KLD 400 Index vs S&P 500

The KLD 400 index is one of oldest socially responsible investing (SRI) indices and it still offers SRI investors an alternative to traditional indices like the S&P 500. However some differences become apparent when examining the KLD 400 vs S&P 500 and we will explore these below.

A quick note that investors cannot invest directly in an index. These unmanaged indexes do not reflect management fees and transaction costs that are associated with an investable vehicle, such as the iShares MSCI KLD 400 Social ETF (symbol: DSI) or the iShares Core S&P 500 ETF (symbol: IVV). A reminder that these are simply examples as this site does NOT provide investment recommendations.

It is worth noting that the MSCI KLD 400 index is derived from the MSCI USA index. Our analysis of the MSCI USA Index vs S&P 500 found that the two are nearly identical. However, the KLD 400 contains some ESG screens that set it apart from both the MSCI USA and the S&P 500.

ESG Methodology

According to MSCI, the MSCI USA index is the parent index of the KLD 400. The first step in deriving the KLD index is to exclude any companies involved in Nuclear Power, Tobacco, Alcohol, Gambling, Military Weapons, Civilian Firearms, GMOs, or Adult Entertainment. Then constituents are added based on ESG considerations, as well as to keep sector and market cap exposures inline with the parent index. There is additional steps taken during the semi-annual reconstitution and rebalancing, all of which can be found on MSCI’s website.

Geography

Both the MSCI KLD 400 Index and the S&P 500 only include the stocks of US-domiciled companies.

Final Thoughts on KLD 400 vs S&P 500

Investors cannot invest in indices directly and should do their own research before deciding to invest in a fund that tracks either index. These indices are similar in many ways and performance differentials have depended on the time period being evaluated. Those considering benchmarking to the KLD 400 index (or any SRI/ESG for that matter) should first review the index methodology. The primary reason investors would use something like the KLD 400 index is to align their portfolio with their values, so they better ensure that they agree with the index methodology!

For instance, an investor may care deeply about the environment and social issues and be drawn to the KLD 400 index as a benchmark. However, if the investor is supportive of nuclear power as an alternative to fossil fuels, then the KLD index may not be the one for them.
