If you're a trend trader definitely-you've got an up draft in a down trending stock price. You short & hope the down trend continues. Whether the share price continues lower is any ones guess. The trend is your friend. Good luck.
I'm guessing it's still above $400 because its the most profitable company in the world. that still carries some weight. however it has been overbought in the very short term and will see a slight pullback, possible back to $440 but not much lower
