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 mobile advertising technologist Marchex (NASDAQ:MCHX) soared 15% today after its quarterly results and outlook topped Wall Street expectations.

So what: The stock had pulled back sharply in recent weeks on concerns over slowing growth, but Marchex's strong Q1 results -- earnings per share of $0.05 topped the consensus by $0.01 on a revenue spike of 46% -- are quickly easing those worries. Additionally, management said it expects full-year, call-driven revenue of $171 million or more, giving analysts some decent visibility into upcoming quarters.

Now what: Don't expect the operating momentum to slow anytime soon. "With the rapid adoption of mobile, consumer phone calls are fast-becoming one of the most important outcomes of mobile ad campaigns," said Chairman and CEO Russell Horowitz. "Advertisers now want a better understanding of these over-the-phone interactions. Marchex is ideally positioned to meet this new and growing market, based on our early investment in our Call Analytics technology platform and pay-for-call marketplace." Of course, with the stock now up about 180% from its 52-week lows and trading at a 45-plus forward P/E, much of that potential might already be baked into the valuation.
