AB  - US subprime crisis and the European sovereign debt crisis affected indiscriminately both the economic and the
financial sectors giving rise to a bank run which made the survival of many other banks uncertain, and by contagion
the equity markets tumbled. In this context, this study runs a Data Envelopment Analysis model to analyse individual
market return and net sales in light of the interest income, depreciation, cost of goods and employees. Using data
from the largest companies of the Portuguese index stock market, the results showed that energy, communications
and banking are the sectors more prevalent regarding revenue efficiency.
