I agree with Naz these stocks are perfectly playable, but I would add some experience and capability is necessary.
One element must, as he says, be adjusting position size to control $ risk when they are so highly volatile. Another is stepping back the time frame, e.g. looking at 15 min candles. Yet another is thinking about the overall situation, e.g. the pre-market rush to the critical $200 level and the later attempts to breach it all failed those tests, so the probability of profit taking increased sharply. And how about the gap players wanting to close it?
Of course there are people who happily say that news doesn't matter. I don't agree, the reaction to the news does matter and is often tradeable and I make a good third of my income from the way I play them.
As for GOOG last night, hey, didn't the Nana Netlife story have an influence? Didn't the news probably cause the late sell off?
In my view, you need an integrated thoughtful approach and then even the wildest of stocks become readable and tradeable.
