We invest at this end of the market precisely because it is disfunctional. You wouldn't get the significant under and overvaluation if the market was efficient. Buy at one and sell at the other and you can make very large gains. But it is extremely difficult to do so and requires a lot of patience, which most investors do not have.
Of course, it can also not pan out the way you plan, which is why you need to invest more broadly than one share.
