“…Regarding the control variables in the estimation with fixed effects, the results are similar to those previously found. Adding that the leverage was shown to have a negative effect on the company's value, that is, the increase in indebtedness decreases the companies' market value, which differs from previous studies that show that leverage has a disciplinary effect on the performance and market value of companies (Araújo et al, 2018;Moura et al, 2020), and liquidity had a positive effect, which denotes that the solvency of the entities is capable of reflecting positively on the market value of the companies (Arrighetti et al, 2014;Moura et al, 2020).…”
