Only a 100 or so shares in AH. I can only speak for how I would have traded it on a swing. I'd have jumped in and sold half when it set a new 52 week high. I'd have sat on the rest and as long as we stayed level I'd have kept in play and looked for a break down or a continuation move. I saw the breakdown last week despite the EOD paints. We had some support at around .35 so that would have been my last exit.

As for stop orders, that could definitely be part and they would trigger at once even accross multiple traders. I never use them unless I am not going to be able to watch the action and then only rarely. I used them when I was new in trading but after getting burned by numerous "stop loss raids" I stopped using them.

I don't think this was a stop loss raid for those wanting back in. It was IMHO just selling though for me it does not change my position.

FULL DISCLOSURE: I sold 20% of my holdings the day of the run up. I put in 4 repurchase orders starting at .35. That one filled the first time we pulled back but finished strong anyway. I pulled my other buys today because I think we will still move down. KRY - TSX closed on the low on very high volume.
