This paper applies the Least Absolute Shrinkage and Selection Operator (LASSO) to make rolling one‐minute‐ahead return forecasts using the entire cross‐section of lagged returns as candidate predictors. The LASSO increases both out‐of‐sample fit and forecast‐implied Sharpe ratios. This out‐of‐sample success comes from identifying predictors that are unexpected, short‐lived, and sparse. Although the LASSO uses a statistical rule rather than economic intuition to identify predictors, the predictors it identifies are nevertheless associated with economically meaningful events: the LASSO tends to identify as predictors stocks with news about fundamentals. 相似文献

We investigate market selection and bet pricing in a repeated prediction market model. We derive the conditions for long-run survival of more than one agent (the crowd) and quantify the information content of prevailing prices in the case of fractional Kelly traders with heterogeneous beliefs. It turns out that, apart some non-generic situations, prices do not converge, neither almost surely nor on average, to true probabilities, nor are they always nearer to the truth than the beliefs of all surviving agents. This implies that, in general, prediction market prices are not maximum likelihood estimators of the true probabilities. However, when more than one agent survives, the average price emerging from a prediction market approximates the true probability with lower information loss than any individual belief. 相似文献

Wendell Bell's idealistic vision of the role of the sociologist in creating a brighter future for society and his theoretical framework of the role of intellectual elites in the decisions of nationhood are examined through the personal lens of a former Caribbean student of the West Indies Study Program at UCLA. 相似文献

The main purpose of this paper is using a unique data set from IPO filings to study the IPO market as a screening device and
the going public decision. We find that private firms that are less likely to have the option to access public equity markets
receive 54 cents for each dollar they expected to raise in an IPO, whereas firms that are more likely to have the option to
go public but sell privately sell at $1.11 for each dollar they expected to receive at the IPO. This result suggests that
the lower valuation for firms sold in private markets compared to firms sold in public markets can be at least partially explained
by the lower relative bargaining power of private firms. However, owners that took their firms public before selling received,
on average, 40% larger payoffs than owners that had the option to go public but decided to sell privately. The results in
this study indicate that these differences in valuation are not fully explained by existing theoretical models on the decision
to sell privately or in two stages. 相似文献

Our model, which is adapted from Feltham and Ohlson (Contemp Account Res 11:689–731, 1995) and Ohlson (Contemp Account Res 11:661–687, 1995) and extends Dechow and Dichev (Account Rev 77:35–59, 2002), characterizes the information about future cash flows reflected in accruals. It reveals investors can extract from accruals information about next period’s economic factor and the transitory part of one component of next period’s cash flow. The extent to which each accrual provides this information depends on whether the accrual aligns future or past cash flows and current period economics and whether it relates to the current or prior period. Thus each type of accrual has a different coefficient in valuation and forecasting cash flows or earnings. Each coefficient combines an information weight reflecting the information that accrual type provides and a multiple reflecting how that information is used in valuation and cash flow and earnings forecasting. The empirical evidence supports our main insight, namely that partitioning accruals based on their role in cash-flow alignment increases their ability to forecast future cash flows and earnings and explain firm value. 相似文献

We employ Merton's probability of default as a continuous ex‐ante measure of the likelihood of firm failure and dynamic panel generalised method of moments to better characterise the relationship between corporate governance and the chance of default. In doing so, we overcome limitations of discrete proxies widely used in previous studies and more completely account for endogeneity issues permeating this area of research. While initial testing designed to facilitate comparison with previous studies suggests a significant relationship between the probability of default and executive pay, board structure and ownership structure, once endogeneity concerns are accounted for, no such relationship remains. 相似文献

In this discussion that took place at the SASB 2016 Symposium, the former Chair of the Securities and Exchange Commission explores recent developments in corporate sustainability reporting with three Directors—two past and one current—of the SEC's Division of Corporation Finance (or “CorpFin”). The consensus of the panelists was that investors want companies to provide more and better disclosure of their ESG exposures, particularly climate change, and their plans to manage those exposures. According to the current director of CorpFin, the most common demand expressed in the thousands of “comment letters” elicited by the SEC's recent concept release was for more and better sustainability information. And among the many issues cited by investors in those letters, including economic inequality, corruption, indigenous rights, and community relations, the subject of greatest interest by far was climate change. While none of the panelists claimed to see private‐sector demand for SEC action and a new set of mandatory requirements, all seemed to agree that many companies would welcome the establishment of voluntary guidelines and standards for providing ESG information—and that the guidelines recently developed by the Sustainability Accounting Standards Board are a promising model. For companies in each of 79 different industries, the SASB has identified a specific set of “material” concerns along with metrics or KPIs that can be used to evaluate corporate performance in responding to those concerns. Perhaps the most important advantage of this approach is that, by limiting such reporting to material exposures (and so adhering to a principle that has long informed SEC requirements), the SASB guidelines should significantly increase the relevance and value to investors—while possibly holding down the costs—of the sustainability reports that large companies in the U.S. and abroad have been producing for decades. But, as the former SEC Chair also notes in closing, the adoption of such guidelines by companies should be viewed as just a first step toward improving disclosure. To help companies develop the most useful and cost‐effective disclosure practices, investors themselves will have to become more active in communicating their own demands and preferences for information. 相似文献
