i know the overall answer has one contract difference but i would like to know if my method is coorect anot. If i am wrong, why? Thanks so much

though your method has been discussed before - please note that you will NOT get full credit from the CFA graders. Follow the method in tthe book. Use this shortcut to determine if you are close.

If you have ONLY a couple of mins at the end of the AM session to do the problem - use your shortcut

Thanks alot cpk123

I don’t see why he wouldn’t get full credit.

They’re doing allocation first, beta second; he’s doing beta first, allocation second.

Frankly, I’d be surprised if you didn’t get full credit for doing them together, by changing the dollar beta:

Hi S2000 Magician, Thanks for your help.

It seem that the concept is right, but i am not confident of it.

My pleasure.

In that Q7 of the mock, one could answer for the equities 241.67+221,52= 463 and not 464.

Would that be correct? to me, it makes more sense since he achieves both with higher accuracy.
