The stock market index is a crucial tool reflecting the overall trend of the stock market. In simple terms, it is a weighted average price of a group of stocks, representing the performance of the entire market. This index typically includes numerous representative company stocks on the market, and through specific calculation methods, the price movements of these stocks are combined to form a single numerical value.

The primary function of the stock market index is to provide investors with a macro and comprehensive perspective for market observation. Through the rise and fall of the index, investors can quickly grasp the overall trend of the market, judge changes in market sentiment, and thus make more informed investment decisions. Meanwhile, the stock market index is also one of the key indicators for evaluating the economic development status of a country or region.

In addition, the stock market index is often used to measure the performance of investment portfolios. Investors can assess whether their investment strategies are aligned with the overall market trend by comparing the performance of their portfolios with the corresponding index, and then adjust their portfolios to achieve better investment returns.

均线扣抵技术是一种在股市分析中常用的技术分析方法。其核心理念是通过计算股价与不同周期移动平均线的距离，来判断股价的走势和可能的转折点。当股价接近或触碰某条移动平均线时，该技术认为股价可能会受到该平均线的支撑或压力，从而发生反转或持续走势。

具体来说，均线扣抵技术包括了对股价与短期、中期和长期移动平均线之间关系的分析。当股价从下方穿越某条移动平均线时，这通常被视为买入信号；而当股价从上方穿越该平均线时，则可能被视为卖出信号。此外，该技术还关注股价与移动平均线之间的乖离率，即股价与平均线的偏离程度，以此来预测股价的未来走势。

均线扣抵技术虽然在股市分析中具有一定的参考价值，但投资者仍需结合其他分析工具和市场信息，进行综合判断，以做出明智的投资决策。

The Moving Average Convergence Divergence (MACD) technique is a commonly used technical analysis method in stock market analysis. Its core concept is to judge the trend and potential turning points of stock prices by calculating the distance between the stock price and different period moving averages. When the stock price approaches or touches a certain moving average, this technique believes that the stock price may be supported or pressed by that average, leading to a reversal or continuation of the trend.

Specifically, the MACD technique involves the analysis of the relationship between the stock price and short-term, medium-term, and long-term moving averages. When the stock price crosses a moving average from below, it is usually considered a buy signal; when the stock price crosses the average from above, it may be regarded as a sell signal. Additionally, this technique also focuses on the divergence rate between the stock price and the moving average, which measures the deviation of the stock price from the average, to predict the future trend of the stock price.

While the MACD technique provides valuable reference in stock market analysis, investors still need to combine other analysis tools and market information for comprehensive judgment to make informed investment decisions.
