MAC Solar Index Consultation Regarding Revised Index Methodology

MAC Solar Index Consultation Regarding Revised Index Methodology

Link to MAC-Solar-Index-Proposed-New-Index Methodology

March 11, 2021 – MAC Solar Index is conducting a consultation with market participants on a proposal to update the Index methodology, as seen in the attached document. There are a number of proposed changes, including but not limited to: (1) raising the minimum float-adjusted market cap for initial inclusion in the Index to $250 million from the current $150 million, (2) changing to a 3-month rather than 1-month minimum average daily average of $750,000 for initial inclusion in the Index, (3) imposing specified minimums for continued inclusion in the Index of $125 million of float-adjusted market cap and a 3-month average daily trading value of $375,000, and (4) implementing environmental and governance screens. We are also soliciting feedback on whether there should be any measures adopted that seek to limit ownership of the constituent stocks that are listed in any particular country or all countries allowed by the Index methodology.

For reference, the March 2021 quarterly Index review that takes effect after the close on March 19, 2021, will occur under the current methodology. Any changes in the Index methodology contemplated by this Index consultation will not take effect until some time after the March rebalance. See the current Index methodology at
