MPT AND CAPM Flashcards
what is Efficient frontier
what is the portfolio risk formula
what is mean and variance in portfolio risk
mean- return
variance- risk
in mpt the correlation should be +1 or -1
-1 but its not possible but it should be less than 1 so that MPT is diversified
if the correlation is +1 the risk of portfoli is ?
then the risk of portfolio is at the highest measured by weight a sq* variance a + weight b sq* variance b
if the correlation is -1 then the risk of portfolio?
the the risk of portfolio is at minimum measured by weight a square * variance a - weight b sq* variance b
assumption of mpt?
What global minimum variance in portfolio
global minimum variance is a point where the return is high and risk is less than the inefficient frontier
what happen after the efficient frontier? is there any portfolio there?
the portions beyond efficient frontier is unattainable and we should not invest in that
explain everything related to correlation in mpt
correlation should be -1 or less than 1 because that way the portfolio is diversified and if the assest 1 is going down then the asset 2 return can minimise the loss… but if its 1 then the movement are together is asset 1 is going down then asset 2 will also go down which is not desirable
in mpt who are rational investors?
rational investors are those who want to increase their mean return and low their variance
in mpt the return are normally distributed which means?
means skewness is 0 and kurtosis is 3 and we only focus on mean and variance of the return. we want mean return high and variance low
what is role of covariance in mpt ?
covariance (a,b) = correlation * sd a * sd b and if the correlation is less than 1 then i am happy
what is role of covariance in mpt ?
covariance (a,b) = correlation * sd a * sd b and if the correlation is less than 1 then i am happy
can correlation be 0 in mpt?
yes, if the correlation is 0 then the asset a and b are not correlated and we calculate risk of of the portfolio on the basis of weight and variance
why do we need New theory other than mpt ?
because mpt only involves risky asssets and no risk free asset
what is theory behind ic curve and utility in mpt?
