Q-87. A risk manager gathers five years of historical returns to calculate the Spearman rank correlation coefficient for stocks X and Y. The stock returns for X and Y from 2010 to 2014 are as follows:

| Year | X | Y |

Note: This question appears to be incomplete in the provided text. The table for Q-87 only shows the headers but not the actual return data for stocks X and Y. Therefore, I cannot calculate the Spearman rank correlation coefficient.
