An investment firm is analyzing the performance of different stocks in their portfolio.

They have collected data on the daily returns of three stocks, A$,$ B$,$ and C$,$ over a period of

one month. The daily return data is represented by a matrix $R,$ where each element $r_{ij}$

represents the return of stock $i$ on day $j.$ The matrix $R$ is given by:

$\left[\begin{array}{cccc}0\mathrm{.}02& 0\mathrm{.}01& -0\mathrm{.}03& 0\mathrm{.}01\\ 0\mathrm{.}03& -0\mathrm{.}02& 0\mathrm{.}01& 0\mathrm{.}02\\ 0\mathrm{.}01& 0\mathrm{.}02& 0\mathrm{.}03& -0\mathrm{.}01\end{array}\right]$

Determine the average daily return for each stock.
