This final note today, in which the somewhat arcane art of stock picking jumps the shark. A blogger at the Huffington Post noticed something unusual the other day: When actress Anne Hathaway is in the news, shares of Warren Buffett's company Berkshire Hathaway go up.

His theory is that computer trading programs pick up Internet chatter about Hathaway the actress, apply it to Hathaway the stock, and spit out orders to buy.

Me? I'm more of a Gwyneth Paltrow guy myself, but there's probably no way to profit from that.
