Recent discussions within the financial sector have highlighted a contentious issue: the frequency of earnings reporting. The White House has proposed transitioning from quarterly to semi-annual earnings reports, prompting investors to question whether this change could result in a loss of essential information. The central inquiry is whether the benefits of more frequent reporting outweigh the associated costs.
To explore this matter, we can reference the extensive analysis conducted by economist Robert Shiller.
He compiled data dating back to January 1970, the year when the Securities and Exchange Commission (SEC) mandated quarterly earnings disclosures. This historical data allows for a thorough examination of the relationship between three-month and six-month earnings and the overall trend in earnings. Such insights are valuable for both short-term traders and long-term investors.

Understanding the Data: Quarterly vs. Semi-Annual Reporting
In assessing the potential impacts of less frequent reporting, it is crucial to understand how earnings data can inform investor decisions. Shiller’s data extends from 1970 to 2025, providing a comprehensive view of how earnings fluctuations can impact investment strategies. By analyzing the trends in three-month earnings, six-month earnings, and the overall earnings trajectory, we can determine whether quarterly data significantly contributes to forecasting longer-term trends.
Assessing Long-Term Investors’ Needs
For long-term investors, who prioritize sustained growth and market trends, a grasp of short-term earnings changes could enhance predictive capabilities. To quantify this, I employed a statistical approach comparing models utilizing six-month earnings against those incorporating both three-month and six-month earnings. The goal was to ascertain if including quarterly earnings yields a more accurate forecast of long-term earnings trends.
The preliminary results suggest that while three-month earnings can exhibit greater volatility, their inclusion in predictive models improves overall accuracy in trend forecasts. Specifically, the adjusted R-squared value, which measures the proportion of variance explained by the model, increased significantly when incorporating three-month earnings data. This indicates that quarterly earnings may provide valuable insights for investors navigating market complexities.
The Perspective of Short-Term Traders
In addition to long-term investors, short-term traders can benefit from frequent earnings reports. These investors typically respond to rapid market changes, making the immediate data from quarterly reports crucial to their strategies. Historical data reveals that short-term earnings fluctuations often correlate with subsequent market movements, underscoring the importance of timely information.
Data Patterns in Quarterly Earnings
The autocorrelation in quarterly earnings changes illustrates a persistent relationship within earnings trends. For instance, evaluating how three-month earnings changes relate to future three-month changes reveals a significant correlation. This persistent relationship enables short-term traders to leverage quarterly data for informed decision-making.
Moreover, when examining how six-month earnings data influences twelve-month earnings forecasts, it becomes evident that including three-month earnings enhances predictive accuracy. The R-squared values indicate a notable improvement, reinforcing the notion that quarterly earnings reports deliver critical insights for traders seeking opportunities in fluctuating markets.
The Broader Implications for Investors
As regulators contemplate adjustments to the reporting frequency, it is vital to consider not only the potential cost savings for companies but also the broader ramifications for investors and the economy. The loss of transparency resulting from less frequent reporting may impair investors’ ability to make informed decisions, ultimately affecting market efficiency.
Historically, surveys among investment professionals reveal a strong preference for quarterly earnings disclosures, reflecting a collective recognition of their significance. Evidence suggests that while generating these reports incurs costs, the wealth of information they provide is invaluable for maintaining informed market strategies.
