Not really a sign of anything. My broker called me once to ask if I really placed a stock order. Said they were just making sure because of recent(at the time) hackers into peoples accounts at other brokers.
I thanked him for being vigilant but told him to make a note on the file not to call unless the trade is for more than $300 on a penny stock. Damnit, look at the account, there is nothing but penny stocks in there, 100s of them.....
