problem for many is they dont realize only a few brokers have the new shares ready for trade in their accounts
I dont mess with any corporate actions that cause share settlement through the TA
one time I had shares in TDA, was too new and dumb to know the stock was even splitting, then when it split it ran up I was excited because I was up around $10,000...BUT
TDA didnt have the split-adjusted shares in my account for over a week
by the time they did I was -down money :-(
ETRADE was one of the only brokers that fronted customer shares before they were even settled by the TA
