NEW YORK ( TheStreet) -- SBA Communications (Nasdaq: SBAC) is trading at unusually high volume Thursday with 4.3 million shares changing hands.

SBA Communications Corporation owns and operates wireless communications towers primarily in the United States, Canada, Costa Rica, El Salvador, and Panama. TheStreet Ratings rates SBA as a hold. The company's strengths can be seen in multiple areas, such as its largely solid financial position with reasonable debt levels by most measures, solid stock price performance and impressive record of earnings per share growth. However, as a counter to these strengths, we find that the growth in the company's net income has been quite unimpressive. You can view the full SBA Ratings Report.
