"Sports betting is a matter of odds, while investing is something more based considering we have done our home work and we understand how the market works." That's really a distinction without much of a difference. If you watch the folks at Tasty Trade (and I encourage you to do so) they look at investing in the market almost exclusively as a matter of odds. They believe in the power of large numbers and make 'bets' on the market no different than people do on the Mavericks. The general principles that work in markets will work in sports - hedging, middling, scalping ect. But, because of the electricity, immediacy and binary nature of sports betting, it's much more difficult for gamblers to manage their money. In short, the markets do behave similarly enough that you should expect similar returns. The problem it turns out, as is the case with bad drivers, is the nut behind the wheel.
