There are several headlines proclaiming the Zuckerberg lost $16,000,000,000.oo today. No he didn't. His new worth may have declined that much, but he never had $16B in his hands or anywhere else. Hed had stock in his company that lost that much in value. As soom as the market tech stocks recover, he'll gainit back. no big deal.If he had had $16B in a bank that failed and the money was gone from the back, then he lost it.
A stock value drop is only a NET Worth decline.
Somehow I don't feel all that sorry for him. He is still worh multiple billions (approximately 64B if the 16b =20% drop. I think he can survive n that if he cashes it in.
