Recent discussions from the White House have proposed a shift from quarterly to semi-annual earnings reports for companies. This suggestion raises a critical question for investors: does the financial burden of frequent reporting outweigh the benefits? Drawing on historical data from economist Robert Shiller, this article evaluates the significance of quarterly earnings reports and their potential impact on investment strategies.
The proposal for semi-annual reporting has sparked a debate among investors about the potential loss of crucial information.
While the prospect of saving resources may seem attractive to companies, the value of timely earnings data cannot be overlooked. This analysis aims to clarify whether quarterly earnings provide insights that are indispensable for both long-term allocators and short-term traders.

Understanding Quarterly Earnings and Their Relevance
Quarterly earnings reports, mandated by the Securities and Exchange Commission since 1970, serve as vital indicators of a company’s financial health. By examining Shiller’s data from January 1970 to June 2025, we can better understand the relationships between three-month earnings, six-month earnings, and overall earnings trends. The trend is assessed through a 61-month centered moving average to identify patterns over time.
The Impact on Long-Term Investors
Long-term investors typically seek to understand broader trends in earnings to make informed decisions regarding their portfolios. One way to measure the significance of quarterly earnings is to model changes in long-term earnings trends against three-month and six-month earnings data. By employing statistical methods, such as ordinary least squares regression analysis, the effectiveness of incorporating quarterly earnings data can be evaluated.
This analysis assumes that an investor possesses knowledge of half of the current trend in earnings. They have access to the first 30 months of earnings data within the 61-month window and can compare this with the last three or six months of earnings. The results indicate that including quarterly earnings data enhances the predictive capability of long-term earnings trends, with statistical measures reflecting improved model accuracy.
The Viewpoint of Short-Term Traders
While long-term investors benefit from a comprehensive understanding of earnings trends, short-term traders require more immediate insights. The frequent fluctuations in three-month earnings can significantly influence trading strategies. Empirical evidence suggests that changes in quarterly earnings closely correlate with subsequent short-term earnings variations, highlighting the importance of timely data for traders.
Statistical Evidence Supporting Quarterly Reports
Analyses of quarterly earnings changes reveal a persistent relationship, emphasizing the predictive nature of these reports. For instance, a model examining the correlation between past three-month earnings and future changes indicates a strong connection, with a significant R-squared value. This finding underscores the importance of quarterly earnings in informing trading decisions.
Furthermore, when assessing the relationship between six-month earnings and twelve-month forecasts, the inclusion of three-month earnings data markedly enhances model performance. The R-squared value increases significantly, demonstrating that more frequent earnings reports contribute to better predictive accuracy.
Evaluating the Trade-Offs
While the benefits of quarterly earnings reporting are evident, it is essential to consider the associated costs. Producing these reports entails financial expenditures for companies, which may lead to calls for reduced reporting frequency. However, regulators and stakeholders must weigh the potential savings against the risks posed by diminished transparency and reduced market efficiency.
In conclusion, the evidence suggests that quarterly earnings reports hold substantial value for both long-term and short-term investors. As the debate over reporting frequency continues, it is imperative that policymakers consider the implications of their decisions for companies and for investors seeking meaningful insights into market dynamics.
