Largest option trades in equities


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.

Thermo Fisher Scientific (TMO): An investor sold 10,000 September 90 calls for $3.10 and purchased an equal number of March 100 calls for $3.10. They also sold 10,000 March 85 puts, suggesting a simple long position in the front month was exited and rolled it to a bullish combination strategy expiring in the first quarter of next year. TMO rose 0.04 percent to $92.22.

Microsoft (MSFT): A block of 10,000 January 33 calls was bought for $1.48 and equal-sized blocks were sold in the January 28 puts for $0.51 and the January 36 calls for $0.55. While volume was below open interest at all three strikes, the trade appears to be a bullish three-way strategy with significant leverage on a move to $36 by expiration. MSFT fell 1.23 percent to $32.24.

Digital Generation (DGIT): Some 8,500 August 7.50 calls were bought, mostly for $5.80 and $6.20. Volume was below open interest at the strike, so traders are probably exiting short positions as the stock explodes higher. DGIT rose 27 percent to $13.13.
