Sports, Stocks, & The Magic Quadrants

Picking stocks is a tricky game and so is sports betting. With the NFL and NCAA football seasons only a few months away, we can analyze the professional sports-betting industry to better understand the complexities behind making money in the stock market.

Anybody who has traveled to Las Vegas, and bet on a sporting event, understands that simply choosing a game winner is not enough for a casino to pay you winnings. You also need to forecast how many points you think a certain team will win or lose by (i.e., the so-called “spread”). In the world of stocks, winning/losing is not measured by spreads but rather equities are measured by valuation (e.g., Price/Earnings or P/E ratios).

To make my point, here is a sports betting example from some years back:

Florida Gators vs. Charleston Southern Buccaneers: Without knowing a lot about the powerhouse Southern Buccaneers squad from South Carolina, 99% of respondents polled before the game are likely to unanimously select the winner as Florida – a consistently dominant, nationally ranked powerhouse program.

The tougher question becomes trickier if football observers are asked, “Will the Florida Gators win by more than 63 points?”(see picture below). Needless to say, although the Buccs kept it close in the first half, and only trailed by 42-3 at halftime, the Gators still managed to squeak by with a 62-3 victory. Importantly, if you had bet on this game and placed money on the Florida Gators, the overwhelming pre-game favorite, the 59 point margin of victory would have resulted in a losing wager. In order for Gator fans to win money, they would have needed Florida to win by 64 points.

If investing and sports betting were easy, everybody would do it. The reason sports betting is so challenging is due to very intelligent statisticians and odds-makers that create very accurate point spreads. In the investing world, a broad swath of traders, market makers, speculators, investment bankers, and institutional/individual investors set equally efficient valuations over the long-term.

The goal in investing is very similar to sports betting. Successful professionals in both industries are able to consistently identify inefficiencies and then exploit them. Inefficiencies occur for a bettor when point spreads are too high or low, while investors identify inefficient prices in the marketplace by shorting expensive stocks and buying cheap stocks (i.e., undervalued or overvalued).

To illustrate my point, let’s take a look at Sidoxia’s “Magic Quadrant“:
