Reddit Stock Pops on Long-Awaited S&P 500 Inclusion - Reddit (NYSE:RDDT)
S&P Dow Jones Indices said Reddit will replace AvalonBay Communities (AVB) in the S&P 500 effective before the Aug. 18 open. The change follows AVB’s merger of equals with Equity Residential (EQR), approved by shareholders with over 99% votes cast. AVB shares convert to 2.793 EQR shares; the combined firm rebrands as Vivmark Residential (VMRK) and keeps the S&P 500 spot. RDDT rose 11.03% to $175.56 in after-hours.
