The market is a a remarkable psychological beast.
If you find yourself asking questions such as …
“How much higher can it go?”
“How much lower can it fall?”
Not only will the market show you, it will surprise you.
“That stock just went from 20 to 50, it can’t keep going up can it?”
Next thing you know, it’s at 80.
That’s why when a stock is on the move, I go with it.
However, it’s probably moving around pretty fast so I use options to limit my risk.
