U is trading 6.1% up now at $48.58 after several strong sessions, extending a multi-day rebound from the mid-$40s. The significant upward movement appears driven primarily by stock-specific buying and momentum, as broader market indices remain mixed. * No major company-specific news, earnings, M&A, or analyst calls have been reported on tier-1 wires so far. * The current price action lacks a clearly identified headline catalyst, suggesting the move is driven by technical momentum rather than fundamental news.
