It is a little painful. I can't say with certainty what goes on in the minds of those deciding to buy or sell. My thought is that the big money takes time to analyse a PEA and get the approvals/concensus to start accumulating. I have seen this before where it takes a week or two for a stock to start to move in the right direction after a positive announcement - maybe longer in summer vacation season. Meanwhile we have a lot of small investors - some perhaps in too deep, who were expecting a big move up with every good news announcement and panic sell when the price doesn't move as they hoped on the news release.
I think the story is still good, even great. I added another 25% to my holdings this morning.
