Pricing of American Depositary Receipts under Market Segmentation

This article examines the pricing of American Depositary Receipts (ADRs) in a three-factor pricing model. A seemingly unrelated regression model is utilized to test the nonlinear parameter restriction implied by the model. It is found that, although ADRs are traded in the U.S. securities market, their returns are significantly affected by their respective home market factors rather than by U.S. market movements. While U.S. investors are exposed to incremental risk from foreign equity market, they do not command a risk premium. The findings suggest that (1) markets are segmented and ADR listing does not integrate world capital market and (2) ADRs behave more like a foreign security and ADR is an effective tool of global risk diversification for U.S. investors.
