The Efficient Market Hypothesis is a theory that states that the global markets are always 100% efficient, i.e. that all prices are 100% accurate and that there is never any inefficiency. This means that, in theory, it should be impossible to outperform the market, although this has been clearly shown to be untrue (in a select few cases at least).
多年来,一些投资者(例如沃伦·自助力)始终击败了市场,这在某种程度上反驳了有效的市场假设。
