This is a "return to normal" phase pushed by bulls who are trying to reclaim losses incurred from buying at the top last month. I'm guessing buy support will break before we can push to another ATH.
I'm not ruling that out as a possibility, but there was no basis for the crash other than misinterpretation of the news out of China. Now that people are getting straightened out on what it actually meant, and we're getting some more positive news (Paypal, hao123.com), I think things are feeling bullish.
