MSCI Inc. stock closed in the mid-USD 550s on its US exchange on September 14, 2026, reflecting a decline of roughly 3.2% over the week as investor sentiment weakened around the name.

September 14, 2026 session in numbers
MSCI Inc. (ISIN US55354G1004, NYSE: MSCI) was quoted at about USD 554.61 in recent closing data for the week ending September 14, 2026, down roughly 3.21% from its prior level according to portfolio commentary from WVU SMIF. The same commentary noted that the stock weakened as investors focused on an elevated valuation and a higher operating-cost outlook following missed second-quarter revenue and earnings per share expectations, providing important context for the recent move. In the broader market backdrop, the S&P 500 closed at 7,619.98, down 0.5% on September 14, 2026, while the tech-heavy Nasdaq Composite finished at 26,333.04, up about 1%, according to data reported by Barchart and Zacks. This left MSCI Inc. underperforming the Nasdaq Composite over the recent period despite the broader index advance.
