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 SouFun Holdings (NYSE: SFUN), which bills itself as "the leading real estate and home furnishing portal in China," soared as high as 11.6% above last night's closing prices after it reported its first quarter as a publicly traded company.

So what: SouFun is obviously in the rapid-growth phase of its young history, reporting 83% stronger sales year over year and doubling its operating income. Non-GAAP earnings also came close to doubling if you back out the year-ago period's generous tax benefits.

Now what: Before jumping into this stock, make sure that it's actually the real estate marketer you're interested in. The ticker is easily confused with Chinese solar panel manufacturer Solarfun Power Holdings (Nasdaq: SOLF) and SFUN used to be attached to Israeli memory chip designer Saifun Semiconductors before that company was acquired by Spansion (Nasdaq: CODE). SouFun has only seven active CAPS picks at the moment and could use your input to qualify for its first CAPS rating.
