According to @StockMKTNewz, the worst-performing S&P 500 stocks in 2025 include Trade Desk down 67.7%, Fiserv down 67.3%, Alexandria Real Estate down 49.8%, Deckers down 49.0%, Gartner down 47.9%, Lululemon down 45.7%, Dow down 41.7%, LyondellBasell down 41.7%, and Molina Healthcare down 40.4% (source: @StockMKTNewz). The scale of these declines spans roughly 40% to nearly 68%, which the source characterizes as the official worst performers list for 2025 (source: @StockMKTNewz). Periods of equity stress have historically coincided with higher short-term correlations between crypto and stocks, so BTC and ETH traders may monitor cross-asset flows as S&P 500 laggards capitulate (source: IMF Global Financial Stability Note Jan 2022; BIS Bulletin 2022 No. 52).
