Well, I mentioned in a previous post that I was NOT using margin so I had no issues. I did have a stop - I was stopped out - but then I purchased back the same dollar amount of stock (just more shares - THANK YOU!).
I have also had those TDA calls - trying to "advise me" to which I always ask "What was your return last year compared to mine?" and that ends the conversation.
From experience though, back when CITI was going into BK they released a PR at like 6:45PM...price went down...TDA changed margin rules right then...TDA called me and went to voice mail...TDA closed 75% of my position...by 8PM the price had fully recovered.
