ARWR has seen its stock go from around $70 to about $42 as of 1/30/2020. A lot has been said about the short attack but I think this is just normal re-tracement. Using FIB, we can expect it to settle around $38 and $29. I will consider picking up shares for the first time there but will also watch for the GAP at around $20 if it breaks $29.
