Good job. Now if corr(A,B) is between -1 and 0, where would the portfolio P statistics fall with respect to the efficient frontier. Would it be in the triangle but still to the left of the frontier. min 5:26)

Thanks for the great video! One question: 7:34 your sigma P squared formula only applies situation that N asset has same volatility and all same pair Cov. why?

Thanks for the video, very helpful. Are correlation and covariance interchangeable in the portfolio risk equation for 2 assets? I am confused at how the equation is simplified when there is a perfect positive correlation.
@fincampuslecturehall48336 жыл бұрын
I wouldn't say they are interchangeable but are certainly related. It's just algebra. Substitute covariance with the correlation times weights that I have given, then use the fact that (a+b)^2 = a^2 + b^2 + 2ab. See if that gets you somewhere...

great video, can we get any reference for everything explained?
@peters9722 жыл бұрын
An assumption for this to work is that the stdev of past history of the asset will remain similar during the future position, so take care. And for the portfolio, things that seem un-correlated now may become ever so correlated in the future. Have a firm understanding of what the math is telling you, and what it is not.

Worst part of this theory is that it flat out assumes that asset returns are gaussian. Taleb has shown that much of modern finance theories are just piece of garbage.

Hi when the correlation is equal to 1, how do you eliminate the 2AB(VOLaVOLb) part to get the final portfolio volatity

Hi. Is there a derivation of this formula that is used to calculate the vol. of the portfolio. That is how do we know that the variance is an underroot of all that?
@fincampuslecturehall48337 жыл бұрын
Hi Priyanshu, "variance" is NOT an underroot of all that. In fact, by definition, volatility is the square root of variance. In this video, I am just going by the standard definition of variance of a portfolio with 2 assets. Forget portfolio theory for a second and try to compute the following (a+b)^2. Then try to compute (xa+yb)^2. See if you can figure out a pattern.

@fincampuslecturehall48337 жыл бұрын
Think of a universe of financial assets. You choose few of those assets and put them together in a portfolio such that there is no way to increase return without increasing risk or reduce risk without reducing return. That should be your starting point. With that, I would suggest you to watch the video again and let me know if you still have questions. Thanks
