Citigroup trader banks on more gains

Citigroup doesn't need to hit new highs for traders to make big money.

Option activity was rocking in the financial giant yesterday, with more than 64,000 calls outnumbering fewer than 31,500 puts. One big trade stood out in particular on optionMONSTER's Heat Seeker system, as 2,004 April 43 calls were sold for $2.30 and twice as many May 46s were bought for $1.09 and $1.10, indicating that an investor is rolling a long position to a higher strike price one month later.

Long calls lock in the price where traders can buy shares, so these contracts will can generate significant leverage if C rallies in the next month. Rolling the contracts up in price and out in time indicates that the trader is confident that more gains are on the way. (See our Education section)

C rose 2.54 percent to $45 yesterday. It's still almost $3 from its 52-week peak of $47.92, even as other financials run to new highs with major equity indexes in record territory.
