The upper Bollinger Band, also known as the upper boundary or upper envelope, is the line connecting the highest points of a stock's price within a certain time period. This time period can vary based on investors' needs, such as one day, one week, one month, etc. When a stock price touches or breaks through the upper Bollinger Band, it often indicates that the upward trend of the stock price is nearing its end, and investors should be alert to the risk.

Firstly, it can help investors determine whether the upward trend of a stock price is ending, thus avoiding blindly chasing high prices. Secondly, the upper Bollinger Band can be combined with other technical indicators, such as MACD, RSI, etc., to improve the accuracy of analysis. In addition, the upper Bollinger Band can also serve as a basis for investors to formulate stop-loss strategies. When the stock price falls below the upper Bollinger Band, investors can stop losses in time to avoid进一步扩大损失。

Section 3: Limitations of the Upper Bollinger Band

While the upper Bollinger Band has certain application value in stock market technical analysis, it also has its limitations. Firstly, the formation of the upper Bollinger Band is influenced by various factors such as market sentiment and policy changes, making it not entirely reliable.
