Revenue generation has a greater impact on long-term profitability and share prices than cost cutting alone. While cost cutting can provide short-term gains, investment banks should focus on innovating to create new business lines and revenue sources. An analysis of 12 banks found a strong correlation between operating revenue and pre-tax profit margins but a weak correlation with operating expenses. Revenue generation is thus a better determinant of valuation metrics like price-to-earnings and price-to-book value ratios.
