A stock chart is a visual representation of a company's stock price over time. It typically displays the stock's price on the vertical axis and time on the horizontal axis. Investors use stock charts to analyze trends, patterns, and price movements, helping them make informed decisions about buying or selling shares. There are different types of stock charts, including line charts, bar charts, and candlestick charts. Each type provides unique insights into the stock's performance. Technical analysis often relies on these charts to identify potential future price movements based on historical data.
