Suppose you create an optimal risky portfolio investing 60% into a SP500 ETF, and 40% into a European ETF. This optimal risky portfolio has an expected return of 9.46% and a volatility of 16.21%, and the risk-free rate is 2.8%. With your degree of risk aversion, you compute you should invest 60.7% in the optimal risky portfolio, and the rest in the risk-free rate. In the end, your portfolio will be made of the SP500 ETF, the European ETF, and the risk-free rate. What will be the weight of SP500ETF in your complete portfolio? (Give your answer as a percentage with 2 decimals, e.g., if the answer is 0.345224 (or 34.5224%). enter 34.52 as your answer.)
