Introduced in 2003, S&P Equal Weight Index (S&P EWI) is the equal-weight version of the widely regarded S&P 500. The index has the same constituents as the capitalization weighted S&P 500, but each company in the S&P EWI is allocated a fixed weight.

Index constituents exhibit the following characteristics:

• Underlying Indices – S&P 500
• Weighting – Attribute weighted: Equal weight of 0.20%
• Rebalancing – Quarterly; Coincide with S&P 500 share adjustments

S&P EWI is designed to meet the need for benchmarking, investing and trading strategies that require a size-neutral index compatible with the S&P 500. S&P EWI provides an even spread of individual stocks and offers different sector exposures than the S&P 500.

Index Governance and Policy
This index is maintained by the S&P Index Committee, whose members include Standard & Poor's economists and index analysts. It follows a set of published guidelines and policies that provide the transparent methodologies used to maintain the index.
