We study the investment behavior of foreign investors in association with an equity market liberalization, and find a strong link between foreigners' trading and local market returns. In the period following the liberalization, net purchases by foreign investors induced a permanent increase in stock prices, suggesting that local firms reduced their cost of equity capital. We also find a strong link between a firm's fraction of foreign ownership and the magnitude of the cost reduction. Foreign investors seem to prefer large and well-known firms, and these firms realize the largest reduction in capital cost. Furthermore, our analysis suggests that foreigners increase their net holding in firms that have recently performed well. Analyzing foreigners' performance, we find very little evidence of informed trading, suggesting that risk sharing is the most plausible explanation for the reduction of the cost of equity capital.
