Index changes also matter from an ETF and index fund flow point of view: FTSE 100, 250 and All Share trackers have to adjust to changes whenever they’re made.
Asset managers also have to buy and sell stocks to make sure they match the benchmark. And as the FTSE 100 is generally more liquid than other indices, inclusion in an index tends to boost flows into a particular stock. As more money moves into passive funds, index changes become more significant over time.
Greater liquidity means that buy and sell prices tend to be closer together (the bid-offer spread), meaning that it’s easier for investors big and small to enter and exit positions.
