About Xcel Energy Inc. (XEL) Earnings

This page provides Xcel Energy Inc. (XEL) earnings call transcripts from SEC 8-K filings along with AI-powered predictions for post-earnings price movements. Our machine learning models analyze historical earnings data, pre-earnings price patterns, volume changes, and volatility to predict 1-day, 5-day, and 20-day returns after each earnings release.

Earnings transcripts are sourced directly from SEC EDGAR filings. Predictions are generated using gradient boosting models trained on XEL's historical earnings reactions. All predicted returns are shown as percentages, and predicted prices are calculated from the closing price at the time of prediction. Past performance does not guarantee future results.
