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 helpfully titled China Real Estate Information (Nasdaq: CRIC) jumped sky-high yesterday and then came back for an encore, gaining as much as 13.3% amid very heavy trading.

So what: Lacking solid news out of CRIC and its closest rivals, this looks like another spontaneous jump. This small cap is thinly traded, with even thinner coverage by Wall Street analysts, and is prone to wild swings at the slightest hint of trading attention. It's sort of funny, because a very material partnership deal with Baidu (Nasdaq: BIDU) last week hardly moved this stock at all.

Now what: All that said, loosely related Internet information wrangler Bitauto (Nasdaq: BITA) also jumped like a cricket today on news that Tiger investor Chase Coleman took a very large position in that stock. These things can cause ripple effects among Chinese Internet stocks, and may have contributed to this particular swing. If that's the case, don't expect the good times to last -- What Coleman thinks about Bitauto has next to no bearing on the value of China Real Estate.
