About the ESG Equity Indices
The SIX ESG Equity Indices provide an avenue for investing in Swiss equities issued by companies with a well-established and standardized sustainability profile. By doing so, SIX facilitates the advancement of sustainably operating companies, contributing to a long-term, more sustainable trajectory for the Swiss economy.
In response to the growing trend toward sustainable investments, SIX has introduced these indices to meet market demand. Companies included in the SIX ESG Equity Indices undergo evaluation based on specific ethical, social, and measurable corporate governance criteria. These criteria encompass all relevant business activities. As a result, these indices offer a consistent framework for investing in Swiss equities aligned with ESG principles.

The SPI ESG and SPI ESG Weighted Indices share the same selection process, determined by the index methodology. Consequently, both indices include identical components, featuring companies that demonstrate a high level of sustainability commitment.
The SPI ESG Index evaluates Swiss equities based on ESG Ratings provided by Inrate. It comprises components from the Swiss Performance Index (SPI) that achieve at least a C+ rating on a scale from A+ to D- and fulfill certain revenue thresholds in controversial sectors. Additionally, index candidates have to meet the minimum standards set by the OECD Guidelines for Multinational Enterprises, must meet the United Nations Global Compact (UNGC) assessment criteria and avoid being listed on the Swiss Association for Responsible Investments (SVVK) exclusion list. Weighting is based on free-float market capitalization.
The SPI ESG is reviewed once a year in September. Its calculation takes place every three minutes. The index was published for the first time on 1 February 2021 and has been calculated since 1 July 2010, when it was standardized at 100 points.
The SPI ESG Weighted Index assesses the performance of Swiss equities based on ESG Ratings provided by Inrate. Unlike the SPI ESG Index, which solely relies on free-float market capitalization for weighting, the SPI ESG Weighted Index adjusts component weights based on their ESG Rating.
The adjustment factor is directly linked to the rating. Components with a C+ rating are halved in weight, while those with the highest rating are doubled. Intermediate components receive a capping factor, linearly derived between 0.5 and 2.
The SPI ESG Weighted is reviewed once a year in September. Its calculation takes place every three minutes. The index was published for the first time on 1 February 2021 and has been calculated since 1 July 2010, when it was standardized at 100 points.
The SPI ESG Size Indices track the performance of large, mid, and small Swiss equities based on ESG Ratings provided by Inrate. These indices include components from the SPI Large, Mid, or Small, which are part of the broader SPI ESG universe. Component weights are determined by their free-float market capitalization. The SPI ESG Size Indices are calculated in three versions: total return, net return, and price return.
Additionally, we have the SPI ESG Extra and the SPI ESG ex SLI Indices, both assessing the development of small and mid Swiss equities based on ESG Ratings from Inrate. The SPI ESG Extra comprises SPI Extra components from the SPI ESG, while the SPI ESG ex SLI includes SPI ex SLI components, which are part of the SPI ESG.
The SPI ESG Size Indices are reviewed once a year in September. Their calculation takes place every three mintues. The indices were published for the first time on 3 May 2023 and have been calculated since 1 July 2010, when they were standardized at 100 points
The SPI ESG Select Index tracks the performance of Swiss equities based on ESG Ratings provided by Inrate. The SPI ESG Select Index is derived from the the SPI ESG Index. During the index review, which takes place once a year in September, components are selected based on their ESG Impact Rating and market capitalization, until the index comprises half the number of components in the broader SPI Index.
To mitigate cluster risks, the index actively manages component weights. A UCITS capping mechanism ensures that no two components exceed a weight of 20%. The review of the capping factors is carried out four times a year in March, June, September and December.
The SPI ESG Select Index are calculated end-of-day. The index was published for the first time on 29 March 2021 and has been calculated since 1 July 2010, when it was standardized at 100 points.
The SXI Switzerland Sustainability 25 Index tracks the performance of Swiss companies deemed sustainable based on Inrate’s ESG Rating. This index is constructed from the SMI Expanded and consists of a fixed set of 25 components, subject to annual review in September. Component weights are determined by their free-float market capitalization and capped at 15% (reviewed quarterly in March, June, September and December).
The SXI Switzerland Sustainability 25 Index is calculated in three versions being total return, net return and price return and its calculation takes place every 3 minutes. SIX also calculates a decrement version of the index. The SXI Switzerland Sustainability 25 was published for the first time on 17 June 2014 and was standardized at 100 points on 30 December 2008.

Index Dependencies
An index is created by applying its selection criteria to an index universe. Because the index universe is often a different index, the index composition depends not only on the selection criteria of the index itself, but also on the selection criteria of its index universe. The resulting index dependencies are shown in the following overview:
