Abstract

Capital controls can induce large and persistent deviations from the Law of One Price for cross-listed stocks in international capital markets. A considerable literature has explored firm-specific factors which influence ADR pricing when LOP is violated. In this paper, we examine the interlinkages between Indian ADR premiums and macro economic time-series. We construct an ADR premium index, whereby diversification across firms diminishes idiosyncratic fluctuations associated with each security. We find that the S&P 500 index and the domestic Nifty index influence the ADR Premium Index. Positive shocks to the ADR premium index precede higher purchases by foreign investors on the domestic market, and precede positive returns on the domestic index.
