He believes “buy and hold is a crock of $%#!” and diversification is for idiots. Cuban also addresses how patent law stifles creativity, but refuses to address the NBA lockout.

” refuses to address the NBA lockout.”
Can you blame him? Are his fines up to $5MM yet?
He wrote up most of this on his blog.
And TrickStyle, yes, I’ll give you odds he’s not diversified in the Markowitzian sense of the phrase. Why be exposed to areas you don’t understand just because they might appreciate–or might be a NZ or Chinese ponzi scheme?

Cuban is a bright guy, but his advise that investors should not diversify is terrible.
It’s irresponsible for Cuban to suggest that average investors stay in cash and avoid diversifying.
