MasterCard surged to a new all-time high this morning, and one trader is betting that those gains will stick.
optionMONSTER systems show that a block of 4,435 of the November 83 puts was sold for the bid price of $1.06. The previous open interest was a mere 3 contracts, so this is clearly a new position.
The put seller keeps the $1.06 credit and is looking for MA to stay above that $83 level in coming weeks. If the stock falls below that strike price, the trader would be on the hook to buy shares at that level.
