I thought that this one apropros in light of yesterday's and today's market action.
I bought some HLYS today. It might be foolish, but it trades around $6, has cash on the books of $3 and no debt. Sales trends are down, but they are still generating sales. It's purely spec. I also bought some SYNL. Very small position.
I'm still mostly cash. I've no short positions other than 200 shares of SMN in one of my retirement accounts.
