No it isn't the EMA 8 that is the problem. Here is ATHR and you can see that the EMA 8 is just fine - I happen to love this chart - I'm printing it out and putting it on my wall.
This is a dipster's holiday. If you see a chart that looks like this again and you don't buy the stock at the Doji-like candle you are probably just pretending. In this instance the crossover just reinforces the deal.
