parking cash.....
i'm sitting on a barrow load, and it usually ends up in the basic account attached to my broking account...however, i do dabble with hybrids, using that cash. A favorite was AQHHA before they redeemed, the latest was WBCPH. I buy for the quarterly income, but will happily trade any reasonable price swings( particularly after the "ex" period) to scab a little extra income.....otherwise, it can sit there, with no stress as i can make a decent trade to cover any opportunity loss. My only concern is for extended bouts of "sitting", which is when i can end up forcing trades or buying too early, which has a higher cost than cash
