I confess to remaining shell-shocked from yesterday, so I'm trading more conservatively (e.g. no index options, no futures).
My principal portfolio is now perfectly balanced – 75 small long positions, and 75 small short positions. If the market explodes one way or the other, the hope is that one side's percentage gains would outweigh the other's percentage losses (these aren't random stocks, obviously; they are carefully chosen for their supposed bearish and bullish patterns, so hopefully the odds are in my favor).
As always, you can peruse the watch lists on the right column to see precisely what I own.
