I'm sure some know the deal but can't buy because they are restriced by law from doing so...and some may know and are buying (quietly)..
Most here though, don't know what the outcome will be. Pretty good idea there is a settlement to all classes but in what form and amounts? No clue.
I would advise from setting a sell order if you believe that we win in the end as your order will be the first taken out and those without such orders will receive a larger payday if settlement comes in over the top. inmho.
