大众引导大众最近股市下跌得非常厉害。尤其每闻管理层出利好时,第二天,股市多半会以暴跌方式回应。这种非理性下跌,正好说明了一个道理:在一个参与者众多的市场中,个人理性行为往往会导致集体行动的非理性。 The public led the public The recent stock market fell very powerful. In particular, when management of every news business goes well, the next day, the stock market will probably respond with a plunge. This irrational decline shows exactly the truth that in a market with a large number of participants, individual rational behavior often leads to irrationality in collective actions.
