A large trader is looking for a big move up or down in Texas Instruments.
optionMONSTER’s Depth Charge system shows that 10,000 April 42 puts were bought for the ask price of $2.49. This is clearly a new position, as the previous open interest at that strike was just 237 contracts.
Just afterward, 510,000 shares of TXN were purchased for $41.85. Given the that the delta of the puts was -0.51, the combination of stock and options creates an overall position that is looking for a sharp move in either direction and/or for the actual volatility to be greater than that implied by the option price.
