wink26 Wha? A portfolio that has exposure to a one factor is diversified?

I don't agree with I.
jay1 yes you can have well-diversified portfolios that are sensitive to one factor. Check the example 11 of the reading. Being well-diversified means there is no unsystematic risks. That's it.
dblueroom The CAMP is an example of one factor portfolio. Only market risk is considered and priced, as compared to multifactor APT, asset return has exposure to multiple factors.
StJohnDale I think this question belongs in the next section?
