Quote from piezoe:
TinGull, one of the hardest lessons I had to learn is that the market does not behave rationally from day to day. It is only rational over the long haul. Stocks can go up because they are going up, and they can go down because they are going down. No other reason is needed. Therefore, one has to learn to just accept what's happening and not try to second guess it, or predict what will happen next.
This is both the most important and the hardest "trading" lesson to learn. It goes against human nature, and that's what makes it so damn hard to grasp. Follow "tradequicker's" advice.
We are all brought up to believe that the stock market is a function of the economy. And that is absolutely true, but only on average over time. The day to day market marches to a different drummer. So if you are a trader, just observe what's happening and act accordingly. Don't try to rationalize what is going on. It can't be rationalized because it is often not rational. Forget those pundits that say the market went up or down because of such and such. They haven't any more clue to what's driving the market than you or i.
