UPS for example. A couple days ago. That was pretty volatile. Or GYI or GM etc.. Those are the ones I'd trade.

using a market short in GYI on 30k shares would not be advisable.
Piece it out and let the mooks nx a 1k shares at a time believing their going to create the 3 cent bounce they want or use the ecn's, hide your size, and collect the rebate.
