Divergence of Opinion and Post-Acquisition Performance   总被引:1,自引:0,他引:1  
Abstract:  We examine the relation between divergence of opinion about the value of the acquiring firm in the pre-acquisition announcement period and post-acquisition stock returns. We find that acquirers subject to high opinion dispersion earn lower future returns than acquirers subject to low dispersion. It appears that, on average, only acquirers in the high divergence of opinion subset experience significant negative post-event abnormal returns. In the spirit of Miller (1977) , such evidence implies that high pre-event investor disagreement leads to systematic overpricing of acquirers that manifests itself through long-run underperformance of their stock. The documented misvaluation persists irrespective of the opinion divergence proxy and performance evaluation method used and after controlling for several common deal and acquirer characteristics.  相似文献

基于中文媒体构建的中国经济政策不确定性指数,研究经济政策不确定性对股价崩盘风险的影响效果和机制。结果显示:经济政策不确定性的提高会显著加剧股价崩盘风险,这表明经济政策不确定性是崩盘风险的诱因之一。通过对影响机制检验发现,经济政策不确定性对股价崩盘风险的正向作用,随着投资者意见分歧的增加而加强。在宏观经济良好时期,非国有股权和规模较大的企业,经济政策不确定性并未明显加剧股价崩盘风险,甚至起到了缓解股价崩盘风险的作用。  相似文献

Abstract:  We find that opinion divergence among professional investment managers is commonplace, using a large sample of transaction-level institutional trading data. When managers trade together, future returns are similar regardless if they are all buying or selling, inconsistent with the notion that professional investment managers possess stock picking ability or private information that is of investment value. However, when managers trade against each other, subsequent returns are low, especially for stocks that are difficult to short. This U-shaped disagreement-return relationship is consistent with Miller's (1977) hypothesis that, in the presence of short-sale constraints, opinion divergence can cause an upward bias in prices.  相似文献

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.  相似文献

The main purpose of this study is to analyze the association of financial reporting quality and investors' divergence of opinion. We focus on UK firms listed on the London Stock Exchange. Divergence of opinion is measured by two proxies based on unexpected trading volume and by dispersion in analysts' forecasts made one and two years ahead. Previous literature shows that the amount of firms' disclosure is negatively associated with the dispersion in analysts' forecasts. The results obtained in our study show that the quality of the disclosure is negatively associated with divergence of opinion, whether it is proxied by measures of unexpected trading volume or dispersion in analysts' forecasts. Financial reporting quality affects divergence of opinion not only in the months that immediately follow the disclosure of the reports but in the whole year that follows.  相似文献

Short sale constraints can inflate market prices, as bearish investors cannot act on their market views. The paper uses data from the Indian equity market to test whether opinion dispersion leads to higher overpricing when short sales are prohibited. The Indian equity market provides a natural testing environment, as short sales were banned between 2001 and 2008. The empirical results offer supportive evidence of the relation between opinion dispersion and overpricing in a market with short sale constraints.  相似文献

This paper demonstrates that the cross-sectional variation of liquidity commonality has increased over the period 1963–2005. The divergence of systematic liquidity can be explained by patterns in institutional ownership over the sample period. We document that our findings are associated with similar patterns in systematic risk. Our analysis also indicates that the ability to diversify systematic risk and aggregate liquidity shocks by holding large-cap stocks has declined. The evidence suggests that the fragility of the US equity market to unanticipated events has increased over the past few decades.  相似文献

This paper presents a new pattern in the cross-section of expected stock returns. Stocks tend to have relatively high (or low) returns every year in the same calendar month. We recognize the annual cross-sectional autocorrelation pattern documented in Jegadeesh [1990. Evidence of predictable behavior of security returns. Journal of Finance 45, 881–898] at lags of 12, 24, and 36 months as part of a general pattern that lasts up to 20 annual lags, superimposed on the general momentum/reversal patterns. This pattern explains an economically and statistically significant magnitude of the cross-sectional variation in average stock returns. Volume and volatility exhibit similar seasonal patterns but they do not explain the seasonality in returns. The pattern is independent of size, industry, earnings announcements, dividends, and fiscal year. The results are consistent with the existence of a persistent seasonal effect in stock returns.  相似文献

We examine the long-run common stock performance of preferred stock issuers. We find that significant abnormal underperformance is present only for 1 year after the issue. For the longer term we do not find consistently significant abnormal performance. This result contrasts with substantial underperformance of common equity and debt issuers during the 3 or 5 years post-issue. The better long-run performance of preferred issuers relative to common equity and debt issuers is driven primarily by financial firms' motivation to issue preferred stock to satisfy regulatory requirements of capital adequacy.  相似文献

The expectations hypothesis of the term structure has been decisively rejected in a large empirical literature that spans several decades. In this paper, using a newly constructed dataset of synthetic zero-coupon bond yields, we show that evidence against the expectations hypothesis is substantially weaker in data generated after the widespread publicity of its failure. These results are consistent with the idea that asset pricing anomalies tend to disappear once they are widely recognized.  相似文献

We develop a new methodology that controls for both the timing of annual earnings news (Asquith et al., 1989) and the performance prior to split announcements (Barber and Lyon, 1996) to evaluate the information content of stock splits. In contrast to existing evidence, we find that stock splits in aggregate are followed by positive abnormal future earnings growth, suggesting that stock splits contain information about future, rather than past, operating performance. When we use changes in breadth of institutional ownership as a new metric of information content to corroborate our findings, we find that splits with the greatest increase in breadth experience positive post-split abnormal returns and positive abnormal earnings growth. Together, our results suggest that some splits contain positive information about future performance, and that sophisticated market participants such as institutional investors are able to select these splits.  相似文献

Models of adverse selection risk generally assume that market makers offset expected losses to informed traders with expected gains from the uninformed. We recognize that the expected loss captures a combination of two effects: (1) the probability that some traders have private information, and (2) the likely magnitude of that information. We use a maximum-likelihood approach to separately estimate the probability and magnitude of private information events for NYSE-listed stocks from 1993 through 2003. The results shed light on the price discovery process and have implications for many areas of finance.  相似文献

We show that asset prices behave very differently on days when important macroeconomic news is scheduled for announcement. In addition to significantly higher average returns for risky assets on announcement days, return patterns are much easier to reconcile with standard asset pricing theories, both cross-sectionally and over time. On such days, stock market beta is strongly related to average returns. This positive relation holds for individual stocks, for various test portfolios, and even for bonds and currencies, suggesting that beta is after all an important measure of systematic risk. Furthermore, a robust risk–return trade-off exists on announcement days. Expected variance is positively related to future aggregated quarterly announcement day returns, but not to aggregated non-announcement day returns. We explore the implications of our findings in the context of various asset pricing models.  相似文献

This paper identifies observable firm-specific attributes that drive momentum. We find that a firm's revenues, costs, and growth options combine to determine the dynamics of its return autocorrelation. We use these insights to implement momentum strategies (buying winners and selling losers) with both numerically simulated returns and CRSP/Compustat data. In both sets of data, momentum strategies that use firms with high revenue growth volatility, low costs, or valuable growth options outperform traditional momentum strategies by approximately 5% per year.  相似文献

There is a large body of literature examining the association between stock characteristics and the cross-section of stock returns in international markets. Recently, Cooper et al. (2008) reported a strong association between total asset growth and stock returns in the US. In this paper, we show that an asset-growth effect also exists in the Australian equity market. Of particular interest, it is present amongst the largest Australian stocks. Over the 1983-2007 period, an equally-weighted portfolio of low-growth Big stocks outperforms a portfolio of high-growth Big stocks by an average 1% per month, equating to nearly 13% per annum. At an individual stock level of analysis, the asset-growth effect remains even after controlling for other variables whose association with the cross-section of returns is well known. Finally, we explicitly test whether asset growth is a priced risk factor using the common two-stage cross-sectional regression methodology. We find no evidence to support a risk-based explanation, thereby lending credence to Cooper et al.’s (2008) suggestion that the asset-growth effect is attributable to mispricing.  相似文献

This paper investigates the components of liquidity risk that are important for understanding asset-pricing anomalies. Firm-level liquidity is decomposed into variable and fixed price effects and estimated using intraday data for the period 1983–2001. Unexpected systematic (market-wide) variations of the variable component rather than the fixed component of liquidity are shown to be priced within the context of momentum and post-earnings-announcement drift (PEAD) portfolio returns. As the variable component is typically associated with private information [e.g., Kyle, 1985. Econometrica 53, 1315–1335], the results suggest that a substantial part of momentum and PEAD returns can be viewed as compensation for the unexpected variations in the aggregate ratio of informed traders to noise traders.  相似文献

Behavioral theories predict that firm valuation dispersion in the cross-section (“dispersion”) measures aggregate overpricing caused by investor overconfidence and should be negatively related to expected aggregate returns. This paper develops and tests these hypotheses. Consistent with the model predictions, I find that measures of dispersion are positively related to aggregate valuations, trading volume, idiosyncratic volatility, past market returns, and current and future investor sentiment indexes. Dispersion is a strong negative predictor of subsequent short- and long-term market excess returns. Market beta is positively related to stock returns when the beginning-of-period dispersion is low and this relationship reverses when initial dispersion is high. A simple forecast model based on dispersion significantly outperforms a naive model based on historical equity premium in out-of-sample tests and the predictability is stronger in economic downturns.  相似文献

We estimate buy- and sell-order illiquidity measures (lambdas) for a comprehensive sample of NYSE stocks. We show that sell-order liquidity is priced more strongly than buy-order liquidity in the cross-section of equity returns. Indeed, our analysis indicates that the liquidity premium in equities emanates predominantly from the sell-order side. We also find that the average difference between sell and buy lambdas is generally positive throughout our sample period. Both buy and sell lambdas are significantly positively correlated with measures of funding liquidity such as the TED spread as well option implied volatility.  相似文献

Are the returns of Chinese American Depositary Receipts (ADR) more affected by the US market or their underlying home market? We separate Chinese ADR daily returns into day and night returns to investigate the different market effects on ADR pricing. We compare “homeless” ADRs to home-based or cross-listed ADRs to see if they are affected differently by market factors. We find the night returns of Chinese ADRs are significantly affected by their home market (either the Hong Kong market or mainland China market) daily returns and the US market night returns. The US day returns appear to be the most significant pricing factor for the day returns of Chinese ADRs. The homeless ADRs are more affected by the US market and less affected by their home market compared to the cross-listed ADRs.  相似文献

This study investigates the convergence process toward efficiency of daily top gainers. The convergence process toward efficiency is much clearer as a result of using a GARCH(1, 1) model compared to the OLS model, and exhibits a monotonic decline as the time interval increases. The relationship between volatility and order imbalances is, however, not strong enough, suggesting that market makers do have the capability to reduce price volatility. This study develops an imbalance-based trading strategy, which earns a positive profit but fails to outperform the buy-and-hold strategy (i.e., open-to-close returns). A nested causality approach, which examines the dynamic return–order imbalance relationship during the price-formation process, confirms the results.  相似文献
