Just a guess but it looks like Bank of Nova Scotia is bailing and bottom feeders are picking up the garbage. If it were someone like Leggett and Platt taking a position for a takeover they would have to disclose, which they abviously havent done.
Guess you're right just seems like a lot of shares...13D is required to be filed within 10 days from acquiring 5%. That's around 1 million shares.....FMXI has traded over 4 million over the past 3 days when the price went below 50. At that rate you could acquire over 50% by the time the 13D filing is required.
Texas .. if you are a broker you should know that each share changing hands counts as 2 (1 for the sell, 1 for the buy) unless it is a NYSE transaction, thus the true VOLUME is half of what you may think.
