Shares of Brazilian rice producer Camil (CAML3) tumbled 18.2% to close at R$4.41 on July 15, marking a sharp repricing of the stock following a dismal first-half earnings report.
The company reported a 57.6% year-on-year decline in net profit, which fell to just R$28 million for the period ending in June.
The collapse in profitability was driven primarily by depressed grain prices, which eroded margins across the harvest season.
The sell-off represents one of the steepest single-day declines for the stock in recent memory, reflecting investor frustration with the company's exposure to commodity price volatility.
While Camil is a dominant player in Brazil's rice market, its financial performance remains tightly coupled with global and domestic supply dynamics.
The sharp drop in earnings suggests that the company's cost structure may not be flexible enough to absorb sudden downturns in crop values.
