I smell bullshit. First of all a significant number of small to midsized momentum funds are headquartered in Florida. They have performed very well and if I would entrust my money to anyone then those guys. Secondly if your story about the exotic derivative was remotely true then the client would have easily sued the wealth management unit, especially when a trade goes sour by such amount within days. Sorry but fun story but that's all to it I feel....
A trader who has been an exchange member for a couple of decades and traded on both the floor and the screen said he refuses to do business with any brokers or money people in Florida because of the general lack of honesty there.
I've heard of a clearing firm reverse-engineering a customer's trading strategy and share it with their favored clients resulting in the trade drying up for the original customer.
And also a broker using its discretion to jack up margins overnight on a thin product, then liquidate customer positions against orders rested well off market by the brokers' affiliated proprietary trading/market making unit.
A top feeder wanted a quote in substantial size for an exotic option on a very illiquid currency...the bank didn't want the risk on its books but wanted the order...so they had their wealth management unit convince a billionaire's son that the opposite side was a good "investment" - the latter was forced out of his position in a matter of days with an 8 figure loss.
