Answer #1

ans A There are more than one possible path , actually 4 of them . the average price across the 4 paths is roughly 101.50

we can use this to price the option .take risk free rate t =1/12 and time =1/12.

Ans B to protect my stocks i would need protection against prices falling. So i would look for an option with strike price below the current spot price. So if the stock falls i can cushion the fall to the extent of Spot - strike price However this may not protect enough is the closing price is lower than strike price. The second method is to sell a Covered Call option at a price which is at least 1% ( risk free rate ( more than spot price .This would mean the cash from selling the option is assured and will protect the stocks in hand t a certain extent.  

Ans 3 - Considering Asian options has lower volatility as it is an average of 3 data points the  prices should be lower than European which is at a fixed price and a a particular instant of time. in B&S option pricing if the Sigma value is lower the formula will throw up a smaller number so lower prices.
