TAN is trading at $43.69, down 3.03% on September 24, 2026, as higher Treasury yields pressure long-duration growth and renewable-energy valuations. - The 10-year yield reached approximately 5.12%, its highest since 2007, after stronger-than-expected U.S. business activity revived inflation and interest-rate concerns. - All three major indexes—the S&P 500, Nasdaq Composite, and Dow Jones—were lower amid broader risk-off trading. - Solar weakness was driven primarily by macro rates and market-wide de-risking, rather than a clearly identified company-specific catalyst.
