AI Stocks Face Growing Selling Pressure

Selling pressure is building across artificial intelligence and semiconductor stocks as investors reduce exposure to some of the market's strongest performers. Recent declines in momentum stocks suggest that previously popular trades are losing support, particularly among companies that benefited from the AI investment boom.

Momentum Stocks Lead Market Declines

According to Société Générale, the sharpest losses have been concentrated among stocks with the strongest performance over the past year.

The bank's analysis of the MSCI World index highlights the extent of the correction:

Top 5% of performers: Declined approximately 20% last week.
Next 5% of performers: Recorded smaller losses.
Market impact: Selling remained concentrated in heavily owned stocks rather than spreading evenly across global equities.

This pattern suggests that investors are unwinding crowded positions after an extended period of strong returns.

AI Investment Costs Raise Concerns

AI and semiconductor companies have attracted substantial investment, but attention is shifting toward the financial returns these businesses can generate.

Investors are increasingly questioning whether spending on data centers, computing infrastructure and advanced chips will translate into sufficient revenue growth.

Financing costs and profitability expectations have become particularly important. As confidence weakens, investors taking profits from earlier gains can add further pressure to share prices.

Market Concentration Increases Volatility

Trading activity is also concentrated among relatively few companies. Within an index containing approximately 2,000 stocks, fewer than 100 account for around 25% of daily dollar trading volume.

Such concentration can accelerate market gains when sentiment improves, but it can also deepen declines when investors move toward safer positions.

AI and semiconductor stocks remain important market themes, although investors are becoming more selective. Companies demonstrating clear earnings potential may attract stronger support than those relying mainly on future growth expectations.

This shift could keep volatility elevated, with sharp movements between periods of renewed AI optimism and broader selling pressure.
