Adequate Information:
Markets are efficient.
To construct:
What should be the correlation coefficient between stock returns for two no overlapping time periods.
Introduction:Correlation Coefficientis a measure of strength of relationship between the relative movements of two variables.
Answer to Problem 1PS
Hence, the correlation coefficient for two non-overlapping periods shall be zero.
Explanation of Solution
In
If markets are efficient, then stock prices would always reflect any market information in their price movements at any point of time. The correlation coefficient for two non-overlapping periods shall be zero. Else, one may leverage returns from one period to
