Cleared up a lot of loose ends I guess. Starting to see how all this ties in/ blends in with the classic old-school vanilla CFA-style fundamental analysis. Not 2 different coins, but 2 sides of the same coin. Not gonna help me break into quant-ish strategies, but it certainly helps me understand at a high level these quant investing podcasts, newsletters and papers. Especially AQR, they seem heavy on factor investing and deep-diving into those factors so that's literally econometrics (some might take that as an insult to their genius quant skills, maybe). Classic Fama-French-ish factor modelling, that family of academic finance shit (as per the founders of AQR), honestly, can be dumbed down to a non-quant fairly easily. Don't want to get too ahead of myself here but getting kinda excited as I blend in these styles of investing, for my own interpretation.
Detailed, well-aranged, lots of examples and also exercises, well done. Still I am looking forward more to other parts as this one is basically maths and stats which is good, but not why I bought CFA books in the first place.
