Short‐Selling Risk

Short sellers face unique risks, such as the risk that stock loans become expensive and the risk that stock loans are recalled. We show that short‐selling risk affects prices among the cross‐section of stocks. Stocks with more short‐selling risk have lower returns, less price efficiency, and less short selling.     

Short‐Selling Bans Around the World: Evidence from the 2007–09 Crisis

Most regulators around the world reacted to the 2007–09 crisis by imposing bans on short selling. These were imposed and lifted at different dates in different countries, often targeted different sets of stocks, and featured varying degrees of stringency. We exploit this variation in short‐sales regimes to identify their effects on liquidity, price discovery, and stock prices. Using panel and matching techniques, we find that bans (i) were detrimental for liquidity, especially for stocks with small capitalization and no listed options; (ii) slowed price discovery, especially in bear markets, and (iii) failed to support prices, except possibly for U.S. financial stocks.     

Long‐ and Short‐Term Cost Efficiency Frontier Evaluation: Evidence from Spanish Local Governments*

This paper analyses the efficiency of Spanish local governments using non‐convex frontier methods. More specifically, it analyses the total cost inefficiency and proposes its decomposition into three additive components: short‐term variable cost inefficiency; capacity utilisation of fixed inputs; and scale inefficiency. The second and third components correspond to the long‐term cost efficiency notion. The proposition is applied to a sample of Spanish municipal councils (municipalities with over 2,000 inhabitants located in Catalonia, the Spanish north‐eastern region). The results confirm the existence of significant cost inefficiency coefficients related to both the long and short term.     

The Beauty Contest and Short‐Term Trading

Short‐termism need not breed informational price inefficiency even when generating beauty contests. We demonstrate this claim in a two‐period market with persistent liquidity trading and risk‐averse, privately informed, short‐term investors and find that prices reflect average expectations about fundamentals and liquidity trading. Informed investors engage in “retrospective” learning to reassess inferences (about fundamentals) made during the trading game's early stages. This behavior introduces strategic complementarities in the use of information and can yield two stable equilibria that can be ranked in terms of liquidity, volatility, and informational efficiency. We derive implications that explain market anomalies as well as empirical regularities.     

The Role of Short‐Termism in Financial Market Crises

The purpose of this paper is to examine the contribution short‐termist behaviours have had in various financial market crises. The early warning signs and drivers of short‐termism are investigated, as well as ways to mitigate short‐termist behaviour and consequences in the future. Short‐termism as defined for the purposes of this paper is the excessive focus on short‐term performance, earnings and other metrics at the expense of attention being given to the development of a long‐term strategy that promotes sustainable long‐term value creation.     

Short Selling and the Weekend Effect for NYSE Securities

Using short-sale transactions data, we examine the relation between short selling and the weekend effect. We do not find that short selling is more abundant on Monday than on Friday, even for stocks that have higher Friday returns. We find that short sellers execute more short-sale volume during the middle of the week, and that the positive correlation between short selling and returns on Monday is greater, on average, than the correlation on the other days of the week. Our results are robust to subsamples of stocks with larger weekend effects and stocks that do not have listed options.     

Short‐ and Long‐Term Effects of Multimarket Trading

We analyze short‐ and long‐term effects of multimarket trading by examining the entries of multiple markets into transacting three ETFs, DIA, QQQ, and SPY. We find that large‐scale entries improve overall market quality, while small‐scale entries have ambiguous effects. Our results show that the competition effect dominates the fragmentation effect over a long horizon and that market fragmentation leads to a decline in trading costs. Further, we find that the order handling rules help mitigate the fragmentation effect and facilitate the competition effect. We do not find that multimarket trading harms price efficiency or increases price volatility.     

The Determinants of Execution Costs in Short‐Term Money Markets

Prior research attributes the observed negative relation between execution costs and trade size in opaque markets to two factors—information asymmetry and broker‐client relationships. We provide evidence that a trader's ex ante transaction price information and the relationship traders have with their brokers are both significant determinants of a trader's execution costs in an opaque market; however, traders who establish strong relationships with their brokers will achieve a greater reduction in execution costs than traders with ex ante transaction price information. We also find evidence that trade size has little explanatory power after controlling for a trader's ex ante transaction price information and broker‐client relationships.     

Funding Liquidity without Banks: Evidence from a Shock to the Cost of Very Short‐Term Debt

In 2011, Colombia instituted a tax on repayment of bank loans, which increased the cost of short‐term bank credit more than long‐term credit. Firms responded by cutting short‐term loans for liquidity management purposes and increasing the use of cash and trade credit. In industries in which trade credit is more accessible (based on U.S. Compustat firms), we find substitution into accounts payable and little effect on cash and investment. Where trade credit is less available, firms increase cash and cut investment. Thus, trade credit provides an alternative source of liquidity that can insulate some firms from bank liquidity shocks.     

The Effects of Public Information with Asymmetrically Informed Short‐Horizon Investors

This paper analyzes the effects of public information in a perfect competition trading model populated by asymmetrically informed short‐horizon investors with different levels of private information precision. We first show that information asymmetry reduces the amount of private information revealed by price in equilibrium (i.e., price informativeness) and can lead to multiple linear equilibria. We then demonstrate that the presence of both information asymmetry and short horizons provides a channel through which public information influences price informativeness and equilibrium uniqueness. We identify conditions under which public information increases or decreases price informativeness, and when multiple equilibria may arise. Our analysis shows that public information not only directly endows prices with more (public) information, it can also have an important indirect effect on the degree to which prices reveal private information.     

Canonical Valuation of Mortality‐Linked Securities

A fundamental question in the study of mortality‐linked securities is how to place a value on them. This is still an open question, partly because there is a lack of liquidly traded longevity indexes or securities from which we can infer the market price of risk. This article develops a framework for pricing mortality‐linked securities on the basis of canonical valuation. This framework is largely nonparametric, helping us avoid parameter and model risk, which may be significant in other pricing methods. The framework is then applied to a mortality‐linked security, and the results are compared against those derived from other methods.     

Short‐selling constraints and corporate payout policy

This study shows that managers adjust corporate payout policies to counteract intensified short‐selling pressures following the removal of a short‐selling constraint. We use a controlled experiment, the Regulation SHO pilot program, to find that changing the short‐selling rule brings small companies to increase cash dividends, but not to repurchase more shares. Because paying dividends is costly, it is acknowledged as a more reliable signal of stock undervaluation than share repurchase. While our evidence suggests that companies select this payout strategy to deter predatory short sellers, it also shows that a short‐selling activity has a causal effect on corporate payout decisions.     

Short‐Term Corporate Debt around the World

Short‐term corporate debt as a proportion of total debt issued by public firms varies greatly across countries, between 28% in the United States and 78% in China. This paper argues that the interaction between information asymmetry and legal protection of creditors is an important determinant of debt maturity. When short‐term debt plays a dual role as signaling and commitment devices, a reduction in information asymmetry has a larger impact on debt maturity when creditor rights are weaker. We find empirical support for this prediction using firm‐level data from 45 countries around the world.     

Short‐Term Market Risks Implied by Weekly Options

We study short‐maturity (“weekly”) S&P 500 index options, which provide a direct way to analyze volatility and jump risks. Unlike longer‐dated options, they are largely insensitive to the risk of intertemporal shifts in the economic environment. Adopting a novel seminonparametric approach, we uncover variation in the negative jump tail risk, which is not spanned by market volatility and helps predict future equity returns. As such, our approach allows for easy identification of periods of heightened concerns about negative tail events that are not always “signaled” by the level of market volatility and elude standard asset pricing models.     

Short‐Horizon Return Predictability in International Equity Markets

This study measures the degree of short‐horizon return predictability of 50 international equity markets and examines how its variation is related to the indicators of equity market development. Two multiple‐horizon variance ratio tests are employed to measure the degree of return predictability. We find evidence that return predictability is negatively correlated with publicly available indicators of equity market development. Our cross‐sectional regression analysis shows that the per capita gross domestic product, market turnover, investor protection, and absence of short‐selling restrictions are correlated with cross‐market variations in return predictability.     

Short‐Term Performance of U.S.‐Bound Chinese IPOs

Firms from emerging markets, including China, increasingly seek to raise capital outside of their home markets. We examine the short‐term performance of U.S.‐bound Chinese initial public offerings (IPOs) and find that these IPOs have significantly lower underpricing than a matched sample of U.S. counterparts. We also find that the magnitude of IPO underpricing for U.S.‐bound Chinese firms is positively related to revisions in offer price.     

Trust‐Preferred Securities and Insurer Financing Decisions

We analyze insurance holding company (IHC) issuance of trust‐preferred securities (TPS) from 1994 to 2013. We find that larger and more financially levered IHCs issued TPS in 1996 and 1997, as well as those that obtained financial strength ratings from A.M. Best. Abnormal stock price returns are positively related to financial distress costs, growth opportunities, and tax burden, but negatively related to size. Consistent with the pecking order theory, intent to use TPS proceeds to retire debt is positively related to abnormal stock returns, whereas intent to use proceeds to retire preferred equity is negatively related to abnormal stock returns.     

Chief Financial Officers’ Short‐ and Long‐term Incentive‐based Compensation and Earnings Management

This study examines the association between chief financial officers’ (CFOs) short‐ and long‐term compensation and discretionary current and non‐current accruals. The CFO's cash bonus is used as a measure of short‐term incentives and shares plus options is used as a measure of long‐term incentives. The results show a significant and positive association between CFOs’ short‐term compensation and the absolute value of discretionary current accruals. The results also show a significant and positive association between CFOs’ long‐term compensation and the absolute value of discretionary non‐current accruals. STUDY provides evidence that the earnings management behaviour of CFOs is associated with type of CFO compensation.
