A pair of Silicon Valley companies enjoyed double-digit gains on their first days of trading Friday after pricing their initial public offerings (IPOs). Shares of Santa Clara-based Infoblox, a maker of network automation software, gained 33% on the day after pricing its shares at $16 late Thursday. Sunnyvale-based security software developer Proofpoint, meanwhile, saw an 8% bump after pricing its shares at $13. The debuts came a day after San Francisco-based Splunk, a maker of software providing users with real-time operational intelligence, more than doubled its market cap to above $3 billion on its first day of trading.
