Equity readings 39 and 40...

Noticed there are no EOC ?'s for eqy readings 39 & 40, Porter’s five forces and industry analysis, yet it does not say ‘optional reading.’ I’m sure this is testable material but is it worth time to read both thoroughly as opposed to relying on shortened review marteial? I’ve read Schweser and now going through select CFAI text and notice a lot of repetition, and points being reiterated very often. There’s value in repetition, but seems like a lot of text is redundant could be reduced by 50% is still impart the same material. Thanks, John

I wouldn’t spend much time on that…pretty common sense…except you just have to know the 5 forces
