Excellent, SUSA will open up on the Grey Sheets on March 15 at a much lower PPS and then you can pick when to close out your very lucky short position.
Typically, when suspended stocks reopen on the Greys, they lose 60% to 80% of their value on the first trading day. After that, there may be a dead cat bounce.
Volume usually declines rapidly, though, so you'd probably do best to cover while there's still some liquidity.
