Last month, you found the tangency portfolio and constructed your optimal complete portfolio, which is a mix of the tangency portfolio and the risk-free asset.
Today new information about the stock market is released and affects the moments (mean, variance, and covariance) of all stock returns.
You update your belief on the moments, find the new tangency portfolio, and re-construct your optimal complete portfolio, given new information.
The risk premium of the updated tangency portfolio is 1.42 times the previous one, and the volatility of the updated tangency portfolio is 1.1 times the previous one due to the new information.
If the weight on the tangency portfolio was 0.6 and 0.4 on the risk-free asset in your previous optimal complete portfolio, what is the weight on the updated tangency portfolio in your re-constructed optimal complete portfolio? Assume your attitude to risk ( = price of risk) remains the same.
