What Moves Index Prices?

Index prices are determined by the price changes of their components. This means there’s a strong correlation between the index’s performance and the prices of the main constituent stocks. Some of the factors capable of moving index prices include:

  • Overall Market Sentiment: The structure of indices allows them to serve as stock market benchmarks. Because they are composed of multiple stocks, they tend to reflect the overall sentiment in the market. So, for instance, if the market is generally bullish, an underlying index will tend to see its prices rise. Some of the factors that can influence market sentiment include: Economic factors such as wages and inflation, Company news reports, Central bank announcements and Interest rates

  • Company News: News about companies with significant weighting within an index can influence its overall price direction. Some of the most impactful company news include: Earnings reports, Profit forecasts and warnings, Mergers and acquisitions and Changes in management.

  • Index Rebalancing: Most indices are rebalanced periodically. This rebalancing can see new companies included in the index while others are dropped. This rebalancing may also include an increase or decrease in the weightings of certain components within the index. The period from pre-announcement to effective rebalancing date and post-rebalancing period can be very volatile for prices of indices depending on the expected events.

  • Sector Performance: The performance of a sector can influence the overall performance of an index. For instance, Technology has a sector weight of about 27% on the S&P 500. If the sector faces tough economic conditions and tech stock prices decline sharply, this will also trigger price losses on the S&P 500.

  • Commodity Prices: Commodities support many economic activities of various companies. Many indices include the stocks of commodity companies. For instance, the UK FTSE 100 has about 13% of its weight in energy. Therefore, changes in the commodity market can have an influence on the overall price of the index.

  • Political Events: As broad benchmarks, indices are vulnerable to major political events such as elections, trade wars, or cross-country conflicts. For instance, the UK Brexit event triggered volatility in the UK indices market.
