1.
What are the prospective payoffs for the portfolio, when the market has
(a) large rise (b) small rise (c) stagnant (d) small fall (e) large fall

Under uncertainty which asset class is most favorable?
3.
With perfect information which asset class(es) becomes favorable with each changing market conditions?
4.
What is the expected payoff with perfect information?
5.

RBI gives regular forecast indicating either positive or negative economic growth in the coming quarter. Using a relative
frequency approach based on past information it has been observed that:
P (positive | large rise) = 0.8
P (positive | small rise) = 0.7
P (positive | small fall) = 0.4
P (positive | large fall) = 0
P (positive | stagnation) = 0.5
Given the above information, calculate the following revised probabilities:
P (large rise | positive) = ?
P (large rise | negative) = ?
P (small rise | positive) = ?
P (small rise | negative) = ?
P (stagnation | positive) = ?
P (stagnation | negative) = ?
P (small fall | positive) = ?
P (small...
