Answer:

Beta= 1.478

Explanation:

Giving the following information:

An individual has $20,000 invested in a stock with a beta of 0.4 and another $65,000 invested in a stock with a beta of 1.8.

To calculate the portfolio beta, we need to use the following formula:

Beta= (proportion of investment A*beta A) + (proportion of investment B*beta B)

The proportion of investment:

A= 20,000/85,000= 0.23

B= 65,000/85,000= 0.77

Beta= (0.23*0.4) + (0.77*1.8)

Beta= 1.478
