After selling his company to Yahoo for $5.9 billion in Yahoo stock, Mark Cuban personally architected a hedge of his enormous wealth with synthetic indexes, taking a $20 million cut for six months of protection before he could hedge the actual Yahoo shares. Compare this to John Z. Rigos, who sold his dotcom for $42 million and walked away with $8 million of stock. Between the day of the sale until the day when he could legally sell his shares, the stock tanked, and Mr. Rigos was left with virtually nothing. Mr. Cuban came from a poor Jewish family; Mr. Rigos from a poor Greek family. Same story, two outcomes... Today Mr. Cuban's net worth is more than $2 billion. I'd say he knows more than "little to nothing" about the market.
