If your swing trading than news driven moves are more suspect of failing since the uninformed mob trades off of news and is driving the move, while the smart money is usually selling into this. There are some news exceptions like earnings that can break a stock out of a pattern on big volume (50%-300% of avg volume) and send the price into a sustaining directional move for days/weeks/months. Bottom line, most of my swing trades work best when the move proceeds the news - not when the news creates the move.
