Stock's Previous Day's Close: Definition and Importance

The stock's previous day's close, as the name suggests, refers to the closing price of a stock on the previous trading day. This is a crucial data point in stock trading, carrying multiple meanings for investors.

Firstly, the previous day's close reflects the overall market sentiment and trend of the previous day. If the stock's previous day's close price increases, it usually means that the market has a positive view of the company or industry, and investor sentiment is high. Conversely, if the previous day's close price decreases, it may indicate market concerns about the stock's prospects, and investor sentiment is relatively pessimistic.

Secondly, the previous day's close is an essential benchmark for calculating stock price fluctuations. The fluctuation range is a metric that measures the magnitude of stock price movements, and it is calculated based on the previous day's close price. Therefore, the accuracy of the previous day's close price is crucial for assessing the stock's performance on that day.

In addition, the previous day's close is also an important reference for many technical indicators and strategies. For example, some investors refer to historical previous day's close prices to formulate trading strategies, such as moving averages, relative strength indexes, etc. These indicators are calculated and analyzed based on historical price data, so the accuracy of the previous day's close price is crucial to the effectiveness of these indicators.

Overall, the stock's previous day's close is a crucial data point in stock trading. It is not only a reflection of market sentiment but also a benchmark for calculating price fluctuations and technical indicators. For investors, it is necessary to understand and pay attention to the stock's previous day's close.
