I have a question about the s&p 500.
How do most of you know when the s&p 500 is going to make a sustainable trend up or down?
I'm searching for a kind of method or analysis that ignores short term up (in a downtrend) and short term down (in an uptrend) trends in the s&p 500.
So when the s&p 500 is going down and we have a few up days and after that it goes back down, it was a kind of false signal, how do I avoid such false signals?
All insights are welcome
