclays strategist Venu Krishna noted S&P 500 Q3 2025 net margins hit a 25-year high of 14.2%, with 82% of companies beating EPS estimates and a 13.1% blended earnings growth rate—marking a fourth straight quarter of double-digit expansion.

Growth wasn’t confined to tech giants: nine of 11 S&P sectors posted year-over-year earnings growth, and 76% of firms surpassed revenue forecasts.

The next major test? NVIDIA’s upcoming earnings, which will determine whether recent turbulence signals a deeper correction or another “stay the course” moment.
