About the market cap segments

Companies belong to a market cap segment (Small-, Mid- and Large Cap) based on its average market value during the given review month. Each segment is reviewed annually based on the average market cap in November with adjustments taking effect in January the following year. The market cap calculations are based on the total number of shares, i.e. both listed and non-listed shares, of a company. Companies with a market value exceeding EUR 1 billion are in the group of “Large Cap”, while companies with a market value smaller than EUR 150 million belong to “Small Cap”. Companies with a market value between EUR 150 billion and EUR 1 billion belong to the “Mid Cap” segment.
