RGNX
September 21, 2025
S&P Dow Jones Indices announced on December 6, 2024, that REGENXBIO Inc. (RGNX) will be removed from the S&P SmallCap 600 index. This change is effective prior to the open of trading on Monday, December 23, 2024. The removal is part of the quarterly rebalance to ensure each index is more representative of its market capitalization range. REGENXBIO was deemed no longer representative of the small-cap market space. Index deletions can result in institutional investors, particularly passive index funds, selling their shares to rebalance their portfolios, which can exert downward pressure on the stock.
