Investor attention,ETF returns,and country-specific factors

Using the data of 47 single-country exchange-traded funds (ETFs) traded in the U.S. from 36 countries during 2004–2017, this research examines the impact of investor attention proxied by Google Search Volume Index and home country-specific factors on different quantile of their returns. Evidence first shows that compared with U.S. investor attention, home country investor attention largely correlates with low to medium ETF returns, supporting the attention-induced price pressure hypothesis. Second, home country-specific factors significantly affect ETF returns at different conditional quantiles. We also find that investors prefer investing in a country with strong similarity to that of the U.S., supporting the cross-country information asymmetry hypothesis. Third, an intervening effect of home country-specific factors exists on the relationship between U.S. investor attention and ETF returns. These findings should help government authorities find appropriate strategies to attract foreign investment and upgrade the value of their capital market as well as provide a reference on efficiency for equity investors.

Emerging market exchange rates during quantitative tapering: The effect of US and domestic news

We analyze the impact of domestic and US-based news announcements of a large set of economic and policy-related fundamentals on the US dollar versus the Turkish lira exchange rate from 2013 to 2016. Since exchange rate behavior is closely related to political trust, we also incorporate the effect of domestic and global political uncertainty, using country indices based on Google search results. Contrary to previous findings, our results reveal that surprises related to the domestic economy have a greater effect on the exchange rate compared to surprises related to the US economy. Most important are the surprises related to domestic inflation and monetary policy, as well as foreign employment, while political uncertainty plays a minor role. There is also an asymmetry in the market response. Bad news about the US economy has more impact than good news, and good news about the domestic economy has more impact than bad news.
