QIHU and a number of Chinese moving up/down so fast. Using puts to hedge if you are so sure since options have a premium costs and timing issue.
When a stock has great fundamental, going long with patience is better to me. Remember when it was at $85 or so, it came down a lot then well, went up way above high then due to good fundamental. Look at the charts of good growth stocks, seem to me if we buy slowly then over time we will make good money.
Chinese stocks are being manipulated in a big way. Sadly. I agree with bambooze.
