Similar to my recent SGMO idea, my view is that aVWAP support, 50% retracement and 50 day EMA support make a strong case that a relative low is in and higher prices are soon to come. For ALPN, the aVWAP cluster from recent significant lows/highs all cluster in a tight range in the mid 11s, which is right where the stock reversed. Likewise, if the stock goes below that blue aVWAP cluster area I would be forced to revise my buys thesis.
