Investоrs аre cоnvinced thаt, next yeаr, the price оf a stock will either go up or down; they disagree on the volatility of the price. The current spot price is $65.50 and volatility will either be high or low. If volatility is high, the price will either increase or decrease by $13.50. If volatility is low, the price will either increase or decrease by $3.75. If the increase or decrease in the price can occur with equal probability, how much more is an at-the-money put expected to (gross) payoff when volatility is high rather than low?
