Hi experts

In portfolio chapter, i am confused with beta calculations as in they have taken simple average of beta whereas weighted avg. should be used.

Pls. explain why they have taken just simple avg. of beta?

Thanks

See my first reply on page 2.

There is no logic for this. But weighted average beta is appropriate.

Yes, definitely. If in some of solved problems in PM you will find that average beta is used but you can & should used weighted average beta. There is no reason your answer has to 'match' that of ICAI as long as you have done it the right way.
