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: Wireless network equipment specialist Aruba Networks (Nasdaq: ARUN) surged as high as 11% in early trading after posting better than expected quarterly results.

So what: Thanks to rebounding demand across all of its product lines, Aruba managed to swing to a first-quarter profit of $2.1 million, reversing an ugly loss of $24.7 million just one year ago. In particular, the ever-growing popularity of mobile devices like tablets and smart phones helped drive strong sales of its networking equipment.

Now what: While Aruba has more than doubled over the past year, there might be plenty of room left to run. Although the company didn't provide future guidance, Aruba should continue riding the powerful wave of a growing enterprise WLAN market. Given Aruba's relatively small size, however, I'd still have to make that bet in basket with its larger foes Cisco Systems (Nasdaq: CSCO) and Motorola (NYSE: MOT).
