"This has all the ingredients of an IPO 'hit'," Irv DeGraw, research director at WorldFinanceNet.com said in his weekly report. "Expect a first-day moonshot, followed by aftermarket appreciation."
Efficient Networks sells its products to network equipment vendors and DSL network service providers. Efficient's customers include BellSouth Corp. (NYSE: BLS), Covad Communications Group (Nasdaq: COVD) and Hong Kong Telecom.
Analysts say the IPO was boosted by its relationship with Texas Instruments Inc. (NYSE: TXN), a principal stockholder in Efficient Networks.
Efficient competes with 3Com Corp. (Nasdaq: COMS), French telecommunications group Alcatel and Cisco Systems Inc. (Nasdaq: CSCO).
Efficient Networks isn't the only DSL company planning an IPO this week.
