Are options redundant? Further evidence from currency futures markets

This paper investigates the impact of the introduction of options on the underlying asset's price formation process, using Geweke feedback measures. We derive the feedback measures from the Deutsche Mark, British Pound, Swiss Franc, Japanese Yen and Canadian Dollar futures and spot prices, before and after the introduction of options for these currency futures. While each currency market maintains some distinct characteristics in the post-option period, a common theme is found: after the option introduction, the instantaneous feedback between spot and futures markets improves drastically. The feedback from the spot to the futures market tends to decrease and remains small. The feedback from the futures market to the spot market tends to decrease as well. These results confirm the dominance of options markets, probably due to their smaller transaction costs. When made available, options assume a leading role for information transmission in currency markets.     

THE EFFECT OF CROSS‐LISTING ON TRADING VOLUME: REDUCING SEGMENTATION VERSUS SIGNALING INVESTOR PROTECTION

We examine the relation between cross‐listing on the U.S. and UK regulated and unregulated exchanges and trading volume for a sample of 500 foreign firms from 34 countries. We find that the increase in trading volume is a function of both reducing segmentation and signaling investor protection. In addition, we find that home market trading volume, firm size, firm returns, and analyst forecast accuracy are the major determinants of a firm's trading volume. We also show that U.S. and UK investors trade foreign securities that originate from low‐investor‐protection countries more than they trade those from high‐investor‐protection countries, which is consistent with the bonding hypothesis.     

Identifying the interaction between stock market returns and trading flows of investor types: Looking into the day using daily data

This paper introduces a new method for identifying the simultaneity between returns and trading flows. The proposed method enables us to identify the intraday interaction using daily data, and provides measures of the information content of trading flows, and their instantaneous response to public information and information revealed by market prices. Applying this method to daily data on investor types from the Korea Stock Exchange, we find significant intraday bi-directional interaction between flows and returns and their latent common drivers, altering some of the results of the previous literature based on Cholesky assumptions. Thus, we obtain a number of new insights concerning the behavior of investor types.     

The ADR shadow exchange rate as an early warning indicator for currency crises

We develop an indicator for currency crisis risk using price spreads between American Depositary Receipts (ADRs) and their underlyings. This risk measure represents the mean exchange rate ADR investors expect after a potential currency crisis or realignment. It makes crisis prediction possible on a daily basis as depreciation expectations are reflected in ADR market prices. Using daily data, we analyze the impact of several risk drivers related to standard currency crisis theories and find that ADR investors perceive higher currency crisis risk when export commodity prices fall, trading partners’ currencies depreciate, sovereign yield spreads increase, or interest rate spreads widen.     

Portfolio optimization in the presence of dependent financial returns with long memory: A copula based approach

In this paper, we seek to examine the effect of the presence of long memory on the dependence structure between financial returns and on portfolio optimization. First, we focus on the dependence structure using copulas. To select the best copula, in addition to the goodness of fit tests, we employ a graphical method based on visual comparison of the fitted copula density and the smoothed copula density estimated by wavelets. Moreover, we check the stability of the copula parameter. The empirical results show that the long memory affects the dependence structure. Second, we analyze the impact of this dependence structure on the optimal portfolio. We propose a new approach based on minimizing the Conditional Value at Risk and assuming that the dependence structure is modeled by the copula parameter. The empirical results show that our approach outperforms the traditional minimizing variance approach, where the dependence structure is represented by the linear correlation coefficient.     

Overreaction of country ETFs to US market returns: Intraday vs. daily horizons and the role of synchronized trading

In this paper we study the intraday price formation process of country Exchange Traded Funds (ETFs). We identify specific parts of the US trading day during which Net Asset Values (NAVs), currency rates, premiums and discounts, and the S&P 500 index have special effects on ETF prices, and characterize a special intraday and overnight updating structure between these variables and country ETF prices. Our findings suggest a structural difference between synchronized and non-synchronized trading hours. While during synchronized trading hours ETF prices are mostly driven by their NAV returns, during non-synchronized trading hours the S&P 500 index has a dominant effect. This effect also exceeds the one that the S&P 500 index has on the underlying foreign indices and suggests an overreaction to US market returns when foreign markets are closed.     

The Information Content Of Calls Of Debt: Evidence From Long-Run Stock Returns

We examine the long‐run performance of the common stock of firms following calls of both straight and convertible debt from 1945 to 1995. Using a sample of 718 calls of straight debt, we find an average abnormal return in the five years following the call of between 0.16% and 0.34% per month, which compounds to an economically and statistically significant 11% to 22% over the five‐year period. This evidence of overperformance following calls shows a distinct symmetry between the straight debt and equity markets. Issues of debt and equity are both followed by long‐term underperformance, whereas stock repurchases and debt calls are both followed by long‐run overperformance. For our sample of 713 calls of convertible debt, we find little systematic evidence of abnormal performance following the call. Some researchers suggest that calls of convertible debt provide negative signals to the market. Our results provide no support for this claim. In contrast, our evidence of marginal positive long‐run returns provides weak support for the model that calls of convertible debt signal the realization of profitable investment options, and for the price pressure hypothesis.     

Why do companies delist voluntarily from the stock market?

We analyse the motives and market valuation of voluntarily delisting from the London Stock Exchange. We show that firms that delist voluntarily are likely to have come to the market to rebalance their leverage rather than to finance their growth opportunities. During their quotation life, their leverage and insider ownership remained very high, they did not raise equity capital, and their profitability, growth opportunities, and trading volume declined substantially. They also generate negative pre-event and announcement date excess returns. These results hold even after controlling for agency, asymmetric information, and liquidity effects, and suggest that firms delist voluntarily when they fail to benefit from listing. Overall, these firms destroyed shareholder value and they should not have come to the market.     

Information content of IPO grading

In the year 2007, Indian capital market regulator-SEBI, introduced a unique certification mechanism for IPOs whereby all IPOs have to undergo mandatory quality grading by independent rating agencies. In this paper we argue that such objective, independent and exogenous certifying mechanism provides a better opportunity to test the well established certification hypothesis, especially in the context of emerging markets with institutional voids. Using a sample of 163 Indian IPOs we test the efficacy of IPO grading mechanism. We find, grading decreases IPO underpricing and positively influences demand of retail investors. Grading reduces secondary market risk and improves liquidity. However, grading does not affect long run performance of the IPOs. IPO grading successfully capture firm size, business group affiliation and firm’s quality of corporate governance. Our findings imply that, in emerging markets, regulator’s role to signal the quality of an IPO contributes towards the market welfare.     

Board composition and operational risk events of financial institutions

We investigate the relation between board composition and operational risk events of financial institutions in the period from 1996 to 2010. Drawing from corporate governance literature, we consider the impact of board characteristics on the likelihood of operational risk events. Overall, our findings suggest that board size is negatively and non-linearly associated with the possibility of operational risk events. For the event types of “Clients, Products, and Business Practices,” and “Internal Fraud and External Fraud,” firms with a higher proportion of independent directors are less likely to suffer from fraud or failure to comply with professional obligations to clients. Our results on age and tenure heterogeneity also indicate that having a more diverse board can have an adverse impact on the board monitoring function. These results can shed new light on board demographics and operational risk management in financial institutions.     

Bias in estimating the systematic risk of extreme performers: Implications for financial analysis, the leverage effect, and long-run reversals

We show how bias can arise systematically in the beta estimates of extreme performers when long-run return reversals are present and partly, or wholly, due to sign changes in unanticipated factor realizations. Our evidence is consistent with this bias being responsible for the large shifts in the beta estimates of extreme performers, more so than the leverage effect, which has been the predominant explanation in prior literature. Bias in these contemporaneous realized betas, estimated with the same returns that are to be risk adjusted, arises due to the general problem of “overconditioning,” where betas are estimated conditional on information that is not yet known. Several methods for conditioning betas on out-of-sample returns are evaluated and found to be lacking, although some offer improvement under certain circumstances. We also show evidence of this bias in the Fama-French Three-factor loadings of extreme performers. Our findings indicate not only that previous studies of long-run reversals understate contrarian profits but that bias is prevalent in the OLS beta estimates of extreme performers, and this has implications for estimating the cost of capital and measuring long-run performance. We offer recommendations for identifying when this bias is likely present, as well as general methods to correct for it.     

Frequent issuers’ influence on long-run post-issuance returns

Prior studies conclude that firms’ equity underperforms following many individual sorts of external financing. These conclusions naturally raise significant questions about market efficiency and/or about the techniques used to measure long-run “abnormal returns.” Rather than concentrating on a single security type or issuance, we examine long-run performance following any and all sorts of security issuances. Initial financing events do not associate with underperformance; however, subsequent financings do. Our results suggest that negative post-issuance returns have nothing to do with the specific type of security issued, and everything to do with the number of types of securities issued.     

THE ENDOGENEITY OF INFORMATION ASYMMETRY AND CORPORATE FINANCING DECISIONS

Firms endogenize the extent of information asymmetry by choosing the optimal level and channels of direct communication with the capital markets. Firms choose more communication when they have a greater potential demand for external financing (characterized by higher growth, less cash, and higher leverage). We demonstrate that a higher level of communication is associated with a higher probability of equity issuance. We further document that the previously observed negative market reaction to seasoned equity offering (SEO) announcements is attributed only to low‐communication firms; high‐communication SEO firms experience no significant adverse market reaction.     

The role of time value in convertible bond call policy

Since the seminal work of Ingersoll (1977b) the optimal time in which a firm should redeem its outstanding convertible bonds has received large attention by the financial literature. Several studies have put forward a number of possible costs and benefits for a firm if it interrupts the life of its convertible bonds prior to their contractual maturity. However, in this paper we argue that the managerial decision to call back a convertible bond is mainly driven by a fundamental variable almost neglected up until now: the time value extraction from bondholders’ conversion option. Accordingly, we propose a measure for the effective convenience of calling—which we define as net time value advantage—and we show, using a survival analysis, that it is more effective than previously proposed measures in explaining the firms’ observed call policy.     

Conflicts of interest and China's A-share underpricing

The extremely high A-share underpricing in China's primary market provides us with a very interesting area of empirical research. Previous studies on China's IPO underpricing have been suggestive, but inconclusive. A significant decline in A-share underpricing is found in 2003 relative to previous years (and much less than that recorded in the literature to date). We examine the validity of previous A-share underpricing models, reported in the literature, and find a statistically significant structural break in the data during 2003 when these models are specified. We further explore conflicts of interest in the Chinese IPO market and specify an alternative model to further examine this change in observed market behavior. Our results suggest that a contract with high underwriter's fee leads to less A-share underpricing. Our results also suggest that the asymmetric information hypothesis does not apply in the Chinese IPO market in 2003. Overpricing by the secondary market and the trading activity on the first trading day are the main functions of the A-share underpricing. This study has important implications such as guiding the Chinese government policy regarding the regulations of initial public offering.     

Stock Returns and Operating Performance of Securities Issuers

We examine long‐run stock returns and operating performance around firms’ offerings of common stock, convertible debt, and straight debt from 1985 to 1990. We find that pre‐issue abnormal returns are positive and significant for stock issuers, but not for convertible and straight debt issuers. The post‐issue mean returns show that common stock and convertible debt issuers experience underperformance during the post‐issue periods, but straight debt issuers do not. Consistent with these results, common stock issuers experience the best pre‐issue operating performance among all three types of issuers, and operating performance declines during the post‐issue periods for common stock and convertible debt issuers. Using a new approach in linear model estimations to correct heteroskedasticity and to adjust for finite sample, we find a positive relation between post‐issue operating performance and issue‐period stock price reactions. The results suggest that future operating performance is anticipated at the issue and that securities issues provide information on issuers’ future performance.     

Are there windows of opportunity for convertible debt issuance? Evidence for Western Europe

This paper hypothesizes that hot convertible debt windows represent periods with lower convertible debt-related financing costs. Supporting this premise, we find that the stock price impact of Western European convertible debt announcements is significantly less negative during hot convertible debt windows. Importantly, this result holds while controlling for equity and straight debt issuance volumes and for macroeconomic conditions. In addition, stockholders are less sensitive to issuer- and issue-specific financing costs during hot convertible debt markets. Overall, these findings indicate that hot convertible debt markets represent windows of opportunity for convertible debt issuance. Firms with high idiosyncratic financing costs act accordingly by timing their convertible debt offering during a hot market.
