I always view money management schemes with a lot of skepticism. Rigid rules about bet sizing seem artificial and without much reasoning behind then while they are always based on assumptions that cannot be verified. An example of this is the ROI estimate based in averages of historical data. Many horse bettors believe that if they managed to win some amount, let’s say $200 after making 500 two dollar bets resulting to a total action of $1,000 they are experiencing an ‘edge’ of 20% or a ROI of 1.20. Of course a closer look into this concept will convince us that this is not the case as this edge is not equally distributed among all bets and it can very well be just a small subset of them where the edge was developed while all the other can represent a losing proposition.
One obvious disadvantage of money management schemes is that any bet we can place in a mutual game is always restricted by the size the pool. This means that your money management system can very well be suggesting a bet sizing that simply cannot be made without decreasing its overlay potential. Of course someone make a case that in this is a situation where we just select what we believe it could be the maximum bet amount without affecting the magnitude of our overlay.. The point I am trying to make though, is that there exist factors that can invalidate the accuracy of money management and this is just one of them.
I believe that the risk we can accept when betting horses is inversely proportional to the size of the bankroll. If our bankroll is just $500, going broke will not have a big impact since the amount is so small that we will be able to easily replace it and start betting again, so making a couple of $250 bets on our best opinions of the day presents a very good risk / reward ratio as we give ourselves the option to multiply the bankroll by a factor or let’s say ten times while, again the risk in not that bad. The same logic does not apply when we are betting out of a $50K bankroll. In this case we have to be very careful about how to manipulate our bet sizing since if we get broke it will take us much longer time and effort to replace our loses.
I think that the best approach to the game is to try to always give to ourselves the best possibility to get lucky by been aggressive both in our picks and in our bet sizing always shooting for the big life changing score rather than frequent small grinds.. If the later is what you try to accomplish, you might be better of if you find a 9 – 5 job…
