An investment company is studying the creation of a financial security that will bear the symbol CSI and will give right to a payment in one year of $150 in the pessimistic scenario and $260 in the optimistic scenario. The risk-free interest rate is 3%. Consider the two financial stocks ATX and BLU whose prices in the absence of a learning opportunity are as follows:

Titles	Market price today in $	Flows in 1 year according to the scenario in $
		Pessimist	Optimist
ATX	55	35	70
BLU	95	80	120

a) Is it possible to replicate CSI by combining ATX and BLU? b) What is the price of CSI stock if there is no arbitrage opportunity? c) If the probability of realization of the pessimistic scenario is 40% and that of the optimistic scenario is 60%. What is the expected return on the CSI asset? What is the risk premium? d) If the risk premium of CSI stock is 0.75%, is there an arbitrage opportunity?
