Price reversals versus price continuations: the transitory price effects of futures trading extension on the underlying stock market

This paper examines the transitory price effects of index futures trading extension on the underlying stock market. Based on the model formulation of George and Hwang (1995) and Amihud and Mendelson (1987) and using the Hong Kong data, we find that the extension of futures trading hour helps to reduce the opening pricing errors and change the correlations between daytime and overnight stock returns. Our finding adds to the literature that the trading behavior of derivatives has a significant influence on the transitory price changes of the underlying cash products.

Transaction Costs and Price Volatility: New Evidence from the Tokyo Stock Exchange

We investigate the volatility impacts of the full commission deregulation in Japan in October 1999, and find that the deregulation overall tends to significantly increase price volatility in the Japanese equity market, using alternative model specifications and control variables. This finding contrasts with previous evidence that implies a positive relation between transaction costs and price volatility, while consistent from the converse with the hypothesis proposed by Stiglitz (1989) and Summers and Summers (1989). Our results suggest that imposing higher transaction costs might still be a feasible policy tool for stabilizing the market by curbing short-term noise trading.

Do German security analysts herd?

We employ an innovative methodology suggested by Bernhardt et al. (J. Financ. Econ. 80:657–675, 2006) to examine the herding (or anti-herding) behavior of German analysts regarding earnings forecasts. This methodology avoids well-known shortcomings often encountered in related studies, such as correlated information signals, unexpected common shocks to earnings, systematic optimism or pessimism, or forecast target mismeasurement. Our findings suggest that German analysts anti-herd, that is, they systematically issue earnings forecasts that are further away from the consensus forecast than their private information indicates. Furthermore, we analyze the association between herding behavior and different characteristics, including the size of the brokerage, general or firm-specific experience, and the coverage of firms on the Neuer Markt. We mainly confirm findings for the United States, for example, that anti-herding is more severe in cases of higher competition among analysts. Contrary to anecdotal evidence, we also find anti-herding behavior in earnings forecasts for Neuer Markt firms during the “new economy” bubble.

Price–volume relations of DAX companies

This study provides empirical evidence of the joint dynamics between stock returns and trading volume using stock data of DAX companies. Contemporaneous as well as dynamic interactions are investigated for a period from January 1994 to December 2005 on a daily basis. Our results suggest that there is almost no relationship between stock return levels and trading volume in either direction. We find that trading volume is contemporaneously positively related to return volatility. In addition, we establish that lagged return volatility induces trading volume movements. Finally, we examine dependencies in the tails and find no significant support for the hypothesis of the independence of the maximal values of absolute returns and trading volume.

Firm diversification and earnings management: evidence from seasoned equity offerings

Popular press suggests that diversified firms are more aggressive in managing earnings than non-diversified firms. We examine this claim in the seasoned equity offering (SEO) setting, where firms have been shown to have the incentive to manage earnings upwards. Using the cross-sectional modified Jones [(1991) J Accounting Res 29:193–228] model to measure discretionary current accruals, we find that discretionary current accruals are higher among diversified firms than in non-diversified ones. Our evidence is consistent with the view that the extent of firm diversification is directly related to the degree of earnings management. We further show that diversified issuers with high discretionary accruals underperformed other SEO firms.

The ex-dividend day stock price anomaly: evidence from the Greek stock market

This paper examines the ex-dividend stock price and trading volume behavior in the Greek stock market for the period 2000–2004. We use both standard event-study methodology and cross-sectional regression analysis in assessing the ex-dividend stock price anomaly. We find that stock prices drop less than the dividend amount. By examining abnormal returns as well as abnormal trading volume around the ex-dividend day, we find strong evidence of short-term trading, which is consistent with the presence of dividend-capturing activities around the ex-dividend day. The results from the cross-sectional regression analysis confirm that the short-term trading hypothesis explains the ex-dividend day stock price anomaly in Greece.

The relation between R&;D intensity and future market returns: does expensing versus capitalization matter?

The Australian accounting environment provides an ideal setting for examining the impact of different accounting treatments of firms’ R&D activities on their subsequent returns. Unlike US firms, which can only expense R&D, Australian GAAP permits firms to either expense or capitalize their R&D expenditure. We examine separately the market impact of the R&D intensity of all R&D active firms, ‘capitalizers’ and ‘expensers’. Our results suggest that firms with higher R&D intensity perform better, regardless of the accounting method used, consistent with the resource-based view of the firm. We also find some evidence that firms which expense R&D outperform those which capitalize R&D after controlling for R&D intensity.

Why do firms repurchase stock to acquire another firm?

This study investigates firms that repurchase their stock to finance an acquisition. Since research shows that cash-financed acquisitions perform better than stock-financed acquisitions, why do firms that have available cash initiate the extra transactional step. I find these firms are well compensated for their efforts, especially in the long run. On average, these firms have negative abnormal returns prior to their repurchase announcements and thus may choose repurchasing to signal undervaluation. Furthermore, the stock acquisition step allows these firms to share risk, counteract the negative effects of dilution, and enjoy a tax advantage for their efforts.

Mispricing and the cross-section of stock returns

This paper employs the Campbell-Shiller (Rev Financ Stud 1:195–228, 1988) VAR model to derive a model-based mispricing measure that captures investor overreaction to growth. Using this mispricing measure, we find that stocks with low levels of mispricing outperform otherwise similar stocks. The long–short mispricing strategy generates statistically and economically significant returns over the sample period of July 1981 to June 2006. Moreover, this mispricing strategy outperforms the contrarian strategy using various accounting-fundamental-to-price ratios. Our results cast doubt on the risk story in explaining the abnormal returns of the mispricing strategy. Rather, our evidence suggests that asset prices reflect both covariance risk and mispricing.

The Long-Horizon Performance of REIT Mergers

We study long-horizon shareholder returns in a comprehensive sample of Real Estate Investment Trust (REIT) mergers, to test whether or not the anomaly of post-merger underperformance observed in conventional firms applies to the case of REITs. Constructing synthetic benchmark portfolios controlling for firm size and for book-to-market value ratio, we find that 60-month buy-and-hold abnormal returns for REIT acquirers are significantly negative at approximately −10%, supporting the position that REIT merger acquirers underperform non-merging REITs in the long run. We find no evidence to challenge previous studies reporting positive announcement period returns for acquirers when the target is privately held, but we do find evidence that these positive returns do not persist. The long term performance of acquiring REITs is approximately the same whether the target is public or private.

The impact of H-share derivatives on the underlying equity market

We conjecture that an introduction of the Hong Kong Hang Seng Chinese Enterprise Stock Index (H-share Index) futures induces additional speculating activities in the underlying equities, leading to an increase in volatility and volume of the underlying stocks. Whereas, a subsequent introduction of H-share index options increases the level of informed trading and opens up opportunities for speculative and arbitrage activities using futures directly against options. These futures and options trading activities are much cheaper and more efficient than using the underlying stocks, leading to a significant decline in spot market volatility and volume. Our results are consistent with these arguments. We also find that derivative trading does not change the liquidity of H-share constituent stocks. Further tests based on the difference-in-difference approach confirm that the above findings are robust.

Implied measures of relative fund performance

We evaluate the relative performance of funds by conditioning their returns on the cross-section of portfolio characteristics across fund managers. Our implied procedure circumvents the need to specify benchmark returns or peer funds. Instead, fund-specific benchmarks for measuring selection and market timing ability are constructed. This technique is robust to herding as well as window dressing and mitigates survivorship bias. Empirically, the conditional information contained in portfolio weights defined by industry sectors, assets, and geographical regions is important to the assessment of fund management. For each set of portfolio characteristics, we identify funds with success at either selecting securities or timing-the-market.

Are the Fama–French factors proxying news related to GDP growth? The Australian evidence

Inspired by Vassalou (J Financ Econ 68:47–73, 2003), we investigate the contention that the Fama and French (J Financ Econ 33:3–56, 1993) model’s ability to explain the cross sectional variation in equity returns is because the Fama–French factors are proxying for risk associated with future GDP growth in the Australian equities market. To assess the validity of Vassalou’s findings, we augment the CAPM and the Fama–French model with a GDP growth factor and run system regressions of the GDP-enhanced models using the GMM approach. Our results suggest that news about future GDP growth is not priced in equity returns and that any ability that SMB and HML exhibit in explaining equity returns is not because they contain information about future GDP growth.

Specification analysis of corporate equity financing decision: a conditional residual approach

This article revisits the debate on the nature of private placements by specifying that informed insiders make trading decisions in the secondary market and equity issuance decision in the primary equity market (Lee and Wu (2008)). This article uses conditional residuals from the insider trading regression (abnormal insider trades) and conditional residuals from equity financing choice regression (unexpected equity financing choice) to measure private information. An important advantage of conditional correlation coefficient approach over the two-stage approach (Lee and Wu 2008) in testing the presence of asymmetric information is that the former is bounded by −1 and 1 and thus permits cross-sectional comparisons the relatedness between abnormal insider trades and unexpected equity financing choice.

Heterogeneous time varying transaction costs and asset pricing in international equity markets

In this paper, we examine the time variation in transaction costs relative to excess returns, in a panel consisting of 10 international equity indices over the time period 1984–2005. This is undertaken by extending the consumption CAPM (CCAPM) model proposed by Campbell and Shiller (Rev. Financ. Stud. 1:195–228, 1988) to incorporate time varying proportional transaction costs. We rigorously address both the cross-country heterogeneity in the estimated model and endogeneity. We find strong evidence that suggests transaction costs should be included as an additional explanatory variable in the CCAPM. This leads to the conclusion that transaction costs should be included in asset pricing models as their stochastic process impacts directly on private consumption expenditure.

Does acquirer cash level predict post-acquisition returns?

This paper investigates whether an acquirer’s pre-announcement cash level can predict post-acquisition returns. Harford (1999, Journal of Finance, 54, 1969–1997) shows that some cash-rich acquirers have lower announcement period returns than other acquirers, suggesting the market partially anticipates poor future performance. This paper shows that the acquirer’s cash level is also strongly and negatively predictive of post-acquisition returns, indicating that the announcement response is incomplete. Post-acquisition return on net operating assets (RNOA) is significantly decreasing in acquirer cash, suggesting that the market responds to subsequent poor operating performance as it is reported. Overall, these results are consistent with the market’s inattention to a less prominent accounting signal (acquirer cash) but attentiveness to a more prominent accounting signal (RNOA), as proposed by Hirshleifer and Teoh (2003, Journal of Accounting Economics, 36, 337–386).

Valuing corporate securities: some effects of bond indenture provisions—a correction

This paper identifies and corrects a typographical error in Black and Cox (J Finance 31:351–367, 1976). While the typographical error is seemingly trivial, the magnitude of the pricing error that it generates can be substantial.

Calendar Anomalies: The Case of International Property Shares

In this paper we analyze the price dynamics of international property shares for the ten most prominent markets from around the world plus South-Africa. We focus on the presence of calendar effects in daily and monthly price returns and examine these effects both over time and across countries. For the daily returns we find price anomalies for Fridays and Mondays in all markets. Friday returns tend to be the highest of the week, while Mondays are weakest. We find that these patterns were most prominent during the 1980s and early 1990s and in the smaller markets in our sample. For the monthly returns we found little evidence for price irregularities. In most cases January was superior to most other months, but these differences lacked statistical significance. More interesting was the sell in May effect that seemed to be present in ten out of 11 markets. Price returns during the winter season outperformed the summer months and in five countries these difference were both economically and statistically significant. Finally, we looked at firm level returns to isolate the drivers of these infamous calendar effects. The day-of-the-week effect appears to be most pronounced among small and young firms that have little or no institutional investors. Large and long-established listed real estate firms with a large portion of loyal block-holders experience no significant price patterns during the trading week.

The Reaction by Industry Insiders to M&;As in the European Financial Industry

This paper looks at the reaction by industry insiders, industry analysts and competing firms, to the announcement of M&As that took place in the European Union financial industry in the period 1998–2006. Analysts covering firms involved in an M&A transaction do not significantly alter their recommendation. This is consistent with the hypothesis that the transaction on average is “fairly priced” and that stock market prices reflect all relevant information on the assets. We also find that the correlation between excess returns for merging and competing firms is positive and, in some cases, significantly higher for domestic mergers than for international deals. This is consistent with the idea that domestic deals are more likely to have a negative impact on industry competition.

Takeover motives in a weak regulatory environment surrounding a market shock: a case study of New Zealand with a comparison of Gondhalekar and Bhagwat’s (2003) US findings

We examine the motives for takeovers in New Zealand surrounding the 1987 stock market crash and compare with the US findings of Gondhalekar and Bhagwat (2003). There are a number of structural differences between the New Zealand and US markets that could impact on merger motives. Compared with the US, New Zealand is a small capital market; with weak takeover regulation and a prolonged aftermath of the 1987 stock market crash. Consistent with US research, we find evidence of synergy and hubris motivations in New Zealand takeovers although we find the synergy motivation is stronger. Contrary to expectations we find no evidence of agency motivated takeovers.
