Quote from NoDoji:
For the long term investor, fundamentals and news that affects the fundamentals of a company are very important. Long term investors generally hold much smaller positions than day traders and close their position at an 8-10% loss.
Day traders need only focus on the price action and ride the coattails of whichever side is currently winning. If one side has been winning for a long time, joining the other side can work well as long the other side demonstrates signs of weakness. Assuming the other side will become weak because they've been strong too long is a dangerous game, best played with very tight stop losses.
Every one of my large losses came from thinking about fundamentals or about what should happen based on news, or based on a very strong move having to reverse when I think it should reverse.
I trade crude oil futures and when economic news comes out I don't even care what the news is because the price action tells me the more important information which is how the larger market interprets the news. When the crude inventories come out, I really don't want to know if they're bullish or bearish numbers, because that never seems to matter when all is said and done and, if anything, knowing those numbers are bullish or bearish has often kept me out of very profitable trades. Thinking price has run too high or too low has also kept me out of very profitable trades.
I'm still working to overcome these biases, and as a day trader the less I pay attention to the news and the fundamentals, the more profitable my days are.
Very true. The two don't mix well.
