A short-term play apparently sees limited upside in Twitter.
optionMONSTER systems show that a trader bought 3,673 Weekly 42 calls expiring tomorrow for $0.11 and sold the same number of 41.50 calls at that strike for the bid price of $0.15. Volume was above previous open interest in each strike, so this is new positioning.
The trader takes in just $0.04 in this credit spread, which is the maximum profit. He or she risks $0.46 if TWTR is above $42 by the end of tomorrow’s session.
