Insights
S&P DJI raised market cap thresholds for its indices, reflecting market growth and potentially impacting index fund flows and company valuations.
S&P Dow Jones Indices has increased the market capitalization thresholds for additions to its widely tracked S&P Composite 1500 indices. The S&P 500 minimum threshold rises

This recalibration has several implications. Companies near previous thresholds that haven't crossed the new boundaries may experience delayed index inclusion. Conversely, companies that have grown past the old thresholds but below the new ones might face unexpected non-inclusion. Additionally, companies currently in indices that fall below these new thresholds won't be automatically removed, as these criteria only apply to new additions.

- S&P MidCap 400 index 鈥� 85th-93rd percentile
- S&P SmallCap 600 index 鈥� 93rd-99th percentile
Companies passing the total company-level market capitalization criteria must also have a security level float-adjusted market capitalization (FMC) that is at least
As a reminder, the market capitalization eligibility criteria are for additions to an index, not for continued membership. As a result, an index constituent that appears to violate criteria for addition to that index is not removed unless ongoing conditions warrant an index change.
