APC – Anadarko Petroleum Corporation – Trading in longer-dated call options on Anadarko Petroleum this afternoon indicates one options strategist is expecting shares of the independent oil and gas exploration and production company to rebound significantly by expiration in January 2011. APC’s shares rallied 1.5% at the start of the trading session to reach an intraday high of $43.70. However, as the day progressed, shares lost momentum and are currently down 3.90% on the day at $41.38 with 45 minutes remaining before the closing bell. The long-term bullish player appears to have enacted a ratio call spread, buying 2,000 in-the-money calls at the January 2011 $40 strike for a hefty premium of $10.30 apiece, and selling 4,000 calls at the higher January 2011 $55 strike for a premium of $3.60 each. The net cost of the spread amounts to $3.10 per contract. Therefore, the trader is poised to profit should shares of the underlying stock rebound 4.15% to surpass the effective breakeven price of $43.10 by January expiration. The investor stands ready to accrue maximum potential profits of $11.90 per contract in the event that APC’s shares surge 32.9% from the current price of $41.38 to settle at $55.00 by expiration day.
