ArcelorMittal (MT): Blocks of 13,000 contracts each traded in the August 13 calls and the August 14 calls. Volume was below open interest, which suggests an existing bullish call spread was closed. MT fell 3.25 percent to $12.20.
Micron Technology (MU): Some 5,500 August 14 puts were bought, mostly for $0.47, but volume was below open interest at the strike. MU fell 1.23 percent to $14.
