The Internet Infrastructure HOLDRs ( IIH) was one of the top performing exchange-traded funds Wednesday, courtesy of rising holdings VeriSign ( VRSN) and Openwave Systems ( OPWV).

VeriSign was rising 5% after CEO Stratton Sclavos abruptly resigned after 12 years of holding the position.

Meanwhile, rumors of takeover bids pushed Openwave Systems higher by 5%. Rival InfoSpace ( INSP) was gaining after word that Spanish company LaNetro Zed may acquire the company for $1 billion.
