This article provides evidence of information transmission from the United States and Japan to Korean and Thai equity markets. Information is defined as important macroeconomic announcements in the United States, Japan, Korea, and Thailand. Using high-frequency intraday data, I find a large and significant association between developed-economy macroeconomic announcements and emerging-economy equity volatility and trading volume at short time horizons. Previous studies’ findings of at most weak evidence of transmission from developed to emerging economies may be due to their use of lower frequency data and their focus on developed-economy financial market innovations as a proxy for information.

International fund investment in bonds and equities is characterized by a positive association between current net inflows and contemporaneous and past market returns: positive-feedback trading, while being possibly profitable for international fund investors, could be destabilizing for the underlying markets. Allowing for interactions between equity investment and bond investment, our panel vector autoregression shows that past equity returns contain useful information in forecasting equity and bond flows and that bond flows impact future equity returns positively.

Counter to extant stylized facts, using newly available data on country allocations in US investors' foreign equity portfolios we find that (i) US investors do not exhibit returns-chasing behavior, but, consistent with partial portfolio rebalancing, tend to sell past winners; and (ii) US investors increase portfolio weights on a country's equity market just prior to its strong performance, behavior inconsistent with an informational disadvantage. Over the past two decades, US investors' foreign equity portfolios outperformed a value-weighted foreign benchmark by 160 basis points per year. JEL: C58, G11, G15
