Shares of Stamps.com (NASDAQ:STMP) soared as much as 16.7% higher on Thursday, following the release of solid fourth-quarter results. At 2 p.m. EST, the stock had settled down to a smaller but still impressive 11.7% gain.
The shipping software and online postage specialist saw top-line revenue rise 25% year over year, landing at $132.5 million.

Stamps.com enjoyed a fantastic holiday season for online retailers. The company supports printing shipping labels for the USPS and 35 other shipping services, including several of the mailing solutions Amazon.com (NASDAQ:AMZN) runs on its own. So a good e-commerce season is great news for Stamps.com.
Moreover, the company is only dipping its toes into international waters so far. Modestly sized service launches in Canada, Australia, and the U.K. should serve as test markets for a worldwide expansion over the next few years. This way, Stamps.com's addressable market will grow from a $90 billion domestic opportunity to a $230 billion worldwide market.
It's not surprising to see Stamps.com shares soaring on these good tidings. The stock has now gained a market-beating 64% over the last year with a five-year return of 730%.
