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.

Microsoft (MSFT): Some 34,000 July 27 calls were purchased, mostly for $5.70, but volume was below open interest. That suggests an investor closed a short position, and reflects a belief that the software giant is going higher. MSFT fell 1.33 percent to $32.66.

Micron Technology (MU):  A block of 32,000 October 12 calls was purchased for $0.34. The October 9-October 7 put spread was sold barely a minute later, so it appears the investor is looking for higher prices. MU fell 2.02 percent to $9.23.

Marvell Technology (MRVL): More than 7,000 May 11 calls were bought for $0.35 as traders position for a move higher. MRVL rose 1.58 percent to $10.93.
