Yes, I think you're right on your source. In short, markets move around for a whole host of random reasons. The nightly news 'the market moved lower on profit taking' or 'the market moved higher on positive news X' is just rubbish. Occasionally, there is a cause-and-effect like an unexpected interest rate change, or a better-than-expected sales figure in a key industry, but for the rest of the time, it's just random movement. The worst thing is the need to commentate on it confuses the correlation in the general publics mind, so people believe you can talk the economy up or down, which is an assertion I don't agree with.
