Sector Statistics Report

Data Collection Period

Data collected for fiscal quarters ending within the reporting period. Companies are matched by ticker symbol across time periods.

Growth Calculations

• Quarter-over-Quarter (QoQ): Compares current quarter to previous quarter (2-5 months prior for flexibility)
• Year-over-Year (YoY): Compares current quarter to same quarter last year (11-14 months prior)
• Outlier Handling: Growth rates are capped at -100% to +200% to prevent extreme outliers from skewing averages
• Minimum Revenue Threshold: Only companies with >$1M revenue in comparison period are included in growth calculations

Earnings Surprises

• Beat: Actual EPS > Estimated EPS
• Meet: Actual EPS = Estimated EPS
• Miss: Actual EPS < Estimated EPS

Price Reaction

Stock price percentage change following earnings announcement (typically measured as close-to-close or intraday swing).
