为什么做空？

做空是一种投资策略，通常指在金融市场预测某种资产（如股票、外汇或商品等）的价格将下跌时，投资者通过借入该资产并立即卖出，希望在价格下跌后以更低的价格买回该资产并归还借入资金，从而获得盈利。以下是几个关于为什么做空的原因：

1. 价格下跌获利：当投资者预测某种资产的价格将下跌时，通过做空可以获得盈利的机会。如果资产价格下跌，做空者将能够以低于借入价格的价格买回该资产，从而归还借入资金并获得盈利。英文翻译为Why short?

Shorting is an investment strategy that typically involves borrowing a financial asset, selling it immediately, and hoping to buy it back later at a lower price and return it to the lender to generate a profit. Here are several reasons why shorting is done:

1. profiting from price declines: When investors predict a price decline for a certain asset, shorting provides an opportunity to profit from the decline. If the asset price falls, short sellers will be able to buy back the asset at a price lower than the price at which they borrowed it, repay the loan and generate a profit.
