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 Borderfree Inc (NASDAQ:BRDR) fell 15% Thursday, despite the cross border e-commerce specialist releasing better-than-expected first-quarter results and guidance.

So what: Quarterly sales rose 3% year over year, to $26.5 million, which resulted in an adjusted net loss of $0.1 million, or $0.01 per share. On a pro forma basis -- as if all preferred shares converted to common shares outstanding as of Jan. 1, 2013 -- Borderfree's adjusted net loss was $0.00. Analysts, on average, were looking for a significantly wider loss of $0.09 per share on lower sales of $25.42 million.

For the current quarter, Borderfree expects revenue of $30.1 million to $30.7 million, with an adjusted net loss of $0.03 to $0.04 per share. By contrast, analysts were expecting a wider $0.06 per share loss on sales of just $30 million.

Finally, Borderfree sees full-year 2014 revenue of $141.3 million to $143.5 million, with adjusted net income of $0.09 to $0.11 per diluted share. Once again, Wall Street's models weren't nearly as optimistic, calling for a break-even year on sales of $138.06 million.

Now what: Perhaps the market was hoping for a bigger beat. But at least some of the pullback can also be chalked up to a broader retreat in Internet-related stocks, as the tech-heavy Nasdaq Composite Index plunged another 0.4% today.

Borderfree also doesn't exactly look cheap trading around 61 times next year's expected earnings, but that's not terribly alarming for a company on the cusp of profitability. With the stock now trading 45% below its post-IPO close in March, I think Borderfree's latest plunge might just represent a perfect opportunity for long-term investors to open -- or add to -- a small position.
