Efficient Market Hypothesis. One advantage of the efficient market hypothesis is that it explains how the market sets the value of different stocks. {\displaystyle t} The efficient market hypothesis is a theory first proposed in the 1960s by economist Eugene Fama. An investor wouldn’t be able to analyze the company and determine that the shares should be worth $30, potentially earning a higher return than other investors because they identified an underpriced stock. If information didn’t travel quickly enough for all investors to know it, those with advanced knowledge could buy or sell shares for something other than their fair value. For example, housing markets are less close to the model of efficient market hypothesis because there are significant time lags in buying selling and stamp duty e.t.c. Investors typically do not like to hold stocks during a financial crisis, and thus investors may sell stocks until the price drops enough so that the expected return compensates for this risk.
