Yesterday there was a thread about hedging a parlay, as there is at least 5 times a week every week. I am constantly amazed at just how many people assume that hedging is a good practice. At least 90% of the people here – when asked – give the advice to hedge the last game of a parlay.
For those interested, here is the math, and the reason that it is dumb to hedge.
The first situation is what the poster yesterday did, as he parlayed teams on 2 different days. His first 3 teams were on Sunday, and his 4th team was on Monday. This is a big no no. He would be much better off betting a 3 team parlay on Sunday, and then rolling all of the proceeds in to a straight bet on Monday:
Option 1: Bet a 4 team parlay at 10-1. Bet 100, win 1,000.
Option 2: Bet a 3 team parlay at 6-1, bet all proceeds straight up on Monday team. Bet 100, win 1,336.
Option 2 makes you MUCH more money (1,336 vs 1,000) on your 100 dollar bet. This is a no brainer.
The second situation is the one always talked about here and is the one that is most misunderstood. If you have already put a team in a parlay, and nothing has fundamentally changed with the line or game situation, you have to pay a tax to hedge (vig). So if you know you are going to hedge, don’t bet the last team in that parlay to begin with. Here is the math:
Option 1: Bet a 4 team parlay and hedge the last game.
You bet 100 to win 1,000 on a 4 team parlay, the first 3 win, and you decide to hedge the last game. The last game is
Option 2: Bet a 4 team parlay and don’t hedge the last game, and ride it out.
You bet 100 to win 1,000 on a 4 team parlay, win the first 3 games, and let it ride out. If the last game has a 50/50 expectation, you will win it half the time and lose it half the time. So your expected value on letting it ride is 500.
Option 3: Realizing you are going to hedge the last game of your 4 team parlay, you just bet a 3 team parlay instead.
You bet 100 to win 600 on a 3 team parlay because you know you like to hedge. You win your first 3 games and win 600.
