Two traders are considering purchasing a European call option on a non-dividend paying stock with an annual volatility of 35%. The traders have different views on the underlying stock’s future performance: Trader A thinks the stock price will increase by 6% over the next year. Trader B thinks the stock price will increase by 12% over the next year. Both traders will p rice the option using a binomial tree, with each time step equal to 1 month. The option expires in 1 year and the risk-free rate is 2% per year. What will each trader use in their respective models for the risk-neutral probability of a downward movement in the stock price over the first-time step?
ATrader A will use 50.00% and Trader B will use 40.81%.
BTrader A will use 50.05% and Trader B will use 59.19%.
