What now?
When a company is added to an index it can lead to an increase in demand for its shares from exchange traded funds that are designed to track an index and from fund managers that may have investment mandates which permit them to only buy shares on certain indices.
Conversely, when a share is removed it can lead to increased selling pressure as exchange traded funds dump them and fund managers are forced to sell them.
Though, given the (bleak) outlook for today's trade, it seems unlikely that this will have much impact on their relative performances.
