股票必杀线是什么意思？

中文段落：

股票必杀线，又称为死亡线或死亡交叉，是技术分析中的一种重要概念，主要出现在股票、期货等金融市场的价格图表中。当某一技术指标（如移动平均线）从上方向下穿越另一技术指标（如另一条移动平均线）时，形成了一种被认为是卖出信号的特殊交叉形态，这就是所谓的“股票必杀线”。

具体来说，股票必杀线通常指的是短期移动平均线（如5日、10日均线）从上方穿越长期移动平均线（如60日、120日均线）的交叉点。这一交叉点被视为一个重要的参考点，因为它可能意味着市场趋势的转变，从上涨趋势转变为下跌趋势。因此，许多投资者和交易者都会密切关注这一信号，并在必要时采取相应的交易策略。

然而，值得注意的是，股票必杀线并非万能的预测工具。虽然它提供了一个卖出信号的参考点，但并不能保证每次出现必杀线后股价一定会下跌。市场的走势受到多种因素的影响，包括宏观经济环境、政策变化、公司业绩等。因此，投资者和交易者在使用股票必杀线时，应结合其他技术指标和市场信息进行综合分析，以做出更准确的决策。

英文段落：

The stock "killer line," also known as the death line or death cross, is an important concept in technical analysis, primarily appearing in price charts of stock, futures, and other financial markets. When a technical indicator (such as a moving average) crosses over another technical indicator (such as another moving average) from above, it forms a special crossing pattern considered a sell signal, known as the "stock killer line."

Specifically, the stock killer line typically refers to the crossing point where a short-term moving average (such as a 5-day or 10-day moving average) crosses over a long-term moving average (such as a 60-day or 120-day moving average) from above. This crossing point is regarded as an important reference point because it may indicate a change in market trend, from an uptrend to a downtrend. Therefore, many investors and traders closely monitor this signal and adopt corresponding trading strategies when necessary.

However, it's worth noting that the stock killer line is not a universal prediction tool. While it provides a reference point for a sell signal, it cannot guarantee that the stock price will decline every time the killer line appears. Market movements are influenced by various factors, including the macroeconomic environment, policy changes, and company performance. Therefore, when using the stock killer line, investors and traders should combine it with other technical indicators and market information for comprehensive analysis to make more accurate decisions.
