Looking at weekly chart we can observe ESPR
history, that can be summarized in 2 double tops and a rising channel
. At the moment we have broken out the channel to the upside, gaining about 30% during the past weeks. A significant level for this stock
could be the 20$ area, that is the higher hight and it wasn't touched from August 2013
. If you have a look to StochRSI you can observe how it's very clear on all the moves of this stock
. Now we are in an overbought condition and the signal line is converging to the overbought area following a triangular pattern that will break inevitably to the downside. Probably there is still room for one more leg up to reach a possible peak on the 23-24$ area, but i'm looking for a strong retrace.
Good luck for your trading
