Exercise

# Minimum variance portfolio weights

A portfolio invested in two stocks is not realistic. A more realistic example is to consider an equity portfolio invested in two diversified exchange traded funds (ETFs), like an ETF invested in US stocks and an ETF invested in EU stocks. In this exercise you need to use the GARCH estimation output available as `usgarchfit`

and `eugarchfit`

to compute the weights of the US ETF in the minimum variance portfolio invested in the US and EU ETF using the formula

Instructions

**100 XP**

- Compute the standardized US and EU returns, together with their correlation.
- Compute the covariance and variance of the US and EU returns.
- Compute the minimum variance weights and plot them.
