A Big Call Spread Buyer in YPF

YPF SA, an energy company that engages in the exploration, development, and production of crude oil and natural gas in Argentina.  I have traded this stock in the past, but I currently do not have a position.  Today we saw a trader buy 2,000 of the Jan 2015 30-40 bull call spreads for $2.85. This is a cash outlay of over $500,000.  A trader sees that YPF is breaking the Ichimoku Cloud on the daily chart and thinks it can move higher. This trader is likely expecting a slower more sustained move higher in YPF. If they were expecting a parabolic move higher they would have bought outright calls instead of call spreads. This is a bullish trade and this trader will make almost 300% returns if YPF closes above $40 on Jan 2015 expiration.
