In thinking about this a bit further, I will give you an example. I entered the MYM at a certain point on Wednesday evening. My target was set to right around the ~300 point profit mark, which was ~35K. The thing got to within 100 points of target on Friday morning.
Now, I could have set a trailing profit stop on that when it went 200 points in profit. But that was not my target. I am letting that winner run.
So what happened? Currently it is in the opposite direction, DOWN 300 points.
So. What should I do? Cut the loss now? Is it early? Is it late? What it comes down to in my mind is that there is only one fast and hard rule when it comes to trading an INDEX. Set your target and ride the waves.
I think that is a disadvantage I experience when getting into conversations like this, because I never focus on individual stocks. An individual S&P stock could collapse to zero in a week while in that same week the index itself just keeps going up.
Hey uh, Ken? Don't let mIe get into conversations like this anymore. You trade single-stock names, I do not. So you are better-suited to make sense on these things.
