Shares of Cisco Systems were crushed in after-hours trading Wednesday after the technology company posted disappointing earnings results and CEO John Chambers expressed frustration in his inability to tell where the economy is right now.

When Cisco started to trade lower, so did the entire technology space. So how do you trade this sector in the wake of Cisco's earnings?
