Markets face a broad-based selloff as major U.S. stock indices decline sharply. The Nasdaq Composite tumbled over 2% during intraday trading, while the S&P 500 retreated 1.43% and the Dow Jones Industrial Average fell 0.95%, according to market data. This broad decline across all three major indices reflects a shift toward risk-off positioning among investors. The widespread market weakness signals growing caution about the economic outlook, with traders moving defensively in response to current conditions. Such synchronized declines across different market segments underscore the broad nature of the current market downturn and heightened uncertainty among market participants.
