Why are the Makets harder to trade NOw??

Anyone who trades the stock market knows that it's much more difficult today than ever and we have so many tools to analyze what's going, etc. I thought this remark from Don Worden, whose company develops charting software, is prescient.

"I think we probably have more traders trying to "profit off the news" than has ever been the case in history. Consequently the market gets kicked around from day-to-day by transitory events of fleeting significance. Traders seem quick to jump on events that have no direct connection to even the short-range market outlook. For example, one day's fluctuation in the price of crude oil or in the number of casualties in Iraq offer little valid insight into how the market is likely to be affected a month from now, or two weeks from now, or even next week. But admittedly, playing the micro-moves in the market can yield frequent profits to a skilled, say, hedge fund operator. It doesn't take much thoughtfulness to play the market's fits and starts. "
