$PFE price action has moved like the $WYNN chart before it started moving very well to the upside.
Price has broken out of its long wedge, hit the 50 Day MA and pulled back to test the outside of the wedge, the price maintained support on the outside until hitting the 0.78 Fib and then bounced again.
So the 50 Day MA is the big resistance level for $PFE to break above, getting above $28.30 and holding support above this level will be a serious sign that the bottom may be in now.
