WTH is Pairwise Correlations? Q47 CFAI 2017 AM Mock

Can some one explain WTH they mean by low pairwise correlation? does it mean with one other asset class in this case? This AM exam was worded so weird, I feel bad for those who’s first language is not English if the real exam ends up like this…

If you have, say, four asset: let’s call them A, B, C, and . . . you’re way ahead of me . . . D.

Pairwise correlations (which, as you well know, are the only kinds you can have) are the correlations (of returns, most likely) between:

  • A & B
  • A & C
  • A & D
  • B & C
  • B & D
  • C & D

Low ones would, of course, mean that they’re all rather close to zero.
