空单回补是什么意思？

中文版：

空单回补，又称为空头回补或空头平仓，是金融市场中的一个重要概念。它指的是当投资者预测某个股票或资产的价格会下跌时，会先卖出该股票或资产，形成空头仓位。但随后，如果市场走势与预期相反，即股票或资产价格上涨，为了避免进一步的亏损或抓住价格上涨的机会，这些空头投资者会选择买回之前卖出的股票或资产，以关闭空头仓位。这个过程就称为“空单回补”。

空单回补行为通常会对市场产生积极的影响。当空头投资者开始回补仓位时，他们会在市场上买入股票或资产，从而增加市场的买盘力量。这有助于推高股票或资产的价格，并可能引发一轮上涨行情。因此，空单回补往往被视为市场上涨的积极信号之一。

此外，空单回补也反映了投资者的情绪变化。当空头投资者开始回补仓位时，这可能意味着他们对市场的看法正在发生变化，从悲观转向乐观。这种情绪的转变可能会进一步推动市场的上涨。

What Does Short Covering Mean?

Short covering, also known as short closing or buying to cover, is an important concept in financial markets. It refers to the process where investors, having initially sold a stock or asset anticipating a price decline, decide to buy back the same stock or asset to close out their short position. This typically occurs when the market moves against their expectations, i.e., when the price of the stock or asset rises. To avoid further losses or capitalize on the price increase, these short sellers choose to repurchase the previously sold securities, thereby closing their short position. This process is referred to as "short covering."

Short covering usually has a positive impact on the market. When short sellers start covering their positions, they add buying pressure to the market by purchasing stocks or assets. This buying activity can push up the price of the stock or asset and potentially trigger an uptrend. Therefore, short covering is often viewed as a positive signal for market rallies.

Additionally, short covering reflects changes in investor sentiment. When short sellers start covering their positions, it could mean that their perception of the market is shifting from bearish to bullish. This shift in sentiment can further fuel the market's upward momentum.
