Linguagem e desempenho: duas pesquisas


Dois artigos interessantes. O primeiro estabelece uma relação entre legibilidade e custo do capital. Eis o abstract:

Using a large panel of U.S. public firms, we examine the relation between annual report readability and cost of equity capital. We hypothesize that complex textual reporting deters investors' ability to process and interpret annual reports, leading to higher information risk, and thus higher cost of equity financing. Consistent with our prediction, we find that greater textual complexity is associated with higher cost of equity capital. Our results are robust to a battery of sensitivity checks, including use of multiple estimation methods, alternative proxies of annual report readability and cost of equity capital measures, and potential endogeneity concerns. In addition, we hypothesize and test whether the nature of the relation between readability and cost of capital depends on the tone of 10-K filings. Our results show that the effect of annual report complexity on cost of equity is greater when disclosure tone is more negative or more ambiguous. We also find that the effect of annual report readability on cost of equity capital depends on the degree of stock market competition, level of institutional investors' ownership, and analyst coverage.

No mesmo periódico, um artigo que analisa a relação entre a linguagem positiva e o retorno do acionista. A conclusão é importante: que exagera na linguagem positiva não entrega resultado. Eis o abstract: 

We examine S&P 500 firms over 1999–2014 that characterize their annual performance with extreme positive language. Only 18% of such firms increase shareholder value, while over 80% have either negative or insignificant abnormal returns. Our evidence suggests that firms often base their claims of extreme positive performance on high raw returns or strong relative accounting performance. In comparison to firms that generate positive abnormal returns without boasting, our sample firms tend to have superior accounting performance. We conclude that boasting about performance is rarely associated with value creation and is more consistent with an emphasis on accounting metrics.
