Quotes

[17:27] - "The majority of active managers underperform their benchmarks. So, that’s another key takeaway - don’t underestimate how difficult it is, and impossible systematically, to outguess market prices. [However], if you want to outperform markets, you don’t have to do that. You can seek to outperform markets by focusing on what you mentioned earlier. [Having an] evidence-based approach [and] premiums that are motivated by a robust [research]. ” ~ Savina Rizova

[22:57] - "The one thing many people misunderstand is: market efficiency is a model of how to think about the world or investing. Every model, by default, is wrong [and] is not an accurate description of reality. What is useful about models, is they help you organize how you think about [the world] and how you behave.” ~ Savina Rizova
