Games Workshop Group Plc and Alliance Witan Plc, along with St James’s Place Plc, are set to join the FTSE 100 Index for the first time. This is due to their significant stock price increases, which have earned them blue-chip status. The index compiler FTSE Russell has announced that these companies will be added to the index after market close on December 20.

The inclusion of these new companies is expected to generate increased demand from tracker funds. This reflects their strong market performance and investor interest. The change in the index also involves the removal of Vistry Group Plc, Frasers Group Plc, and B&M European Value Retail SA.

With their addition to the FTSE 100 Index, Games Workshop Group Plc, Alliance Witan Plc, and St James’s Place Plc are poised to benefit from their newfound status as blue-chip companies.
