US equity markets closed lower on Monday, with the Nasdaq Composite and S&P 500 retreating as selling pressure in large-cap technology stocks overwhelmed broader market resilience.
The decline was driven by losses among megacap names, which offset positive developments in the semiconductor sector.
The Dow Jones Industrial Average managed to post a modest gain, rising 87.33 points, or 0.17%, to close at 51,936.23.
This divergence highlights the concentration of selling pressure within the technology-heavy indices, while broader industrial and value-oriented components of the market held firm.
The session underscores the ongoing volatility in the tech sector, where investor sentiment remains sensitive to valuation concerns and rotation out of high-growth names.
Despite upbeat outlooks from chipmakers, the weight of megacap declines proved sufficient to drag the broader market lower.
