The index reflects the development of the market capitalization for the most traded shares at the OM Stockholm Exchange's O-list. The Attract40-index follows the same rules and regulations as the SX-Generalindex and the weighting in the index is decided by the company's market capitalization. The companies in the index represent a market value of about 400 billion SEK.
Attract40 contains companies that the market has shown special interest for, during the past 6 months. The criterion the companies must reach are; that the turnover rate of the stock must be twice the turnover rate of the exchange as a whole, or that the average daily turnover is more than 16 million SEK and the market capitalization is more than 7 billion SEK. The free market capitalization must be more than 500 million SEK and market information must also be given in English.
