If a portfolio is comprised of two stocks. Stock A comprises 65% of the portfolio and has a beta of 1.21. The portfolio beta is 1.119.
<h3>Portfolio beta</h3>
Using this formula
Portfolio beta=(Stock A portfolio×beta)+[(1-Stock A porfolio)× Stock B beta]
Let plug in the formula
βp = (.65 × 1.21) + [(1 - .65) × .95]
βp = (.7865) + [.35 × .95]
βp= .7865+ .3325
βp = 1.119
Therefore the portfolio beta is 1.119.
