Amos will name names at 12 noon today. The clue is in Amos' description of the as yet unspecified institution:
“With a 192 year old history and 37,000 employees, its crash would drop like an A-bomb on unsuspecting shareholders…”
BMO was founded in 1817.
PS. This report's been floating around since the 20th and hasn't moved BMO's stock at all. So who knows?
