According to the efficient markets hypothesis, does the price of a stock take into account the company's growth prospects? It says that it is hard to find undervalued stocks but theoretically, is it still possible to get above market returns if the growth is realized? For example, if I invested in Apple 20 years ago, the price may have been fair then but I would still have gotten above average returns from the company's growth. I just want to know what that theory says about this, not whether the theory is correct or not. Thanks
