Applying for AM in Asia. Study Asia or U.S. market or both??

Hey guys. I'm a senior applying for FT Asset Management positions at BBs in Asia. I'm originally from Asia but I''m going to school in the U.S.

I understand that stock pitches and a good understanding of the markets are crucial for AM interviews. I also realize that my preparation time at this point is quite limited. So I was wondering if anyone knows in this case if I should focus on Asia stocks, or will I be OK pitching mainly U.S. stocks, or do I need to know a good deal about both markets?

Thanks!
