Why Do Individual Investors Disregard Accounting Information? The Roles of Information Awareness and Acquisition Costs

We investigate the frictions that impede individual investors’ use of accounting information and, in particular, their costs of monitoring and acquiring accounting disclosures. We do so using an archival setting in which individuals are presented with automated media articles that report both current earnings news and past stock returns. Although these investors have earnings information readily available, we find no evidence that their trades incorporate it. Instead we find that their trading responds to the trailing stock returns presented in the articles. Our study raises questions about the efficacy of regulations that aim to aid less sophisticated investors by increasing their awareness of and access to accounting information.     

The Textual Contents of Media Reports of Information Security Breaches and Profitable Short-Term Investment Opportunities

Information security-related incidents continue to make headlines. Interestingly, researchers have found mixed results when attempting to associate reports of information security breaches with changes in the affected firm's stock price. This research delves further into this puzzle by investigating the association between the textual contents of information security breach media reports and the stock price, as well as the trading volume reactions of the affected firm(s) around the breach announcement day. Our findings suggest that when the textual contents of breach reports provide more detailed information regarding the incidents, a more consistent belief is formed by the market about the negative impact of the reported security incident on the firm's business value. However, when there is a lack of specific information regarding the reported breach, the market does not seem to reach consensus on the impact of reported security incidents. We further demonstrate that different perceptions exist among general and sophisticated investors regarding the impact of reported information security incidents on a firm's future performance as demonstrated by changes in trading volume. By exploiting the different perceptions among investors, we form a trading strategy to demonstrate that, on average, one can make about 300% annual profit around the breach announcement day.     

Impact of algorithmic trading on speed of adjustment to new information: Evidence from interest rate derivatives

In February 2012, the Australian Securities Exchange introduced co-location services for futures traders, thus providing a natural experiment to test the impact of algorithmic trading (AT) on the speed of adjustment and price discovery during scheduled macroeconomic releases. Our results demonstrate that, in the presence of AT, the speed of adjustment to new information has improved for both exchange-traded futures and over-the-counter-traded swaps. In addition, we find that the price discovery contribution of the futures market improves in the post-AT period, with this improvement significant for macroeconomic announcement days.     

When Good News Is Not So Good: Economy‐wide Uncertainty and Stock Returns

This paper shows that variation in economy‐wide uncertainty causes asymmetric stock price responses to firm earnings surprises. The uncertainty that attends bad earnings news that arrives during expansions with greater economy‐wide uncertainty occasions larger price declines. This is because news inconsistent with investors’ prior beliefs about the state of the economy increases uncertainty, which amplifies the negative cash flow effects contained in bad earnings news. Asymmetrically, the positive cash flow effect of good earnings news that arrives during recessions is offset by increased investor uncertainty, which results in relatively smaller price reactions to the good news. This is consistent with Veronesi's rational expectations equilibrium model, which shows that investors demand higher expected returns in the face of greater uncertainty.     

Do Analysts Disclose Cash Flow Forecasts with Earnings Estimates when Earnings Quality is Low?

Cash flows are incrementally useful to earnings in security valuation mainly when earnings quality is low. This suggests that when earnings quality decreases, analysts will be more likely to supplement their earnings forecasts with cash flow estimates. Contrary to this prediction, we find that analysts do not disclose cash flow forecasts when the quality of earnings is low. This is because cash flow forecast accuracy depends on the accuracy of the accrual estimates and the precision of accrual forecasts decreases for firms with low quality earnings. Consequently, as earnings quality decreases, cash flow forecasts become increasingly inaccurate compared to earnings estimates. Cash flow estimates that lack reliability are not useful to investors and, consequently, unlikely to be reported by analysts. This result provides an explanation for why analysts are less likely to report cash flow estimates when earnings quality is low.     

The impact of economic news on bond prices: Evidence from the MTS platform

Although there is an extensive literature on the impact of macroeconomic announcements on asset prices, the bond market has received less attention than the foreign exchange and equity markets, even less if we consider the European market. This paper uses high-frequency intra-day data over a three-year period to investigate the impact of regularly scheduled macroeconomic news and monetary policy announcements on the returns of the Italian government bond market, the largest one in the Euro-zone. With respect to the previous papers, we use a much broader set of announcements, 68, and a relatively novel dataset (MTS). We find that 25 news have a significant impact on bond returns and that almost all announcements are incorporated into prices within 20 min from the release.     

政府审计、内部控制能有效提升组织韧性吗？

基于“免疫系统论”、组织韧性模型,以内外部协同治理为视角,分析政府审计、内部控制促进组织韧性提升的机理,进而以2010—2018年被出具政府审计报告的央企控股的沪深A股上市公司为样本,采用政府审计公告冲击下的股价波动来计量组织韧性,研究政府审计、内部控制与组织韧性之间的关系。结果表明：高强度政府审计及高质量内部控制都能有效促进组织韧性提升,政府审计与内部控制在促进组织韧性提升上具有明显的协同作用;进一步研究发现,在政府审计结果公告揭示的问题中,执行国家经济政策方面以及企业重大经营决策和内部管理方面存在问题的揭示对组织韧性的提升作用明显。     

Informed trading around earnings announcements—Spot,futures, or options?

Recent literature reports higher single stock options (SSO) volume before earnings announcements (EA). There are no studies that explore single stock futures (SSF) in this context because of illiquid SSF markets in developed countries. Similar to SSO, SSF provide embedded leverage and facilitate short selling although at a lower cost, but do not provide downside-risk protection. India’s liquid SSO and SSF provide a unique setting to study the preference of informed traders. We observe an increase in both SSO and SSF volume before EA. Further, SSF dominate SSO possibly due to SSO becoming expensive before EA and higher information leakage in India.     

Firm Size and the Information Content of Annual Earnings Announcements: Australian Evidence

Abstract:   We investigate the effect of firm size on the market's short‐window response to annual earnings announcements for a large sample of Australian listed companies. Our research design involves regressions of unexpected earnings against unexpected returns. Non‐linearity in the returns‐earnings relationship is incorporated and other factors known to affect the response to earnings announcements are controlled for. Contrary to prior US research, our results show that firm size has either no effect on the response to earnings announcements (3 day window) or the response is significantly stronger for larger firms (twenty‐one day window). The information content of earnings announcements is present across firm size categories but the nature of the response differs with firm size and context.     

Trading around macroeconomic announcements: Are all traders created equal?

This paper examines the effects of macroeconomic announcements on equity index markets using high frequency transactions data for the regular and E-mini S&P 500 index futures contracts. For ten types of announcements that significantly affect prices, we analyze the price adjustment process and the trading patterns of exchange locals and off-exchange customers around the announcements. We find a large increase in trading activity immediately after the announcement. The results also show that during this initial surge in trading activity, locals are able to time their trades better than off-exchange traders even when locals do not have the advantage of access to the order flow. The trading strategy followed by exchange locals in the first 20 seconds after the announcement tends to be profitable, while off-exchange traders tend to make losing trades over the same time period. These results lend evidence that local traders tend to react to the macroeconomic information faster than off-exchange traders.
