Crossing the Lines: The Conditional Relation between Exchange Rate Exposure and Stock Returns in Emerging and Developed Markets

Abstract: This paper examines the importance of exchange rate risk in the return generating process for a large sample of non-financial firms from 37 countries. We argue that the effect of exchange rate exposure on stock returns should be conditional and show evidence of a significant return premium to firm-level currency exposures when conditioning on the exchange rate change. The return premium is directly related to the size and sign of the subsequent exchange rate change, suggesting fluctuations in exchange rates themselves as a source of time-variation in currency risk premia. For the entire sample the return premium ranges from 1.2 - 3.3% per unit of currency exposure. The premium is larger for firms in emerging markets, while in developed markets it is statistically significant only for local currency depreciations. Overall, the results indicate that exchange rate exposure plays an important role in generating cross-sectional return variation. Moreover, we show that the impact of exchange rate risk on stock returns is predominantly a cash flow effect as opposed to a discount rate effect.

What Lies Beneath: Foreign Exchange Rate Exposure, Hedging and Cash Flows

Abstract: This paper presents results from an in-depth analysis of the foreign exchange rate exposure of a large nonfinancial firm based on proprietary internal data including cash flows, derivatives and foreign currency debt, as well as external capital market data. While the operations of the multinational firm have significant exposure to foreign exchange rate risk due to foreign currency-based activities and international competition, corporate hedging mitigates this gross exposure. The analysis illustrates that the insignificance of foreign exchange rate exposures of comprehensive performance measures such as total cash flow can be explained by hedging at the firm level. Thus, the residual net exposure is economically and statistically small, even if the operating cash flows of the firm are significantly exposed to exchange rate risk. The results of the paper suggest that managers of nonfinancial firms with operations exposed to foreign exchange rate risk take savvy actions to reduce exposure to a level too low to allow its detection empirically.

Does adverse selection affect bid-ask spreads for options?

Abstract: This study examines two different option markets to test whether differences in the level of adverse selection faced by market makers affect the size of bid–ask spreads. The data are from bank-issued options that trade on EuWax, where market makers face little adverse selection and traditional options that trade on EuRex. The results support the hypothesis that the adverse selection component of the bid–ask spread is important, as options on EuWax have lower bid–ask spreads than comparable options on EuRex. The results show that the adverse selection component represents at least half of the overall bid–ask spreads on the traditional EuRex.

The Effect of Corporate Break-ups on Information Asymmetry: A Market Microstructure Analysis

Abstract: This paper investigates the information environment during and after a corporate break-up utilizing direct measures of information asymmetry developed in the market microstructure literature. The analysis is based on all corporate break-ups in the United States in the period 1995-2005. The results document that information asymmetry declines significantly as a result of a break-up. However, this reduction takes place not at the time of its announcement or its completion, but after it has been fully consummated. At the same time, not all investors are equally affected, but informed investors who generate private information by skilled analysis of public information come to play a more important role compared to traditional corporate insiders. This might explain why financial advisors promote break-ups among their corporate clients, as they are likely beneficiaries. The positive stock-market reaction to break-up announcements is significantly related to reductions in insider-related information asymmetry, indicating that the advantage of skilled information analysts does not offset the overall improvement in the information environment due to a break-up.

Are Short-sellers Different?

Abstract: While theoretical models strongly suggest that short-sales are mainly driven by private information, recent empirical evidence of has been rather mixed. This paper contributes to the discussion by looking at various potential motives to sell short and compares these with regular buys and sales with regards to variation in the information contents and timing of short-sales. We find that short-sellers have different private information than regular buyers and sellers, which seems to have a longer life-time, being related to previous buying pressure. The information advantage of short-sellers seems originating from skilled analysis of publicly available data rather than corporate insider information. Short-sales provide an important stabilizing role by providing liquidity in periods of uninformed buying pressure. Overall, we find that short-sales are driven by multiple trade motives, which sets short-sellers apart from regular buyers and sellers.
