Capital account reform and short- and long-run stock price leadership

This paper studies the effect of capital account liberalization policies on the price discovery of cross-listings in Chinese stocks. We construct a non-linear causality framework that decomposes short- and long-run dimensions of price leadership. Our analysis shows that capital account liberalization has had a profound effect on long-run A- and H-price leadership traits. Specifically, increased inward capital movement from Qualified Foreign Institutional Investors strengthens long-term leadership in the mainland A-market. Similarly, increased capital outflow from the Chinese mainland galvanizes long-term price discovery processes in the Hong Kong H-market. We thus offer strong evidence that capital account liberalization promotes stock market efficiency in the long-run. The present study's empirical account also suggests that such capital flows inhibit short-term lead-lag effects.     

Underwriting Relationships and Analyst Independence in Europe

This paper examines the accuracy of security analysts’ earnings forecasts and stock recommendations for firms in 13 European countries. We document at least three key findings. First, we find strong evidence that lead and co‐lead underwriter analysts’ earnings estimates and stock recommendations are significantly more optimistic than those provided by unaffiliated analysts. Second, we find that lead and co‐lead underwriter analysts’ earnings forecast and stock recommendations are significantly more optimistic for underwriter stocks than for those they provide for other stocks. Third, we also find evidence that these biases found within earnings forecasts and stock recommendations are not driven by one particular country. In short, these findings suggest that affiliated analysts are more optimistic perhaps to maintain investment banking relations.     

Economic uncertainty: Mispricing and ambiguity premium

We uncover two channels of effect in the financial market when investors face macroeconomic uncertainty. Conditional on a common mispricing index, we find that economic uncertainty exposure (EUE) induces disagreement, which amplifies mispricing. The highest EUE quintile produces an annualised mispricing alpha of 9.96%, more than double the unconditional mispricing effect. An ambiguity premium of 3.84% alpha is documented in the “non-mispricing” quintile. The EUE-induced mispricing effect is different from the existing limits of arbitrage explanations. The ambiguity premium is predictably observed during the unfolding of shocks of COVID-19 to the market.
