MSG Rangers and Huron Consulting Group are set to join the S&P SmallCap 600, while Arbor Realty Trust and Supernus Pharmaceuticals will be removed. These changes signal significant index adjustments that city investors should monitor.

S&P Dow Jones Indices announced significant adjustments to the S&P SmallCap 600. Notable changes include the addition of MSG Rangers Inc., effective October 27, 2026, replacing Arbor Realty Trust.
