Wall Street’s major stock indexes, including the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite, show long-term predictability but face volatility in shorter time frames. In early 2025, the S&P 500 reached a record high, while the Dow and S&P dipped into corrections, and the Nasdaq entered a bear market, highlighting significant fluctuations, including the S&P’s notable two-day decline and subsequent historic single-day point gain.
