The aim of this study is to examine the dividend policy behavior of firms listed at Stockholm Stock Exchange from 2005-2011. We examine the behavior from a Market Cap (firm size) and industry classification (group characteristics) perspective due to the structure of Stockholm Stock Exchange, by using non-parametric methods and Lintner`s model. The conclusions are as follows: (i) Market Cap listing and industry classification matters for the propensity to pay dividends and we observe that firms in Mid Cap and Small Cap were more likely to pay dividends in 2011 than in 2005. (ii) Neither Market Cap listing nor industry classification affects the firms’ payout ratio. (iii) Market Cap listing affects the firms´ level of paid DPS (dividend per share) but not significantly when we compared firms in Large Cap to firms in Mid Cap. Industry classification affects the firms´ level of paid DPS. (iv) Current EPS (earnings per share) and past DPS are important factors for deciding current DPS when firms were classified into Market Caps, but not for all firms when they were classified into industries. (v) Firms follow regular but unstable dividend policies despite Market Cap listing. Firms in the Health Care industry follow irregular and unstable dividend policies while the firms in the other industries follow regular but unstable dividend policies.
