Enrich Your Future 02: How Markets Set Prices

In this episode of Enrich Your Future, Andrew and Larry Swedroe discuss Larry’s new book, Enrich Your Future: The Keys to Successful Investing. In this series, they discuss Chapter 02: How Markets Set Prices.

LEARNING: Invest in passively managed funds and adopt a simple buy, hold, and rebalance strategy. While gamblers make bets, investors let the markets work for them, not against them.

“The only way to beat an efficient market is to either know something the market doesn’t—such as the fact that a team’s best player is injured and will not be able to play—or to be able to interpret information about the teams better than the market (other gamblers collectively) does.”

Larry deeply understands the world of academic research and investing, especially risk. Today, Andrew and Larry discuss Chapter 02: How Markets Set Prices.

Chapter 02: How Markets Set Prices

In this chapter, Larry explains how markets set prices—probably the most important thing investors need to learn before they invest a penny. Without this knowledge, investors won’t know whether the stock they buy is undervalued or overvalued. Larry insists that investors should have a good understanding of how the market gets to a specific price.

Point spread betting

To explain the complicated concept of how markets set prices, Larry uses an analogy related to college basketball backed up by academic research. Duke is a perennial contender for the national championship. Every year, it’s ranked in the top 25. At the start of every season, most college teams that are good try to schedule a few of what are called “cupcake” games to give their players a chance to get in the routine, learn the plays, get to know each other, etc., before they meet tougher competition.

Duke often scheduled a game against Army. Army traveled down every year to Duke, where they would get a big payday, and Duke would have an easy win. No one in their right mind would bet on Army to win that game because they have played probably 30-40 times already, and Duke has won every game. And they could play another 30 or 40 times and win every game. However, people decide to entice others to bet on Army.

To make it an equal bet, they create a point spread. The bookies set the initial point spread where they think they can get an equal amount of money bet on both sides. The bookies do their analysis and set the initial spread, but they don’t set the actual spread, which is determined by the betters in their actions. So if a lot of money starts coming in betting on Duke, the bookies will raise the spread until money starts coming in on Army until they get an equal amount of money. Then, the winner has to put up $110 to win $100. If they win, you get their $110 back and the bookies’s $100. But if you lose, you lose $110, not $100. So the bookies collect that $10 on the total of $200. So, what happens is that the point spread is moving based on the collective wisdom of the markets.

It’s very easy to determine whether Duke is going to win or not. But it’s tough to beat that point spread. Very rarely does the point spread predict the actual outcome. However, it is an
