Lumen Stock Plunges 24% Amid AI Valuation Fears

In the week leading up to November 16, 2025, Lumen (NYSE: LUMN) stock saw a significant 24% decline in its share price. This sharp pullback occurred against the backdrop of a broader sell-off in the artificial intelligence (AI) sector, with the S&P 500 managing a modest 0.1% gain and the Nasdaq Composite declining by 0.5% over the same period.

Investors appear to have taken profit on Lumen stock amid growing concerns that AI-related valuations had become overheated. Following an impressive 50.5% rally in Lumen's share price so far this year, some investors opted to exit their positions and lock in their gains as the market faced an uncertain juncture.
