本文通过套利均衡模型刻画了ETF折溢价的形成过程,分析了ETF折溢价预测未来ETF收益的条件,并利用投资组合和Fama-Mecbeth回归检验了ETF折溢价对未来ETF收益的可预测性。研究结果显示:ETF折溢价是噪声冲击和投资者对信息反应不足导致的错误定价,这种错误定价主要发生在ETF层面,错误定价的修正表现为折溢价对未来ETF收益有负向预测作用,溢价率越高,未来ETF收益越低,投资者利用多空对冲策略每周可以从ETF错误定价修正中获得0.94%的收益。同时,ETF折溢价对未来ETF收益预测具有持续性,平均而言,ETF折溢价对未来ETF收益的预测可以持续4周,意味着市场完全修正ETF错误定价至少需要4周时间。本文进一步从套利限制的角度解释了ETF折溢价对未来收益预测的持续性,发现套利限制越大,折溢价对ETF未来收益预测的持续性越强,投资组合获得的收益也越高。 相似文献

流动性与资产定价是当前金融领域研究的热点之一,研究流动性与资产定价以及流动性风险与资产定价的关系是当前国内研究资产定价的主要内容。本文将通过沪深股市的实证数据研究中国股票市场系统流动性风险溢价的问题。针对流动性溢价问题,本文将基于沪深股市数据,结合我国证券市场特征,按照Gibson和Mougeot的基本框架,直接建立二元均值GARCH——Diagonal BEKK模型,对我国股票市场的系统流动性风险溢价动态进行实证研究。通过研究,本文得出结论:中国股票市场存在系统流动性风险溢价,但随着样本期的选取、样本的选取以及不同流动性指标的选取的不同,其显著性是也不同的,系统流动性风险溢价对对市场的超额收益是有影响的,而且这种影响是动态波动的,从长期看,这种波动持续性的存在会使投资者未来投资的不确定性增加。 相似文献

A股公司盈余(EARN)和盈余构成(应计盈余ACC和现金盈余CFO)的错误定价与成熟资本市场并不完全一致。一致的地方在于确实存在“应计异象”。不一致的地方在于“应计异象”的相对性。在分年度的检验中,EARN、ACC和CFO的错误定价方向一致,CFO和EARN的错误定价程度基本相同,相对于CFO的错误定价程度,ACC被高估——出现高估的时候,ACC被高估的程度更大;出现低估的时候,CFO被低估的程度更大。一个简单的模型表明,由于这种相对的高估,ACC和CFO的错误定价可以出现三种组合。 相似文献

本文以2010-2020年我国A股上市公司为样本,实证检验了员工持股计划对公司股票错误定价的影响。研究发现,员工持股计划可以有效缓解公司股票错误定价,但员工持股规模并不是越大越好,而是存在一个临界点,超过这个临界点则会引发搭便车问题,即员工持股规模与股票错误定价呈U型关系。进一步分析发现,在董监高持股比例较低、自有资金筹资认购和民营企业中,上述关系表现更为显著,机制检验结果表明,员工持股通过提高内部控制有效性降低了股票错误定价。 相似文献

世界各国政府普遍对独立审计产业实施管制,我国也不例外。当前,学术界鲜有对我国政府管制的微观领域———审计产品定价管制的相关研究。鉴于此,本文概括、提炼相关管制政策的现状,分析价格管制模型对于审计产业的适用性,并考察了相关具体管制政策的实施效应。本文认为,由于不存在适用于审计产品的价格管制模型,并且价格管制难以实现预期政策效果,因此,审计产品定价的政府管制不仅是低效率的,也是不可行的。 相似文献

Low credit risk firms realize higher returns than high credit risk firms. This is puzzling because investors seem to pay a premium for bearing credit risk. The credit risk effect manifests itself due to the poor performance of low-rated stocks (which account for 4.2% of total market capitalization) during periods of financial distress. Around rating downgrades, low-rated firms experience considerable negative returns amid strong institutional selling, whereas returns do not differ across credit risk groups in stable or improving credit conditions. The evidence for the credit risk effect points towards mispricing generated by retail investors and sustained by illiquidity and short sell constraints. 相似文献

This paper examines seven instances in which the market value of a parent company was less than the market value of its publicly traded subsidiary. Efforts are made to explain this “parent company puzzle” in terms of taxes, agency costs, liquidity effects and noise trader risk. None of them work. The only explanation consistent with the evidence is a mispricing of the subsidiary shares associated with noise trader demand and impediments to arbitrage. As further evidence in support of this view, five corporate control transactions, all designed to exploit the apparent mispricing, were initiated while this research was in progress. 相似文献

This paper finds that stocks of repurchasers with high sensitivity to investor sentiment are more likely to be mispriced. Thus, such repurchases are followed by superior post-buyback stock performance. This abnormal return associated with sensitivity to sentiment cannot be explained by other undervaluation factors: book-to-market or prior return effects. My results are robust with factor model analysis and controls for contamination effects. I conclude that this sentiment-driven undervaluation may result from the difficulty to value and/or limits to arbitrage rather than investor overreaction. 相似文献

This paper examines whether the mispricing of accruals documented in equity markets extends to bond markets. The paper finds
that corporate bonds of firms with high operating accruals underperform corporate bonds of firms with low operating accruals.
In the first year after portfolio formation, the underperformance is 115 basis points using an accrual measure that includes
capital investments and 93 basis points using an accrual measure that is based only on working capital investments. The Sharpe
ratios of the zero-investment bond accrual portfolios are comparable to those of the corresponding zero-investment stock accrual
portfolios. The results are also robust to risk adjustments based on both a factor model consisting of the Fama and French
(J. Financial Econ 33 (1993) 3) stock and bond market factors and a characteristics model based on bond ratings and duration. Cross-sectional Fama–MacBeth
regressions that use individual bond data and control for stock and bond issuances in addition to ratings and duration also
confirm the time-series portfolio findings. Overall, our results reveal an accrual anomaly among bonds similar to that observed
among stocks.

The short of it: Investor sentiment and anomalies 总被引:2,自引:0,他引:2
This study explores the role of investor sentiment in a broad set of anomalies in cross-sectional stock returns. We consider a setting in which the presence of market-wide sentiment is combined with the argument that overpricing should be more prevalent than underpricing, due to short-sale impediments. Long-short strategies that exploit the anomalies exhibit profits consistent with this setting. First, each anomaly is stronger (its long-short strategy is more profitable) following high levels of sentiment. Second, the short leg of each strategy is more profitable following high sentiment. Finally, sentiment exhibits no relation to returns on the long legs of the strategies. 相似文献

This paper examines how arbitrage may contribute to, rather than remove, temporary price deviation between two related securities. Based on a unique sample of stock‐for‐stock tender offers by a member firm for another member firm within Korean family business groups, we find that arbitrage opportunity exists in more than three quarters of the sample, which is consistent with Lamont and Thaler (2003). Outside investors’ tendering decisions and institutions’ short‐selling are consistent with exploiting potential arbitrage opportunities, but not large enough to eliminate them. The prices of the two securities tend to diverge leading up to the tender offer, which may be impacted by the controlling families. This deviation, reflected in the exchange ratio of the two securities, is more likely to be sustained when there is more short‐selling during the possible arbitrage period. Our results suggest that arbitrage may support temporary deviations in the relative prices of two related securities under certain circumstances. 相似文献

本文运用2000-2013年中国A股上市公司年数据,研究了资本市场错误定价对不同融资约束水平公司融资方式选择的影响。研究发现,对于股权融资,无论融资约束水平高低,错误定价对公司股权融资均具有显著的正向影响;对于债务融资,股价高估会显著促进高融资约束公司的债务融资,包括长期债务融资和短期债务融资,而对低融资约束公司则不存在显著影响。同时还发现,错误定价对高融资约束公司短期债务融资的正向影响要远高于长期债务融资。这表明,在中国资本市场,资本市场错误定价对不同融资约束水平公司融资方式选择的影响存在显著差异,对高融资约束公司的影响表现为股权融资、短期债务融资、长期债务融资的融资优序现象,而对低融资约束公司则不存在这一现象。 相似文献

What market features of financial risk transfer exacerbate counterparty risk? To analyze this, we formulate a model which elucidates important differences between financial risk transfer and traditional insurance, using the example of Credit Default Swaps (CDS). We allow for (heterogeneous) insurer insolvency, which captures the possibility that relatively risky counterparties may exist in the market. Further, we find that stable insurers become less stable as the price of the contract decreases. The analysis includes insured parties that have heterogeneous motivations for purchasing CDS. For example, some may own the underlying asset and purchase CDS for risk management, while others buy these contracts purely for trading purposes. We show that traders will choose to contract with less stable insurers, resulting in higher counterparty risk in this market relative to that of traditional insurance; however, a regulatory policy that removes traders can, perversely, cause stable counterparties to become less stable. We conclude with two extensions of the model that consider a Central Counterparty (CCP) arrangement and the consequences of asymmetric information over insurer type. 相似文献

This paper tests Ahmed and Safdar's noise‐related fundamentals‐based explanation for the momentum premium in European equity markets. Consistent with the view that past price changes may be partially driven by noise, the future return behaviour of winners and losers is significantly dependent upon the degree to which past price performance is consistent with fundamentals. European momentum profits are concentrated among those firms where past price performance is congruent with fundamentals, but absent among those firms where past price performance is incongruent with fundamentals. The significantly different momentum premiums on congruent and incongruent fundamentals‐momentum strategies are attributable to the exploitation of existing mispricing among momentum stocks that can be ex ante identified using firm fundamentals. 相似文献
