Five financial variables are utilized as components, i.e. industry size, operating efficiency, liquidity, profitability, and financial leverage in this study. Six years data from 2008 to 2013 have been collected from Karachi Stock Exchange. The consequences of 29 cement industries showed that there is a huge relationship between industry size, operating efficiency, and profitability with 181 systematic risk and results similar to past studies while liquidity and financial leverage have not a significant relationship with beta （systematic risk）. Results are profitable for budgetary approach creators and investors to expand the profits.展开更多
