同学你好,这里提到的是momentum,过去上涨的股票已之后还会继续章,过去下跌的股票之后还会继续跌,那么就要看下原版书中是如何描述momentum的,看看它涉及到哪些behavioral biases。The availability bias in this context is also called the recency effect, which is the tendency to recall recent events more vividly and give them undue weight. Regret is the feeling that an opportunity has been missed, and is typically an expression of hindsight bias.
Availability bias和hindsight都有提及,availability是回想起最近的市场行为,比如某些股票最近一直上涨,那么人们想到这件事就更有可能去买入该股票,导致买方力量强,使得它继续上涨,促成了momentum。Regret是hindsight的体现,比如一只股票过去上涨,你会想,我早就知道它会涨可惜我没有买,从而会导致后悔,这种情绪会促使你买入上涨股票,进一步导致momentum。
