HOW CAN I COMPEAR BANK PERFORMANCE WITH INDEX MARKET

Answer 1

The question is not clear. so answering two possibilities.

1) bank performance VS index performance

there are many ways to do this one such way is to find the sharpe ratio for the bank average return and the index average return and compare them.

shape ratio = (return of portfolio - risk free rate) / standard deviation of the portfolio. higher the sharpe ratio, the better is the portfolio.

2) how bank performed for the market movements

for this case, we can go a regression analysis to bring out the linear equation keeping bank returns as the independent variable and index returns as the dependent variable.

from which we can get the beta of the bank and the alpha can be calculated.(jensen's alpha) by calculating the expected returns.
