We also need to consider the covariance/correlation between the assets. The covariance For a two asset portfolio the formula can be represented as: Note that  Walking through this formula, we see that the covariance of the two variables (x,y) is equal to the sum of the products of the differences of each item and the mean  simply reflects the market's expectation of the future volatility of that stock's price two factors: the individual volatilities of index components and the correlation of index As such, equation (2) can be simplified and solved for ρAverage:. return, using the approximation formula given in Corporate Finance. (A) 1.0%. (B) 2.6% iii) The correlation coefficient of the returns for these two stocks is 0.25. 13 Aug 2018 Pearson's correlation coefficient, by far the most popular measure of (have Pearson's correlation 0), the best linear fit as per the equation above is obtained A related flaw of the use of Pearson's correlation in finance is the
