# Divergence in Earnings Forecasts Across Major Data Providers Significant variations found in earnings estimates among top five financial data providers. - **Source:** [Journal of Accounting Research](https://onlinelibrary.wiley.com/journal/1475679x) - **Published:** 2026-06-18 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/bc1c7390-8379-4363-9e7e-c2d2f675771f ## Discrepancies Among Data Providers Substantial differences exist in both forecasted and actual street earnings values produced by the five major financial data providers (Bloomberg, Capital IQ, FactSet, I/B/E/S, and Zacks) for the same firm-quarters. These variations suggest market participants may act on divergent information sources. ## Impact on Market Reactions Earnings surprises calculated differently by data providers have economically meaningful effects on price responsiveness and liquidity around announcements. Investors tend to align with higher-quality data sources when expectations are missed. ## Quality Differential Matters The research demonstrates that quality differences among providers influence investor decisions. I/B/E/S particularly stands out in quality metrics, justifying its use as a reference point in academic studies. ## Divergent Information Strategies Providers' differentiated information production strategies can create capital market frictions. These strategic differences lead to inconsistencies in evaluating corporate financial performance. ## Investor Behavior Patterns When providers disagree on whether earnings met expectations, investors typically side with higher-quality sources. However, price reactions don't fully incorporate these quality differentials during announcement windows. ## Implications for Market Efficiency The findings highlight the need for standardized data production processes to reduce information asymmetry. Improving data quality is crucial for enabling more consistent investment decisions across market participants. ## Sources covering this story - https://onlinelibrary.wiley.com/doi/10.1111/1475-679x.70072?af=R — --- _Summary written by Brifing from the original reporting.
