场外大量抛售

这里的场指的是交易所，场内及交易所内（比如在国内，指的即是上海证券交易所和深圳证券交易所），场外即交易所以外。场外交易一般用Over-the-counter (OTC) or off-exchange trading来表示。

但由于场外大量抛售一般是通过二级市场减持来完成的。因而这一术语的英文一般由此翻译为secondary offering.

The term secondary offering refers to the sale of shares owned by an investor to the general public on the secondary market. These are shares that were already sold by the company in an initial public offering (IPO).

空头回补

空头回补是指空头在高位卖出开仓，并且价格下跌到一定的程度时因为多头反扑被迫平仓甚至反手做多，此时造成价格暂时反弹上涨，但不能反弹到原来的高度，相当于空头获利出局。

在期货中，指外汇市场上原本做空的投资者(看跌先卖出)在交易方向和持有的头寸反向发展时被迫平仓或反手做多(买入)的行为.由于原来投资者是做空,签下期货合同时的方向是卖出,平仓时就需要将其买入.这样一来,原来的空头变成了多头,对价格上涨起了推波助澜的作用.如果某一品种的期货数量比较小,一方的资金又充足,就有可能不断拉高(或压低)价格,迫使对手强制平仓,使价格继续朝着对自己有利的方向发展.

空头回补的英文为为short covering，下文为其英文释义：

Short covering refers to buying back borrowed securities in order to close out an open short position at a profit or loss. It requires purchasing the same security that was initially sold short, and handing back the shares initially borrowed for the short sale. This type of transaction is referred to as buy to cover.

以下为相关双语示例，供参考：

空头回补大多出现在市场持续下跌之后，没有太多上行动力之时。

Many times, short covering will occur after a market has been in a sustained downtrend without much upside movement recently.
