Answer: 1.02
Step-by-step explanation:
The Portfolio Beta will be the weighted average of the betas of the individual stocks in Portfolio 1.
Portfolio Beta = (weight in G * beta of G) + (weight in H * beta of H) + (weight in I * beta of I) + (weight in J * beta of J)
= (0.25 * 0.45) + ( 0.25 * 0.82) + ( 0.25 * 1.14) + ( 0.25 * 1.66)
= 0.1125 + 0.205 + 0.285 + 0.415
= 1.0175
= 1.02
