Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of Chinese mapping service AutoNavi Holdings (Nasdaq: AMAP) got lost today, falling as far as 10.6% on rather average trading volume.

So what: This one's a head-scratcher. There's generally very little going on in AutoNavi's neck of the woods.

Now what: AutoNavi has no news of its own today and steady or rising prices on Chinese digital info specialists SINA (Nasdaq: SINA) and Baidu (Nasdaq: BIDU) show that the Middle Kingdom's Internet bubble didn't pop today. It looks like a large investor or two simply decided to take its capital and go elsewhere, though even that theory lacks support from the heavy volume you'd expect to see. If you're investing in China-based, digital information micro-caps, you're a braver Fool than I.
