What Moves Stock Prices?

Stock prices change constantly during trading hours. These movements are driven by the interaction of supply and demand — but what drives supply and demand?

Company Earnings

When a company reports strong profits, demand for its stock often increases, pushing the price up. Disappointing earnings have the opposite effect. Quarterly earnings reports are among the most watched events in stock markets.

Economic Data

Reports on employment, inflation, GDP growth, and consumer spending influence how investors feel about the economy — and by extension, about stocks.

News and Events

Product launches, leadership changes, lawsuits, regulatory decisions, and geopolitical events can all move stock prices. The impact depends on how the news changes expectations about future profits.

Interest Rates

When central banks raise interest rates, borrowing becomes more expensive and bonds become more attractive relative to stocks. This can pull money away from the stock market.

Investor Sentiment

Markets are driven partly by psychology. Fear can trigger selling; optimism can drive buying — sometimes beyond what fundamentals justify. This is why prices sometimes appear irrational in the short term.
