I shorted a $19 put on HAL when it was trading at $19.50: 70 contracts @ $5.40 each contract. Price of underlying is currently $18.87 and they expire today. Im having a hard time finding a clear answer as to what happens if I dont exit my position before the market closes today. I wouldnt be too upset about owning Halliburton @ $19/sh but am i correct that i will be responsible for buying 7,000 shares? 70 contracts each representing 100 shares...7000x$19=$133,000?
