What Is a Bear Market?

A bear market is when a market experiences prolonged price declines. It typically describes a condition in which securities prices fall 20% or more from recent highs amid widespread pessimism and negative investor sentiment.熊市是指市场经历了长期的价格下跌。它通常描述的情况是，由于投资者普遍悲观和消极情绪，证券价格从近期高点下跌20%或更多。

Bear markets are often associated with declines in an overall market or index like the S&P 500, but individual securities or commodities can also be considered to be in a bear market if they experience a decline of 20% or more over a sustained period of time—typically two months or more. Bear markets also may accompany general economic downturns such as a recession. Bear markets may be contrasted with upward-trending bull markets. 熊市往往与整体市场或指数下降像标准普尔500指数,但个别证券或商品也可以被认为是在熊市中如果他们经历了下降20%或更多的持续一段时间两个月或者更多。熊市也可能伴随着经济衰退等整体衰退。熊市可能与上升趋势的牛市形成对比。
