Strategic Use of Volume of Financial Items in 10-K Reports
研究发现企业通过减少年报中财务项目的数量来掩盖未来业绩不佳，投资者对此反应滞后，导致股价暂时高估。
We investigate whether firms limit the volume of financial items in annual reports (including the financial statements and footnotes) to obfuscate poor future firm performance, and how investors react to this reduced volume. We estimate abnormal volume to capture managers’ discretion over reporting in the 10-K and find that abnormally low volume predicts poor future earnings. This relation is more pronounced in firms where the market has difficulty in detecting managerial intervention in the disclosure process. We also find that abnormally low volume predicts negative future returns, suggesting that managers benefit from disclosing fewer financial items by delaying the incorporation of bad news into stock prices. Further corroborating our results, we find that the volume is abnormally low when there exist strong managerial incentives to withhold bad news and manipulate investor perceptions upward. Overall, our evidence is consistent with the notion that managers attempt to obfuscate poor future performance and inflate current stock prices by disclosing fewer financial items in the 10-K.
