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 RealPage (NASDAQ:RP) got hammered today, down by 17%, after the company reported earnings with uninspiring guidance.

So what: Adjusted revenue rose to $83.2 million, shy of market forecasts that were calling for $84.2 million. Non-GAAP earnings per share was right on target, though, at $0.12, so nothing to call home about there. The real pessimism centered on guidance.

Now what: Guidance for the current quarter expects revenue in the range of $85.5 million to $87.5 million. Even the high end of guidance would fall short of the $89.4 million that investors were expecting. The bottom line could potentially meet the consensus of $0.14 per share if RealPage stretches a little bit.
