When we talk about value investing there is a lot of evidence that value investors have been on the right side of the trade. The statistical studies that run against or contradict market efficiency almost all of them show that cheap portfolios—low market-to-book, low price-to-book—outperform the markets by significant amounts in all periods in all countries—that is a statistical, historical basis for believing that this is one of the approaches where people are predominantly on the right side of the trade. And, of course, someone else has to be on the wrong side of the trade.
Those studies were first done in the early 1930s; they were done again in the early 1950s. And the ones done in the 1990s got all the attention because the academics caught on. There is statistical evidence that the value approaches—buy cheap securities—have historically outperformed the market. Buying Cheap works.
