An arbitrage firm (A) notes that the bidder (B) whose stock is selling at $40 makes an offer for target (T) selling at $65 to exchange 2 shares of B for one share of T. T rises to $75; B drops to $38. A sells 2 B short for $58 and goes long on T for $55. Six months later the deal gets abandoned. B's stock price goes to $41. T's price goes down to $ 70. Assume that the arbitrage firm closes out the position. What is A's dollar return? What is A's percentage annualized return?
