MGLU3 shares plunged 58.19% on Monday afternoon, October 26, 2026, trading at R$ 5.30 around 2:17 PM (Brasília time). It is an atypical move that triggered a chain reaction across the retail and consumer sector on the Brazilian stock exchange.
Why are MGLU3 shares falling today?
MGLU3 shares are tumbling following the reelection of Luiz Inácio Lula da Silva and a sharp rise in future interest rates, which crossed the 16% mark on the long curve. According to analyses reported by outlets such as InfoMoney, Guia do Investidor, Seu Dinheiro, Times Brasil | CNBC, and Money Times, the election outcome triggered an abrupt repricing of market expectations, unwinding recent bets on monetary easing and pressuring companies dependent on credit.
There is no communication to the market or material fact from Magazine Luiza's management explaining today's plunge. All the liquidation observed on the screen stems from macroeconomic risk repricing and portfolio adjustments by large institutional investors.
It is worth noting that the trading session on 10/26 was still open at the time of this check (2:17 PM). Because prices fluctuate in real time, the closing price for the session may differ from the figure recorded in this article.

The stress was not restricted to Magazine Luiza: media outlets highlighted a generalized sell-off in retail and discretionary consumer stocks. Companies dependent on long-term financing and inventory turnover with high interest rates were hit the hardest.
