China's economy and stockmarket are reaching new highs and possibly overheating. Is this the end of the party?

It is of note from this article that certain Chinese alternative energy companies. . . high-flying solar names including Trina Solar, (TSL) JA Solar, (JASO) Solarfun Power (SOLF) and Suntech Power sank, with Trina down 12%.

We have all been conditioned to assume continued and massive Chinese expansion. But as I have just written for World Finance magazine, this may prove to be the illusion of our age - although I earnestly hope not. We have derived so much advantage from Chinese mass-maufacturing (not least the laptop I'm using right now) which we are on the cusp of exploiting for alternative energy.

But anthropologists tell us that mankind has an instinctive bias towards optimism and investors must never forget it.
