In this paper, a capital asset pricing model (CAPM) incorporating liquidity and skewness factors is proposed and tested by using the Chinese stock market data. The empirical results indicate that, under various market conditions, the liquidity-adjusted three-moment CAPM provides a better fit to the realized returns of various stock portfolios. Overall, this research reveals that illiquidity cost, liquidity risk and as well as skewness have important impacts on asset pricing in the Chinese stock market.  相似文献

Liquidity and Liquidation: Evidence from Real Estate Investment Trusts   总被引:1,自引:0,他引:1  
This study provides evidence that highly leveraged owner-managed properties liquidated assets during the commercial real estate decline of the late 1980s, and that this provided buying opportunities for better capitalized buyers. The analysis documents significant financial distress costs for highly leveraged firms during an industry-wide downturn and shows that these costs are particularly large for owner-managed firms.  相似文献

How does increased noise trading affect market liquidity and trading costs? We use The Wall Street Journal's “Investment Dartboard” column, which stimulates noise trading, as a natural experiment to evaluate models of the bid-ask spread. We find that substantial increases in trading volume and significant but temporary abnormal returns occur when analysts recommend stocks in this column, especially when recommendations come from analysts with successful contest track records. We also find an increase in liquidity and a decrease in the adverse selection component of the bid-ask spread.  相似文献

We examine the impact of information asymmetry on a firm??s choice between cash and credit lines for corporate liquidity management using a panel data set from real estate investment trusts (REITs). Information asymmetry, as measured by analyst forecast error and dispersion, is negatively related to the use of lines of credit. Specifically, firms with more severe information asymmetry are less likely to have access to bank credit lines. Concurrently, more transparent firms are more likely to utilize bank credit lines as opposed to cash for liquidity management. The results are robust to alternative information asymmetry proxies and specifications. These findings suggest that information asymmetry plays an important role in corporate liquidity management.  相似文献

This study contrasts the call and continuous auction methods using Taiwan Stock Exchange data. Volatility under the call market method is approximately one-half of that under the continuous auction method. The call market method is more effective in reducing the volatility of high-volume stocks than low-volume stocks. This contradicts conventional wisdom which suggests that the call market method is superior for thinly traded stocks, while the continuous auction method is preferred for heavily traded stocks. The call market method does not impair liquidity and price discovery. The call market appears more efficient than in the continuous auction market.  相似文献

We use the EU stress tests and the Eurozone sovereign debt crisis to study the consequences of supervisory disclosure of banks’ sovereign risk exposures. We test the idea that a mandatory one‐time disclosure induces an increase in voluntary disclosures about sovereign risk in the following periods and, through the shift in the voluntary disclosure equilibrium, increases the liquidity of banks’ shares. First, we find that the timing and content of different mandatory disclosure events helps explain the levels of stress‐test banks’ voluntary disclosures about sovereign risk. Second, although the bid‐ask spreads of stress test participants generally increased after the mandatory stress test in 2011, our results suggest that the decrease in market liquidity is entirely attributable to those stress‐test participants that did not commit to voluntarily maintaining the disclosures of sovereign risk exposure.  相似文献

I examine the effect of demand on stock prices by analyzing the conversion of the TIPs 35 and TIPs 100 exchange‐traded funds into the i60 Fund. This conversion occurred at the Toronto Stock Exchange on March 6, 2000. Forty stocks of the TIPs 100 Fund that were not members of the new units of the i60 Fund were sold to complete this conversion. I find that a decrease in demand produced a permanent stock price decline, which was accompanied by significant abnormal trading volume. The results provide support for the downward‐sloping demand curve hypothesis.  相似文献

We explore factors affecting liquidity by examining the relation between liquidity changes and changes in firm characteristics around mergers and acquisitions. We find that spreads decline as the number of analysts, number of shareholders, number of market makers, firm size, and volume increase or as volatility decreases. Increased volume and firm size, and decreased volatility, are associated with increased depth. We find no evidence diversifying and non-diversifying mergers affect liquidity differently. We note that mergers and acquisitions are associated with reductions, on average, in spreads but that the reductions are fully explained by the accompanying changes in firm characteristics.  相似文献

Credit Ratings and Stock Liquidity   总被引:6,自引:0,他引:6  
We analyze contemporaneous and predictive relations betweencredit ratings and measures of equity market liquidity and findthat common measures of adverse selection, which reflect a portionof the uncertainty about future firm value, are larger whencredit ratings are poorer. We also show that future rating changescan be predicted using current levels of adverse selection.Collectively, our results validate widely used microstructuremeasures of adverse selection and offer new insights into thevalue of credit ratings and the specific nature of the informationthey contain.  相似文献

The MidCap 400 stock index is used to provide new evidence on the relation between stock index futures trading and stock return volatility. The study documents a significant decrease in return volatility and systematic risk, and a significant increase in trading volume for the MidCap 400 stocks after the introduction of the MidCap index. A control sample of medium-capitalization stocks, however, exhibits similar contemporaneous changes in these measures. The MidCap stocks and the control stocks also experience a significant decrease in volatility and an increase in volume after the introduction of MidCap 400 index futures. Thus, the study finds no difference in the behavior of the MidCap 400 stocks and the control stocks and no evidence of a relation between index futures trading and volatility in the stock market.  相似文献

Stock Market Declines and Liquidity   总被引:1,自引:0,他引:1  
Consistent with recent theoretical models where binding capital constraints lead to sudden liquidity dry-ups, we find that negative market returns decrease stock liquidity, especially during times of tightness in the funding market. The asymmetric effect of changes in aggregate asset values on liquidity and commonality in liquidity cannot be fully explained by changes in demand for liquidity or volatility effects. We document interindustry spillover effects in liquidity, which are likely to arise from capital constraints in the market making sector. We also find economically significant returns to supplying liquidity following periods of large drops in market valuations.  相似文献

This study examines the pattern of stock price behavior for a sample of 71 firms that moved from NASDAQ and NASDAQ/NMS to the American Stock Exchange (AMEX) between 1982 and 1987. The study tests the liquidity gains hypothesis, which states that investors expect liquidity gains for the less liquid over-the-counter stocks but not for their more liquid counterparts after their listing on the AMEX. The results support the hypothesis by showing a significant difference between the two groups of stocks on the day the AMEX announced approval of the listing. Thus, companies with low liquidity are the largest beneficiaries of listing. The evidence provides little support for the anomalous negative pattern of returns during the post-listing period reported in previous studies.  相似文献

This paper examines liquidity externalities by analyzing trading costs after hours. There is less than 1/20 as many trades per unit time after hours as during the trading day. The reduced trading activity results in substantially higher trading costs: quoted and effective spreads are three to four times larger than during the trading day. The higher spreads reflect greater adverse selection and order persistence, but not higher dealer profits. Because liquidity provision remains competitive after hours, the greater adverse selection and higher trading costs provide a direct measure of the magnitude of the liquidity externalities generated during the trading day.  相似文献

This study examines the motive of stock splits made by REITs. We find that REIT liquidity increases after the split announcement. However, the increase in liquidity is limited to days around the split announcement. After the ex-date, the liquidity tends to revert back to the pre-split level. We find that the positive market reaction around the announcement date is positively related to the change in short-term liquidity but not to the change in long-term liquidity. The announcement effect is also not correlated with future changes in operating performance. Overall, our results suggest that REITs split their share to attract investors’ attention rather than to signal or to improve trading liquidity in the long run.  相似文献
