Tech Selloff Deepens on Yields and AI Doubts

The Nasdaq-100 proxy QQQ fell to $684.23 on July 24 from $736.40 four days earlier, with its RSI dropping to 33.1, a level that signals the index is nearing oversold territory under standard technical readings. The Technology Select Sector SPDR Fund, XLK, slipped to $175.88 from $190.52 over the same stretch, while the iShares Semiconductor ETF, SOXX, tumbled to $527.01 from $640.76, underscoring how quickly momentum has reversed across the chip complex.

The broader market tone has also darkened. Adalytica’s S&P 500 trade signals show “Extreme Fear” at 12, while the US dollar and Treasury bond gauges also sit in fear territory, a sign investors are crowding into defensive positioning even as awareness around bonds remains elevated. That backdrop suggests the latest tech drop is not just stock-specific profit-taking, but part of a wider de-risking move.

For investors, the hit lands where market concentration is highest. The largest US technology names carry outsized weight in major indexes and passive funds, so a selloff in a handful of giants can drag the broader market lower even when the rest of the tape is steadier. It also raises the bar for upcoming earnings, where management teams will be pressed on capital spending, AI monetization and margin discipline.

The pressure comes as several megacaps already flag volatility in sales, margins and valuations in recent SEC filings, while peers keep spending heavily on AI infrastructure. If yields stay elevated and earnings fail to justify the buildout, the sector could remain vulnerable to further multiple compression, even if long-term growth stories stay intact.
