I'm not surprised by the action today. If the GERN board on Stocktwits was an indication of retail trader sentiment, then everyone was ready to sell the news and crowded the trade.
I think the until the continuation decision is announced, the price will likely swing between low 4s and mid 3s with maybe a spike and/or a dip outside that range just because.
But anything can happen and news can come out of nowhere. I think the best thing to do at this point is just hold and wait for the inevitable continuation decision.
