As the White House proposes a shift from quarterly to semi-annual earnings reporting, investors face a pivotal question: are the costs of producing earnings information justified by the returns? This inquiry is particularly relevant as financial transparency becomes increasingly critical in today’s market.
Utilizing historical data from economist Robert Shiller, this analysis investigates the correlation between quarterly earnings reports and their implications for both short-term traders and long-term investors.
The proposed change in reporting frequency raises concerns about the potential loss of valuable information that could influence investment decisions.

The Significance of Quarterly Earnings Data
Shiller’s extensive dataset covers the period from January 1970, when quarterly earnings reporting became mandatory under Securities and Exchange Commission regulations, to mid-2025. Analyzing this data allows for an examination of how earnings changes over three and six-month periods affect overall earnings trends.
To illustrate this, a chart can be referenced that shows three-month earnings in green, six-month earnings in red, and a longer-term trend in blue. While three-month earnings may appear more volatile, it is essential to assess whether these shorter intervals provide insights that enhance an investor’s ability to predict long-term trends.
Long-Term Implications for Investors
Long-term investors often aim to grasp the overall trend in earnings. A valuable method to evaluate the impact of quarterly earnings on trend prediction is through statistical modeling. By employing ordinary least squares regression, we can compare various models to determine which offers a better fit for estimating changes in trend earnings.
In our analysis, we assume an investor has access to 30 months of earnings data from the current 61-month window. The goal is to ascertain whether quarterly earnings data improves the predictive capacity for long-term trend changes. The results reveal that incorporating three-month earnings data significantly enhances the model’s accuracy, as evidenced by an increase in the adjusted R-squared value. This indicates that quarterly earnings can indeed inform long-term investment strategies.
Short-Term Trading Advantages
For short-term traders, the dynamics shift. The ability to swiftly react to changes in three-month earnings is critical for those looking to capitalize on market fluctuations. Empirical evidence suggests that changes in three-month earnings correlate with subsequent earnings shifts, indicating a persistent trend that traders can leverage.
For example, the correlation between past quarterly earnings changes and future shifts reveals a significant connection. This suggests that traders can benefit from the more detailed data provided by quarterly reports, which can inform rapid investment decisions.
Evaluating Regulatory Changes
As discussions about reducing the frequency of earnings reports intensify, it is vital to balance cost savings for companies against the potential loss of valuable information for investors. While greater frequency in reporting may incur costs, the insights derived from understanding short-term earnings changes could outweigh these expenses.
Historical surveys indicate that many industry professionals prefer maintaining quarterly earnings reports, underscoring the value they provide in promoting market transparency and informed decision-making. As regulatory bodies deliberate these changes, they must weigh the implications for both investor knowledge and market efficiency.
