I know it is a terrible thing to say, but I saw it coming. I was looking at the chart yesterday (literally yesterday) and just like with one of my other stocks TWD, the stock was way outside the bollinger bands in the weekly chart. The EMA-9 line crosses at around 0.70 so that was the level which one could have expected to see a correction towards. Unfortunately I did cash in on my TWD stocks but not on GNH, wrong choice so far!
Let's not forget that GNH gained about 400% in four months. We're now very close to the 38.2% fibonacci at 0.68 which should serve at least as an intermediate support level. I am not worried but then I am never worried because I do not put all my eggs into one basket (helps me sleep at night).
Watch the orange line (EMA-9) for the time being. This chart quite nicely shows that we had a similar situation happening from 75c back to 45c or so, also pretty much a drop to the 38.2% fibonacci level. These are quite healthy corrections for such rapidly rising stocks and are nothing to worry about. Don't look at this as some bad interpretation of the news that came out today. If you're a professional trader, you look at charts rather than news. And if you see a chart that is so far outside the bollinger bands, you take profit and let the stock cool off before you re-enter. No worries.
