If option traders are right, U.S. Airways may be preparing to roll down the runway and fly higher.
OptionMonster's tracking systems showed heavy activity in the January 15 calls yesterday, plus the February 16 calls. The big trades were selling in the January 15 calls for $0.63 and buying in the February 16s for $0.85.
Calls lock in the price investors must pay to buy shares, so they can generate significant leverage when their underlying stock moves. But these options also lose value as expiration approaches, so yesterday's trader rolled a January position forward by a month to avoid that time decay.
