If you are looking for a rule of thumb, usually it only gets worse. Price goes down after the split and eventually another reverse split is in the cards. If the motivation is to avoid delisting, it's usually a lost cause. Evils shorts will pummel it until it's no longer shortable.
thanks I was looking for a list of reverse splits by date. do you know where such a list is availiable
If there are forthcoming it will show. it only shows listed stocks, many times stocks which do reverse split are on BB and then they reverse split and come back for listings.
