Cross-sectional and time-series momentum returns and market dynamics: evidence from Japan

We test the behavioural theories of overconfidence and underreaction on cross-sectional (CS) and time-series (TS) momentum returns in the Japanese stock markets. Both CS and TS momentum returns are large and significant when the market continues in the same state and turns into losses when the market transitions to another state, consistent with the overconfidence but not the underreaction model. We find that TS conditional momentum returns exceed conditional CS momentum returns because of its active position since TS takes a net long (short) position following UP (DN) markets while CS is a zero-cost strategy irrespective of the market state. Finally, we find no relation between idiosyncratic volatility (IV) and momentum returns which is not supportive of either the overconfidence or underreaction model but implies that IV is not a significant limit to arbitrage in Japan.     

Information in stock prices: the case of the 2016 U.S. presidential election

On the day before the 2016 U.S. presidential election, the odds of Hillary Clinton winning the presidency, according to political prediction markets, were above 90%. Surprisingly, Donald Trump won the Electoral College handily. In this study, we examine how movements in specific stock prices foreshadowed the eventual outcome. Specifically, we conduct a series of standard event-study tests focused on pharmaceutical companies, which became a focal point during the presidential campaign. Results show that while stocks of pharmaceutical companies significantly underperformed the market prior to the election, prices substantially increased beginning three days before the election outcome. This increase is both statistically significant and economically meaningful and robust to various event-study methodologies. These results suggest that some sectors of the stock market seemed to anticipate the election outcome.     

试论国内区际贸易与对外贸易利益的关系

对外贸易的发展理应建立在国内区际贸易充分开展的基础上。国内区际贸易的开展对对外贸易利益的取得具有重要的意义。我国改革开放过程中的国内市场分割现象,使得国内区际贸易滞后于对外贸易快速发展,并制约了对外贸易利益最大化的实现。本文的政策结论是通过加快改革逐步实现国内经济市场化和一体化以提高外贸利益。     

Pricing fx forwards in OTC markets – new evidence for the pricing mechanism when faced with counterparty risk

By using daily foreign exchange (fx) market data for five major currency pairs, this article shows that, especially since the beginning of the financial crisis, pricing of fx forwards has not matched the pricing formula derived from the covered interest rate parity (CIP). This corresponds to previous empirical results. Therefore, the CIP leads to systematic over- or underpricing. Overall, four statistically significant explanatory factors for this systematic over- or underpricing have been identified – the volatility in the difference between the interest rate levels, the spot price, the fx forward spread and the counterparty risk. In particular, the high significance of the counterparty risk demonstrates that pricing models for fx forwards should be reviewed.
