The ongoing discussion regarding quarterly earnings reports has intensified, particularly following recent comments from the White House advocating for a shift to semi-annual reporting. This proposal raises significant concerns for investors about the potential loss of critical information that could influence their decision-making processes.
Utilizing historical data compiled by economist Robert Shiller, this article examines whether the frequency of earnings reports significantly impacts both long-term investors and those focused on short-term gains.
The central question remains: do the costs associated with more frequent earnings reports outweigh their benefits?

Analyzing the Benefits of Quarterly Earnings
In January 1970, the Securities and Exchange Commission (SEC) mandated quarterly reporting, establishing it as a cornerstone of financial markets. By analyzing the earnings data from Shiller’s database through mid-2025, we can investigate the relationships among various earnings reports and market trends.
Understanding Earnings Trends
To evaluate the implications of quarterly earnings on long-term investment strategies, we define the trend of earnings as a 61-month centered moving average. This analysis tests how variations in three-month earnings can aid investors in forecasting changes in the longer-term earnings trajectory. Through this perspective, we can identify the potential advantages of maintaining quarterly reporting.
When visualizing the data from 2000 to 2025, three-month earnings are represented in green, six-month earnings in red, and the longer-term trend in blue. Although three-month earnings exhibit greater volatility compared to six-month figures, their role in enhancing predictive accuracy for long-term investors remains ambiguous.
Implications for Various Investor Types
Conversely, short-term investors clearly benefit from the availability of quarterly earnings reports. The capacity to monitor earnings changes more frequently facilitates improved decision-making in dynamic markets. Empirical data corroborates this, indicating that traders can leverage this information effectively.
Long-Term Investment Strategies
For long-term investors, the significance of access to quarterly earnings becomes evident when assessing the predictive capabilities of these reports. Employing regression analysis, we can contrast the effectiveness of models utilizing three-month versus six-month earnings data in forecasting future earnings trends. The results indicate a marked improvement in predictive accuracy when quarterly earnings are included, affirming their substantial impact.
Specifically, adjusted R-squared values illustrate that incorporating three-month earnings changes into models enhances their fit, increasing from 0.098 to 0.126. Although this finding is modest, it underscores the importance of quarterly earnings in facilitating long-term investment forecasts.
Considering the Trade-Offs
While the potential advantages of quarterly earnings reporting are clear, it is crucial to acknowledge the associated costs. As policymakers consider reducing reporting frequency, they must balance financial savings against the potential erosion of transparency for investors. Transitioning to semi-annual reporting may diminish market efficiency, leaving investors with less timely information.
In conclusion, the analysis reveals that, despite the costs, quarterly earnings reports provide essential insights that enhance investment strategies for both short-term traders and long-term investors. As the debate over reporting frequency continues, understanding the implications of these changes will be vital for all market participants.
