One firm’s senior wealth management executive said it was seeing people with $30 million in their brokerage account being completely wiped out within days. Weekly margin call lists have started swelling, this executive added.
Wall Street bankers have been particularly hard hit. Many were given large amounts of their company’s stock in annual bonuses, only to see it disappear. Making matters worse, the wealth management executive said, many of those bankers borrowed against those shares to buy stocks of other financial companies that they thought might rebound more quickly. Those shares have since plummeted."
I'm trying to imagine some guy worth $15 million explaining to his wife why he had to leverage all of it because that wasn't enough. And then lost it all and maybe more. Big OUCH.
