How does stock price go up and down

What causes stock prices to fluctuate even within a single trading session?

Stock prices go up when demand from buyers exceeds the supply from sellers, and go down when the opposite occurs. This balance is influenced by a variety of factors, including company news, earnings reports, economic data, and overall investor sentiment. Prices can also be affected by broader market trends, geopolitical events, and changes in interest rates. The constant interaction of buyers and sellers, each with their own expectations and strategies, causes prices to fluctuate throughout the trading day.,
