Value investing sounds really cool. It sounds savvy, it sounds smart, it sounds responsible, it sounds like it makes a lot of money. I mean, Warren Buffet is a value investor!

So what is a value investor? Well, a value investor is someone who invests in value companies. So what’s a value company? I’m glad you asked. Essentially, a value company is one whose stock price is about the same (could be a little higher or lower) than its intrinsic, or book, value. A lot of words there but stick with me. The intrinsic value of a company is what you get when you add up all the company’s assets, its land, warehouses, products (which can include patents), equipment, cash, etc. It might seem a little odd that a company’s stock price wouldn’t always be close to its intrinsic value, but the stock market prices of growth companies (the opposite of value companies) can actually trade multiples of 8 times higher than its intrinsic value. This happens because the market expects the growth company to continue growing. Value companies aren’t typically expected to grow much, they’re often characterized as distressed. So value investors are analyzing these value companies and deciding which ones they think are actually undervalued and which ones could bounce back. Again, it sounds great, they’re the brilliant nerdy guys reading all of the fine print and finding the deals in the stock market, the companies that are underpriced. All you have to do is hitch up to their wagon and ride those value companies up when everyone else figures out how valuable they actually are. Sounds pretty responsible, right?

A semi-famous value investor, Michael Burry, featured in the Big Short (as Christian Bale) crushed the growth stock market from 2001-2005. In the middle of 2005, he was up 242% when the U.S. large growth market (S&P500) was down 6.84%. Michael Burry is the quintessential weird genius that we love to fall in love with, and hand our money over to. He did things differently, he didn’t take normal massive fees, he was incredibly awkward with people in person, he kept to himself, he obsessively studied the interworkings of the companies he invested in, just about everything you would expect from the next market genius. He’s most famous for predicting, and attempting to short, the housing crash in 2007. And now’s he’s rich, and semi-famous, and still investing. He recently stated that passive investing is a bubble, that he’s concentrated on water (you get it), that GameStop is undervalued, and that Asia is where it’s at. While these investment tips might accord with the laws of value investing, they hardly seem prudent.

Michael Burry is definitely smarter than I am, but here’s what I know:

1) Ken French, a professor of finance at the Tuck School of Business, Dartmouth College, who has spent much of his adult life researching and publishing in the sphere of economics and investing, conducted a study of mutual-fund managers (Luck versus Skill in the Cross-Section of Mutual Fund Returns) and found that only the top 2% to 3% had enough skill to even cover their own costs. Eugene Fama, another father of economic and investing academia, who co-wrote the paper with Ken French, summarizes their findings this way: “Looking at funds over their entire lifetimes, only 3% demonstrate skill after accounting for their fees, and that’s what you would expect purely based on chance.” Of the managers who do exhibit enough skill to cover their own costs, it’s hard to determine whether an actual skill is at work or it’s simply a facet of luck; most free-market scholars lean towards luck.

2) Fama continues: “Even the active funds that have generated extraordinary returns are unlikely to do better than a low-cost passive fund in the future.” Some managers do well enough to cover their own costs and beat the market in a given year. Unfortunately, their success languishes quickly and they regress to the same plane that active managers on the whole occupy, which is underperforming the market.

So is Michael Burry, or any value investor, the weird, brilliant savant that we desperately want to attach our life-savings to, or is he one of the 3% of managers who have done well enough to cover their own fees, but who the data says is more likely to regress to market underperformance mean than to do it again? I know which side I’m playing.
