There's that old (apocryphal, I think) chestnut about someone asking JP Morgan what he thought the market would do in the future, and him answering, "It will fluctuate." Back when I was working at a trading firm, it became particularly apparent to me that both bad days and good days were a dime a dozen.

Whether or not that's newsworthy depends, I suppose. In the USA, mass murders seem to be more common than major market corrections, but I wouldn't want to say that they're not newsworthy simply because they happen a lot.
