IMO , there wont be a standalone vignette on any single reading but CFAI will thread together all the concepts in a vignette , so its quite important to know almost all of it and each reading is different in its own way , such as MM theory , CAL , CML , active risk , use of treynor - black model ( a seminal contribution) and definitely on Int’ asset pricing , FCRP and differences between CAPM and ICAPM and dont miss the differences between multifactor models , APT which draws the concepts from multiple regression in quant .
Even though the readings are quite esoteric , I think apart from understanding the nuances one would be better off interpretting the concepts and trying to search anwers for these questions
what is the concept trying to convey ?
What are differences in the models used ? and why ? for ex : APT and CAPM , Treynor black model , FCRP and interest rate parity ( same as the one in economics)
Purpose of the models or practical applicability - for ex : active risk and benchmark portfolios .
All the best
