Quote from Crispy:
Sounds like playing the float between savings and checkings account to me.
Any opportunity we take we try to incorporate as much leverage as we can without going too far. In some cases this means borrowing to increase leverage, even on a credit card or other personal debt instruments. (Don't think I endorse this but apparently whenever you can move money intraday to make more money just to put the money back so it settles and you don't lose interest is gravy).
