• Our study is the first to establish a significant negative relation between earnings transparency and cost of capital.
• Our transparency measure is based on the extent to which earnings and change in earnings covary with stock returns.
• Our transparency measure permits cross-sectional and intertemporal variation in the returns-earnings relation.
• Firms with more transparent earnings have lower cost of capital as reflected in subsequent excess and portfolio mean returns
• More transparent earnings also are significantly negatively associated with expected cost of capital.
We provide evidence that firms with more transparent earnings enjoy a lower cost of capital. We base our earnings transparency measure on the extent to which earnings and change in earnings covary contemporaneously with returns. We find a significant negative relation between our transparency measure and subsequent excess and portfolio mean returns, and expected cost of capital, even after controlling for previously documented determinants of cost of capital.
