When I put in the hours, run about $50,000 per month through the sports books. A little more during football season, sometimes take breaks where it is quite a bit less. Only about $1 - $2,000 through the stock broker per month. Sports can get resolved in a few hours, stocks sometimes take a couple decades, so seems a bit silly to compare the two. For people who profit off both, the lower rollers will do a lot more through sports, but because of limits, the higher rollers will do a lot more through stocks
