Smartfit is trading at BRL 22.50, up 4.02%, and no clear company-specific catalyst for the October 7 rise was identified. - On October 5, Smartfit agreed to invest up to R$32 million for as much as 20% of Buddha Spa, with an option to reach 30%. - Coverage linked the deal to the previous session’s sharp gain, not specifically today’s rise. - Broader markets are lower, so market context does not explain the move.
