Consider a portfolio of asset 1, 2 3 and 4 with composition described by the following vector of weights:

Asset 1	30.00%
Asset 2	25.00%
Asset 3	25.00%
Asset 4	70.00%

Use the following data on the four assets to answer the next four questions on the moments of the portfolio distribution:

Variance-covariance matrix () of the excess-returns on the four assets:

0.64%	0.53%	0.45%	0.41%
0.53%	0.48%	0.40%	0.37%
0.45%	0.40%	0.36%	0.33%
0.41%	0.37%	0.33%	0.32%

Vector of asset mean excess-returns ():

0.50%

1.50%

What is the weight of the first asset in the tangency portfolio of the four assets?

1. -300%
2. -200%
3. 20%
4. 50%
