Abstract: Neste trabalho, verificam-se evidências de que a diversificação e o valor das empresas são negativamente relacionados.

“…) Nonetheless, Lang and Stulz (1994) and Servaes (1996) have shown that the value of conglomerates may be discounted compared to firms that keep activities focused on their core business. In Brazil, the most recent study was conducted by Carvalho, Maia and Barbedo (2012). For the conventional wisdom, this decline happens because an increase in the number of segments generates agency problems and exacerbates the internal distortion of capital (Berger & Ofek, 1995;Shin & Stulz, 1998;Rajan, Servaes, & Zingales, 2000;Scharfstein & Stein, 2000).…”

“…Note that the contribution of this work is to investigate whether diversified firms are actually more leveraged than focused firms, not only considering periods of financial crisis but also analyzing in a systematic way, which would serve as a policy tool for business financing. Furthermore, we seek to add to discussions in the literature on the benefits of corporate diversification in Brazil, highlighting the effects of diversification on market value and corporate performance (Carvalho, Maia, & Barbedo, 2012) and addressing the possibilities generated by expanding the borrowing capacity of firms.…”

“…When such companies undergo expansion and increase in market share, they diversify their catalog of products and services to supply a more significant number of potential customers and thus ensure their growth. Offering more products implies creating or improving processes in order to maintain quality, productivity and ensure that, in the end, their consumers have a positive experience, consume again and recommend their products (Carvalho, Maia & Barbedo, 2012;Favretto, Roman & Sehnem, 2016;Palvölgyi & Moormann, 2021;Shukla, Swarnakar & Singh, 2021).…”
