Major U.S. stock indexes posted gains Monday as technology stocks rebounded ahead of a critical week for corporate earnings reports. The S&P 500 and Nasdaq Composite both advanced, with investors positioning for quarterly results from major tech companies. Market sentiment improved despite ongoing economic uncertainty.

Trading volume remained elevated as traders reacted to fresh economic data releases. The technology sector led the rally, recovering from recent volatility that had pressured growth stocks. Energy and financial sectors also contributed to the broad-based advance.

Wall Street analysts noted the rebound reflected cautious optimism about corporate earnings strength. Investors are particularly focused on technology giants' quarterly reports, which could set the tone for broader market direction. The advance came as traders balanced earnings expectations against inflationary pressures and Federal Reserve policy signals.
