本文研究了市场流动性风险与投资者结构模式之间的关系。随着机构投资者的不断发展壮大,我国投资者结构模式发生了重要转变,然而新的投资者结构模式下,市场流动性的波动结构是否有所不同?本文以流动性水平变化率为研究对象,构建了包含虚拟变量的TGARCH模型对其波动方程进行拟合,研究发现:机构投资者壮大后市场流动性风险显著降低;机构占主导后市场流动性风险受新信息的影响权重较之前增大,而旧有信息对流动性风险的影响相比以前减小。  相似文献

The paper investigates the relation between retail investors’ participation in trading and aggregate stock market liquidity. The findings show a positive and significant relation between retail investors’ trading and stock market liquidity. Examination of the determinants of retail investors’ trading reveals that, on average, retail investors with more diversified trading activity tend to trade when liquidity is higher, the frequency of their arrival to the market is not affected by the level of liquidity, and retail investors are willing to trade at a lower liquidity level as sellers than as buyers. Moreover, retail investors’ trading does not create price noise at the aggregate market level. Overall, the evidence suggests that retail investors contribute to market quality.  相似文献

Defining asymmetry of feedback trading (AFC) as the difference between buying-winners and selling-losers intensities, the paper investigates if AFC impacts stock pricing. We show that buying stocks with low AFC and selling stocks with high AFC makes significant positive returns after controlling traditional pricing factors. The return mainly comes from the long leg and cannot be simply attributed to either mispricing, liquidity, or risk premium. Further study shows that the negative impact of AFC on future stock return is reinforced with an increase in past returns, maximum daily return, relative valuation level, asset growth rate, or operating profit rate. As AFC represents retail trading intensity, the results imply that the inactiveness of retail investors may make price relative underreaction to good news and thus lead to positive expected stock return.  相似文献

This paper investigates the role of liquidity provisions played by individual investors prior to dividend announcements in Taiwan. We first document a positive relationship between aggregate individual trading before dividend announcements and abnormal stock returns in the one month after the events. We find that this positive relationship varies with liquidity. We then decompose the abnormal returns following the event into information and liquidity provision components. The information component is not significant at all, but the liquidity component is positively significant, which shows that it is individual investors’ provisions of liquidity to institutional investors prior to dividend announcements that drives the positive relationship between pre-event individual trading and post-event returns.  相似文献

We investigate whether the funding liquidity risk to institutional investors influences the negative relation between expected returns and variance (the ‘‘Low-volatility anomaly’’). With the Taiwan stock market as a setting, we implement a multivariate Markov switching model and use the funding liquidity risk to model the time-varying transition probabilities of the regime-switching process to capture changes in the funding liquidity risk regime. Our evidence documents that the low-volatility anomaly is most pronounced when there is high funding liquidity risk. When there is low funding liquidity risk, however, the low-volatility anomaly has a significant reversal. These results imply that the increased funding liquidity risk due to financial shock transmitted from parent banks is associated with higher selling pressure on institutional investors’ high-volatility stocks, leading to the low-volatility anomaly.  相似文献

Using an extensive, time-series, cross-sectional data-set of actively traded Indian stocks with up to 1.75 million firm-day observations, we discern the key determinants of commonality in liquidity among emerging markets. The paper shows evidence for both supply-side and demand-side factors contributing to liquidity commonality. However, the results are more supportive towards supply-side rationale for liquidity commonality among the firms where regulators and banks play an important source of commonality in liquidity, especially during market turmoil. Results are partially driven by the fact that the Indian stick exchange is an order-driven market. Economic activities like cheap exports and undervalued currency, rather than correlated trading by the institutional investors determine the demand for liquidity. These findings endorse the effect of high firm value, market return, liquidity, volatility, turnover, and alternate proxies of commonality in liquidity estimation.  相似文献

In this study, we examine the relation between the price of liquidity, or illiquidity return premium, and the economic policy uncertainty (EPU). On average, an illiquid portfolio earns a 0.597% higher monthly return than a liquid portfolio. The results further show that the EPU index has a positive relationship with the illiquidity return premium. This indicates that investors require higher compensation for holding illiquid stocks when there is a higher economic uncertainty. We also show that EPU affects the illiquidity return premium through the market illiquidity channel. The rise of EPU could increase the risk of illiquid stocks and make investors more risk-averse, thereby requiring higher compensation for illiquidity. Finally, it is found that the relationship between EPU and the illiquidity return premium is stronger when market liquidity is impaired and during crises.  相似文献

We investigate the association of foreign share ownership with firm‐level disclosure and corporate governance structures in Zimbabwe, a developing country in Southern Africa. Our motivation for the study derives from the literature, which suggests that foreign investors: (1) generally have a preference for companies in which they are well informed and where their investments are more likely to be protected, and (2) avoid companies in developing countries because of weak corporate governance structures and low disclosure. Using data drawn from companies listed on the Zimbabwe Stock Exchange, we examine the effect of disclosure and corporate governance on foreign share ownership. We find that disclosure, proportion of non‐executive directors, institutional share ownership and audit committee independence are all positively and significantly associated with foreign share ownership. Our results also demonstrate that market capitalization, return on equity and liquidity ratios are significantly associated with foreign share ownership. These results are consistent with the notion that foreign investors have a preference for companies with effective corporate governance structures, companies with less information asymmetry, as well as companies with healthy cash positions. The results have implications for policy‐makers in developing countries in their endeavour to improve liquidity on stock markets through the participation of foreign investors. The results are also useful to managers in developing countries who are keen to increase the market value of their company, thereby reducing their cost of capital.  相似文献

研究短期内机构投资者行为与不同规模公司股价的相互影响.在机构投资者对股价的影响方面,阐释并论证了机构持股比例增量与当日股价的正相关关系,指出机构对大盘股的影响强于对小盘股的影响.机构资金流入(流出)的定性信息本身对股价上升(下降)有额外的促进作用;相对于撤资而言,股价对机构的注资行为更敏感;而对小盘股,该不对称性更加明显.此外,当日收益率和前三天内的机构资金流入存在负相关关系,且该种负关系在大盘股中的表现比在小盘股中更为明显.在股价对机构投资者行为的反馈作用方面,以实证结果阐明了股价上升(下降)的信息本身可对机构行为有缓冲作用,且该作用对小盘股影响大于对大盘股的影响.研究显示,在短期内机构更倾向于动量交易,这在小盘股中尤为明显.三天前收益率对当日机构行为的影响颇为明显,且与一天前的收益率的影响力相当;相对而言,两天前收益率对机构行为的影响不甚明显.  相似文献

We examine the sensitivities of aggregate balances of retail and institutional money market funds (MMFs) and their potential substitutes, bank deposits, to changes in short-term interest rates while controlling for calendar-time effects. We find that institutional MMF and time deposit cash flows are sensitive to recent changes in short-term interest rates. Institutional MMF investors appear to take advantage of arbitrage opportunities created by MMFs using the amortized cost technique. Retail MMF investors are much less responsive to changes in interest rates.  相似文献

Using a composite disclosure quality measure, we examine the effect of disclosure quality on price delay and the effect of price delay determined by disclosure quality on expected returns in the Taiwan stock market. We find that higher disclosure quality can reduce stock price delay through more investor attention and higher stock liquidity after we control for accounting quality variables and consider the endogeneity issue. Furthermore, we show that disclosure quality reduces expected stock returns through the price efficiency channel associated with both investor attention and stock liquidity. Our results indicate that increasing a firm’s standardized information rating by one standard deviation can reduce its expected stock return by 0.63% annually. Taken together, our evidence suggests that regulatory activities enforced to improve public firms’ disclosure quality in the Taiwan stock market can make the stock market more efficient and therefore lower investors’ required return for stocks.  相似文献

Stock price crash sensitivity refers to the conditional probability of a stock crash when the market collapses. It focuses on individual stocks' sensitivity to the market crash and can affect stock pricing significantly. Although the crash sensitivity of China's stock market is very high as a whole (Weigert, 2016), different individual stocks show varying degrees of crash sensitivity. This paper, adopting the perspective of institutional investors, explores the reasons for the difference in crash sensitivity in China's stock market, and finds that: First, institutional investors' shareholdings is positively related to firms' stock price crash sensitivity. However, after dividing institutional investors into professional (represented by financial institutions) and non-professional institutional investors (represented by general legal persons), we find that only professional institutional investors' shareholdings is negatively related to firms' stock price crash sensitivity. Second, the impact of professional institutional investors on the crash sensitivity is influenced by stock liquidity and media sentiment: when the stock liquidity of listed companies is good or the media sentiment is strong, the negative impact of professional institutional investors on the crash sensitivity is accordingly high. This paper, by highlighting the investor structure, attempts a pioneering exploration of the influencing factors of the difference in stock price crash sensitivity in China. Our empirical results enrich research on stock price crash sensitivity and the heterogeneity of institutional investors. They can also serve to guide regulatory authorities' development of institutional investors and efforts to maintain market stability.  相似文献

In 1996, the first exchange-traded funds (ETFs) designed to track a subset of the Morgan Stanley Capital International country indices were approved under the name World Equity Benchmarks (acronym “WEBS”™). We examine the impact of early WEBS-trading on the liquidity of corresponding closed-end country funds (CECFs), previously one of the main avenues for retail investors to achieve country-specific equity exposure. We document a decline in both the trading volume and the trading frequency for CECFs, suggesting that some investors migrate to WEBS. At the same time, the market depth for CECFs increases and the bid-ask spread for CECFs decreases following the introduction of WEBS. Our results support the hypothesis that despite the decline in volume and trading frequency, the liquidity of CECFs is favorably affected by the advent of WEBS.  相似文献

We examine the pattern of daily stock returns in Japan, Hong Kong, and Taiwan. Our results support the information-processing hypothesis: Average returns on Monday are lower than on other days of the week, particularly when the previous trading day’s return is negative. Our results also support the positive-feedback-trading hypothesis: Daily returns exhibit positive autocorrelation, particularly when the previous trading day’s return is positive. Further analysis reveals that institutional investors (Japan), individual investors (Taiwan), or both (Hong Kong) can cause these patterns. Our findings are consistent with the relative importance of institutional and individual investors in each of these markets. We thank three anonymous reviewers for helpful comments and suggestions.  相似文献

Market timers without timing skill suffer a penalty relative to buy-and-hold investors in the form of higher portfolio risk. With transactions costs, timers suffer lower expected returns as well. We derive the magnitude of this penalty for a timer randomly switching funds between two or more risky assets. Assuming costless trades, a U.S.-based timer randomly switching between U.S. and Japanese national stock funds can expect to face a 26.2% higher standard deviation than a comparable buy-and-hold investor at the same level of expected return. A timer randomly switching between a globally diversified equity portfolio and U.S. T-bills faces a 50.3% higher standard deviation of return than a comparable buy-and-hold investor.  相似文献

以我国2009—2016年沪深上市公司数据为样本,探究了股价崩盘风险、信息环境对企业现金调整的影响。研究发现:股价崩盘风险越大,企业现金调整速度越快,且这种正相关关系对于分析师跟踪数量较少、机构投资者持股比例少的企业而言更为显著。进一步考察股权性质在企业现金调整速度中的影响,发现国有企业与民营企业面对股价崩盘风险的现金调整速度并不具有显著差异,但是对于民营企业而言,更多的分析师跟踪和机构投资者持股将显著降低企业应对股价崩盘风险的现金调整速度,信息环境对于国有企业的作用并不显著。  相似文献

We estimate expected short interest for Nasdaq stocks. Extending prior work, our research is among the first to investigate the impact of ownership structure on short-selling activity. We find that short interest is negatively related to institutional ownership and positively related to inside ownership; stocks with greater liquidity and smaller relative spreads are more heavily shorted. We also develop a measure of the unanticipated level of short selling; relative to the reported amount of short interest, this unexpected level of short selling seems at first to better represent the opinions of informed investors engaging in costly short-selling activities. However, the power of the unanticipated level of short-selling factor is displaced when we make allowances for traditional market, firm-size, and momentum variables.  相似文献

This paper examines the impact of gross foreign equity inflows on aggregate liquidity of the Malaysian stock market using newly assembled foreign trading data and the best performing bid-ask spread proxy. Employing vector autoregression, we discover a one-way causality from gross inflows to aggregate liquidity, and foreign investors erode liquidity of the Malaysian stock market. Additional analyses reveal that uncertainties in the U.S. markets negatively affect aggregate liquidity through the flows of foreign institutions, whose positive feedback trading destabilizes the local bourse. Despite the shocks, there is sufficient liquidity provision from local state-backed institutional funds and local proprietary day traders.  相似文献

Trading by institutions on the NSYE and Nasdaq markets has grown dramatically. Yet, while listing effects for firms moving to an exchange have been studied for more than 60 years, evidence on whether listing is beneficial is mixed. This study focuses on listing effects to institutional traders by examining different factors that capture changes in block execution. Results indicate price impacts and liquidity costs decline for various types of block trades and block trade sizes, the average volume of which increases after listing.(JEL G20)  相似文献
