Compared with a long straddle on the same underlying, a long call butterfly spread is best described as which of the following?

A long call butterfly has a loss limited to the net premium paid and profits when the price finishes near the middle strike. It suits a view of low volatility, whereas a long straddle profits from large moves.

  1. AA position that profits from large price moves in either direction, with unlimited upside
  2. BA position with limited loss equal to the net premium that profits if the price stays near the middle strikeCorrect
  3. CA position with unlimited loss if the price stays near the middle strike
  4. DA position that profits only if the price rises above the highest strike

Explanation

A long butterfly costs a net premium, which is the maximum loss, and has its peak payoff at the middle strike. A long straddle is the opposite, profiting from large moves. The butterfly is suited to low expected volatility.
