6:10 Words to know: standard deviation (can also be thought of as "volatility"), variance, correlation (perfect correlation is 1, perfect inverse is -1), covariance 9:50 A correlation of 1 is not a well-diversified portfolio 14:36 John Burr Williams: Theory of Investment Value (1938) 17:30 The variance of the portfolio depends on not only the variances/volatility of the holdings, but also on how correlated they are 19:45 Leavens: "Diversification of Planning" (1945) 20:54 Markowitz: "Portfolio Selection" (1952) Roy: "Safety First and the Holding of Assets" (1952) 24:20 Portfolio theory is about risk-return tradeoff (it doesn't guarantee high return with low risk)
I had Harry markowitz in a PhD class at baruch college. In my opinon, he was a terrible teacher. NOthing that he taught worked1! He like most of the doctorial teachers at barauch read articles in academic journals then monkey see monkey do, try teaching the theory in these articles. PHD courses were all home made courses from research journals, not text books. You do not use text books in PHD courses, because you already know everything in the text books. College teachers usually try to LEARN theory from academic journals( articles) then try Teaching that theory in a course.!! Markowitz tried to teach a course on stochastic models, using set theory(borel sets). He NEVER got to stochastic calculus or markov models or anyting practical. This uas just academic garbage. I would actually write c++ programs to implement what he tried to teach, NOTHING WORKED. He finally gave up and told me "just stick with my traditional stuff, when your working "
