So, let's take a look if we could at the chart action and get a feel for where you're at. You're in the stratosphere at $3642.5. The market did a real nice job of hanging on near that $3380- $3400 level, and it has moved straight on up.
You can see that, and I'm going to repeat: Nothing goes in a straight line forever, so if you don't know how to take money off the table, learn to do some. Does that mean I'm bearish? Not at all, but you don't make money unless you take the money off the table and this is a heck of a run the market has had.
