David Russell (david.russell@optionmonster.com)

Nearing the halfway mark in today's session, here are the individual equity names with the most call and put buying on optionMONSTER's ActionTracker data system.

Cisco Systems (CSCO): Some 52,000 June 25 calls were bought, mostly for $0.19 to $0.28, as investors look for the tech giant to keep climbing. CSCO rose 1.25 percent to $24.18.

Phillips 66 (PSX): More than 14,000 May 65 calls were purchased, mostly for $0.35, against open interest. The investor probably closed an existing short position, allowing them to stay long shares through expiration today. PSX rose 1.72 percent to $64.94.

Facebook (FB): An even 10,000 July 22 puts were bought for $0.17 as investors brace for potential downside in the social-media stock. FB rose 0.91 percent to $26.37.

Disclosure: I own CSCO puts.
