This thing really is a crime. Bernanke has been shorting billions of shares to short up the Fed's balance sheet.
the only thing is last year it was on this kind of decline down to 19 then BOOM it hit 60. I don't think Benny will allow it this time but you never know.
Sad thing is I have a friend who got totally wiped out naked shorting calls when it was in the 30s last year- if he had been able to hold he'd be a millionaire. It's easy to get greedy on this crap when it drops like this.
Yes you can not short this and go on vacation. I personally am holding a core short and use 10-20k shares intraday. I wait for a pop, wait for the pull back. Then short. My loss on the upside is limited to the high of the last pop. Theoretically I can lose bits all day long. It is rare. More likely you get what has happened over last three days. Thats the norm.
I was idiotic enough to trade this strategy with Apple as it rose. After 25% $100 rise, I was down about 5%. Still got raped but if it would have turned for me (like this is) it is a nice profitable strategy that is remedial.
