Opening Price: The price at which a stock initially trades on an exchange on a trading day is known as the opening price. The market hours for shares are 9:15 AM to 3:30 PM. However, the pre-market window, which runs from 9:00 AM to 9:08 AM, is when the exchange begins accepting orders. They gather the orders during this period, and seven minutes before the markets open, they match these orders to determine the price at which the stock will begin trading for the day at 9:15 AM.

The opening price is determined during a pre-market window, and depending on the supply and demand for a stock, it may be different from the closing price from the previous day. The price of a specific stock may change between the hours between the closing price and the beginning price of the next trading day due to a variety of variables, including:

• After market orders (AMO): AMO indicates that orders are being made even after the markets have closed, which causes the prices of stocks to change. As a result, AMO has a significant impact on the stock price between the closing and opening price.
• Earnings reports: A company's earnings report can influence the stock price before the market opens.
• Economic data: Economic data, such as employment figures or inflation data, can also influence the opening price.
• Market sentiment: Market sentiment, or investor confidence, can also impact the opening price. If investors are bullish, the opening price may be higher than the closing price. If they're bearish, it may be lower.
