Sentiment-scaled CAPM and market mispricing

This study explores the conditional version of the capital asset pricing model on sentiment to provide a behavioural intuition behind the value premium and market mispricing. We find betas (β) and the market risk premium to vary over time across different sentiment indices and portfolios. More importantly, the state β derived from this sentiment-scaled model provides a behavioural explanation of the value premium and a set of anomalies driven by mispricing. Different from the static β–return relation that gives a flat security market line, we document upward security market lines when plotting portfolio returns against their state βs and portfolios with higher state βs earn higher returns.     

Predicting mispricing of initial public offerings

This article investigates the ability of neural network models to predict mispricing of initial public offerings (IPOs). The aim is to improve the modest explanatory power of existing models that are based on the theory of asymmetrically informed economic agents surrounding post‐issue market value of IPOs. This study develops and compares linear regression and neural network models. The results show that modelling variable interactions and non‐linearity allows a potentially fruitful approach for stagging in IPOs. Neural networks have been criticized for being a black box; however, this paper shows that, by using sensitivity analysis, neural networks can provide a reasonable explanation of their predictive behaviour and direction of association between variables.

The real impact of stock market mispricing — Evidence from Australia

Using a large panel of Australian firms, we investigate if mispricing in the stock market has an impact on firm-level investment. A significantly positive relation is documented between investment and the proxies for mispricing, suggesting that overpriced (underpriced) firms tend to overinvest (underinvest). Furthermore, we find that equity-dependent firms display a more pronounced sensitivity of investment to stock misvaluation than do nonequity-dependent firms. Taken together, our findings evidence that mispricing in Australian capital markets may have significant influence on the real economy, and the influence works though an equity-financing channel.     

Exchange-traded fund ownership and underlying stock mispricing

In response to the increasing proliferation of exchange-traded funds (ETFs), and a warning from the Wall Street hero Michael Burry that passive investing has put the stock market into ‘bubble’ territory, we examine the relation between stock ownership by ETFs and mispricing from 2002 to 2018. We find that increased ETF ownership induces overpricing in underlying stocks. We then identify three mechanisms for this relationship: the overpricing of stocks attributable to increased ETF ownership is stronger for stocks that experience an increase in passive ETF ownership; during periods characterised by high investor sentiment; and for illiquid stocks. Our results are robust to a battery of tests including alternative measures for all key variables and are not confounded by the global financial crisis. Additional analyses show that mispricing caused by ETF ownership change is not driven by firm fundamentals and does not exacerbate stocks' information environment around earnings announcement.     

Stock performance and the mispricing of accruals

I investigate the relationship between contemporaneous stock-price performance and the persistence of accrued earnings, and its impact on the accrual anomaly. I find that, in a fiscal year, accrued earnings for stocks that have performed poorly are less persistent in predicting future earnings than accrued earnings for stocks that have performed moderately. I further find that a hedge-strategy based on accruals earns greater abnormal returns following bad-news years. The results are consistent with conservative accounting causing accrued earnings to be even less persistent in bad-news years and investors failing to efficiently price this differential in persistence.     

Value at risk,mispricing and expected returns

This study investigates how the relation between value-at-risk (VaR) and expected returns differs under different mispricing statuses. We find that a significantly negative VaR-return relation, defined as the VaR effect, is observed only for overpriced stocks, but not for underpriced stocks. Moreover, VaR has an amplification effect on mispricing, indicating that VaR captures risk that deters arbitrage and thus leads to an increase in mispricing. Our results are robust to alternative VaR definitions, subperiod analysis, different market states, and after controlling for other firm characteristics, well-known risk factors, and those variables that have been shown to have amplifying effects on mispricing. Finally, this study also examines the pricing effect of short sale constraints on the VaR effect under different mispricing statuses. Our findings suggest that the VaR effect observed in overpriced stocks becomes more severe as short sales are more constrained.     

Asset mispricing in peer-to-peer loan secondary markets

This study examines the presence of mispricing on Bondora, a leading European peer-to-peer lending platform, over the 2016–2019 period. By implementing machine learning methods, we measure the likelihood of success for loan resale on Bondora's secondary market and compare our predictions with the ex-post market outcomes. The differences observed uncover two phenomena which are related to the diverging perceptions of market participants on asset prices and associated fundamentals: some non-saleable assets are sold, while the resale of highly saleable assets is not successful. Sellers' pricing behaviour changes once they observe buyers' actions revealing the buyers' beliefs about the value of the asset. Our results are robust to various statistical and machine learning methods.     

The mispricing of U.S. Treasury bonds: a case study

This article documents an apparent pricing anomaly involving9? percent, 30-year Treasury bonds during the months of Mayand June 1986. During this period, the price of the 9?s rosesharply relative to the prices of other long-term Treasury bondsand created a potential arbitrage opportunity. In addition,owners of the 9? bonds were able to borrow at a zero interestrate by pledging their bonds. Detailed examination reveals thatthis relative pricing anomaly cannot be attributed to changesin the level or term structure of interest rates or to differencesbetween the bonds with respect to liquidity, taxation, or duration.     

Accrual mispricing,value-at-risk,and expected stock returns

We investigate the extent to which a parsimonious measure of maximum likely loss that captures the tail risk of returns—known as value-at-risk (VaR)—explains the relationship between accruals and the cross-sectional dispersion of expected stock returns. We construct portfolios based on Sloan’s (Account Rev 71(3):289–315, 1996) total accruals (TA) measure and individual asset-level VaR, which reflects the dynamic behavior of the asset distribution. We document that VaR is in congruence with portfolio-level accruals and that there is a significant positive relationship between VaR and the cross-section of portfolio returns. Allowing a double-sort involving VaR and TA further suggests that the spread between low- and high-TA portfolios is significantly attenuated after controlling for VaR. We also conduct a firm-level cross-sectional regression analysis and demonstrate that the TA- and VaR-based characteristics—but not the factor-mimicking portfolios—are compensated with higher expected returns, and that VaR neither subsumes nor is subsumed by TA. Finally, our cross-sectional decomposition analysis suggests that the firm-level VaR captures at least 7% of the accrual premium even in the presence of size and book-to-market. These findings lend support for the mispricing explanation of the accrual anomaly.

     

A model for determining mispricing of sovereign risk loans

Banks are known to use non-price terms in arriving at an effective loan rate. We demonstrate that international commercial banks use similar ‘credit rationing’ terms in pricing medium-term sovereign debt. Specifically, bankers adjust the loan rate, the maturity, and grace period in order to accommodate borrowers, specific needs while maintaining a fair return for the risk of the loan. These taken together comprise an all-in effective loan rate. We present a unique model using two stage least squares, which can easily be used to determine loan mispricing. The model is demonstrated using simulated loan pricing data.     

The duration of option portfolios

Duration is a value-weighted measure of average maturity which is commonly associated with portfolios of fixed-income securities. However, the concept finds application in option pricing theory also. This article shows that if options are valued by the Black (1976) formula and a comparative-statics methodology is employed, then the interest rate sensitivity of a portfolio of European options is equal to its duration. If the options are instead valued through the Black-Scholes (1973) formula, then the interest rate sensitivity is equal to only the ‘bond-equivalent duration’ inherent in a dynamic replication strategy for the option portfolio.     

Capital structure,equity mispricing,and stock repurchases

We evaluate motives for share repurchases using a unified framework where a firm has a target capital structure and has equity that can be mispriced. We document that capital structure adjustments are a value-increasing motive for repurchases and that the extent to which adjusting capital structure through a repurchase creates value depends on the undervaluation of the firm. Underlevered and undervalued firms enjoy the greatest economic gains from a repurchase, as evidenced by the stock price reaction to the repurchase announcement, and these firms are more likely to announce a share repurchase program.     

Equilibrium mispricing in a capital market with portfolio constraints

This article develops a general equilibrium, continuous timemodel where portfolio constraints generate mispricing betweenredundant securities. Constrained consumption-portfolio optimizationtechniques are adapted to incorporate redundant, possibly mispricedsecurities. Under logarithmic preferences, we provide explicitconditions for mispricing and closed-form expressions for alleconomic quantities. Existence of an equilibrium where mispricingoccurs with positive probability is verified in a specific case.In a more general setting, we demonstrate the necessity of mispricingfor equilibrium when agents are heterogeneous enough. The constructionof a representative agent with stochastic weights allows usto characterize prices and allocations, given mispricing occurs.     

Accrual mispricing: Evidence from European sovereign debt crisis

PurposeThis paper examines the accrual anomaly on the European market and the impact of the financial crisis on its dynamics.Design/methodology/approachUsing a sample of public European firms, during the period 2005-2016, this paper follows Sloan (1996) seminal work and measures accruals as Dechow, Sloan and Sweeney (1995).FindingsThere is no evidence that accrual anomaly persists on European markets. The study shows that, contrary to previous research, investors are not underweighting the accrual component of earnings and that accruals are not a good predictor of future stock returns.Research limitations/implicationsOur study has two limitations. First, due to the lack of data, the original sample was reduced to about one third. Second, results must be interpreted carefully since the sample period may be seen as an outlier case attributed to the crisis. Research on future years may unveil a conclusion on this.Practical implicationsResults suggest that transaction costs and idiosyncratic risk are no longer a barrier to investors. Results also point toward a possible new outcome in investor´s behaviour during crisis. Economically, given the lower returns that can be obtained on today markets, it makes sense that investors may reduce their risk aversion levels to get more returns.Originality/valueThis study contributes to the ongoing debate about accruals anomaly and market efficiency. To the best of our knowledge, it provides an original contribution to the literature by framing the accrual anomaly during the European debt crisis.     

Issuing and repurchasing: The influence of mispricing,corporate life cycle and financing waves

This paper examines the impact of mispricing, corporate life cycle, and financing waves on the debt/equity decision when firms (1) acquire funds and (2) repurchase funds by using a large international data set from 47 countries for the period 1984–2006. Our results support the mispricing hypothesis and the corporate life cycle hypothesis for both the acquisition of new funds and the repurchase of funds. However, our findings are consistent with the financing wave hypothesis only for repurchases of firms residing in common law countries as well as market-based countries.     

The comovement of option listed stocks

This study examines the changes in return comovement around the listing and delisting of stock option contracts. We show that newly option listed stocks experience an increase in comovement with a portfolio of option listed stocks and a decrease in comovement with the portfolio of non-optioned stocks. Similarly, stocks that undergo option delisting exhibit a decrease in comovement with option listed stocks and an increase in comovement with non-optioned stocks. We verify the reliability of our findings in several ways. A matched sample analysis suggests that our results are not driven by factors other than option listing and we find similar results using a calendar-time approach. Further analysis reveals that commonalities in option trading may induce the comovement in the option listed stocks. Overall, our evidence is consistent with the predictions of the category or habitat view of comovement.     

The information content of option ratios

A broad stream of research shows that information flows into underlying stock prices through the options market. For instance, prior research shows that both the Put–Call Ratio (P/C) and the Option-to-Stock Volume Ratio (O/S) predict negative future stock returns. In this paper, we compare the level of information contained in these two commonly used option volume ratios. First, we find that P/C ratios contain more predictability about future stock returns at the daily level than O/S ratios. Second, in contrast to our first set of results, O/S ratios contain more predictability about future returns at the weekly and monthly levels than P/C ratios. In fact, our tests show that while P/C ratios contain predictability about future daily returns and, to some extent, future weekly returns, the return predictability in P/C ratios is fleeting. O/S ratios, on the other hand, significantly predict negative returns at all levels: daily, weekly, and monthly. While Pan and Poteshman (2006) show that signed P/C ratios, which require proprietary data, have predictive power, we find that unsigned P/C ratios, which do not require proprietary data, also have predictive power.     

The role of reconciliation quality in limiting mispricing of non-GAAP earnings announcements by EURO STOXX firms

This empirical study investigates the relationship between the market mispricing of pro forma earnings announcements and the degree to which pro forma earnings are quantitatively reconciled with GAAP (Generally Accepted Accounting Principles) earnings. For a sample of EURO STOXX Fixed Index companies we find evidence of positive abnormal returns related to pro forma earnings disclosures, and, upon further analyses, conclude that this evidence is generally more consistent with the notion of market mispricing than omitted risk factors. Moreover, when reconciliation quality is controlled, market mispricing is found to be prevalent and pronounced only for low quality reconciliations. This finding suggests that reconciliation is important in reducing market mispricing.
