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 AsiaInfo-Linkage (Nasdaq: ASIA), a Chinese telecommunications supplier, plunged as much as 13.7% after the company projected fourth-quarter revenue below the low end of analyst estimates, Bloomberg reports.

So What: AsiaInfo actually reported strong results. Revenue grew 91.5% over last year's third quarter. Per-share earnings improved 38% to $0.40 on a Non-GAAP basis. Alas, growth won't continue at that same pace.

Now What: Management sees AsiaInfo booking a maximum of $123 million in revenue in the fourth quarter, well below the $126.8 million analysts predicted in a recent Bloomberg survey. But that may be a smaller problem than today's sellers believe. Unlike peer Amdocs (NYSE: DOX), AsiaInfo trades for a fraction of its long-term annual earnings growth analysts estimate.
