It is not like investors really need any more evidence that the Internet infrastructure sector is scorching right now, but they got it from Internet traffic-management company F5 Networks on Wednesday. Shares of F5 Networks climbed more than 38 percent on Wednesday, gaining 37-7/8 to 137 after the company reported fourth-quarter net income of $2.3 million, or 11 cents per share. Analysts had expected the company to lose five cents per share.
Some analysts view hardware, software and traffic management as the three key parts of Internet infrastructure, and F5 Networks looks like a leader in traffic management. F5 Networks has been one of the top-performing IPOs of the year. The company went public at just $10 in June.
