For a rule of thumb my money management strategy has not changed over my professional handicapping career. I wager 1-5.5% of my bank roll. 5.5% on my most confident plays and 1% on my least confident plays and it has produced huge results, especially in college football.
The purpose of this article is to compare betting on sports with the stock market against good growth stock mutual funds with long term yearly ROI's of around 10-12% according to the market average. You can expect 12% yearly growth in the stock market if you know what you are doing. Actually it's not that hard as long as you stick to simple plan and don't get too greedy. Here is a great article on the 12% reality, "The current average annual return from 1926, the year of the S&P's inception, through 2011 is 11.69%. That's a long look back, and most people aren't interested in what happened in the market 80 years ago." For example purposes we looked back at the last 10 years to compare with my college football picks since the start of my career.
