P112 Overreaction effect.. overreaction的定义不是"Overreaction is an emotional response to new information. In finance and investing, it is an emotional response to a security like a stock or other investment, which is led either by greed or fear. Investors, overreacting to news, cause the security to become either overbought or oversold, until it returns to its intrinsic value."吗?感觉和ppt上说的垃圾股过几年反而表现更好不是一样的情况

同学你好,
讲义上的描述是过度反应的一个例子。指在过去三年或五年内股票回报率低的公司(亏损公司)比在过去一段时间内股票回报率高的公司有更好的后续回报。
由于投资者非理性的过度反应,导致超买或超卖的现象,使股票的价格或高或低得偏离其内在价值。
