Key market indicators turned sharply negative on Tuesday as software stocks slumped, deepening their losses since the start of the year. The tech-heavy Nasdaq dropped 1.4%, weighed down by sinking tech stocks, while the S&P 500 and Dow Jones Industrial Average also closed lower. The sell-off lacked a clear trigger, but appeared to be an acceleration of the moves that have characterized markets so far in 2026, with software stocks hit particularly hard amid concerns about the rise of AI and 'vibe coding' disrupting the industry.

Why it matters

The consensus on Wall Street is that 2026 will be a solid, if unremarkable, year for the stock market, but analysts warn investors should expect bouts of volatility amid an uncertain geopolitical and economic landscape. This latest sell-off highlights the jitters and uncertainty that have characterized markets so far this year, with software stocks bearing the brunt of concerns about the impact of emerging technologies like AI.

The details

The sell-off was led by software stocks, which have been hammered this year by concerns about AI disruption. The release of workplace productivity tools from AI startup Anthropic on Tuesday amplified those fears, sending shares of companies like Intuit and Salesforce sharply lower. The tech giants that have been treading water so far this year, such as Nvidia and Broadcom, also slipped, while red-hot memory and data storage stocks like Western Digital and Sandisk continued to surge.

• The major indexes came into Tuesday's session riding high, with the S&P 500 closing a fraction of a percentage point off a record high on Monday.
• The S&P and Nasdaq were both down on the day within a half hour of the open on Tuesday.
