Volatility measures and commodities added context to the trading backdrop. The CBOE Brazil Etf Volatility index, which tracks implied volatility on Bovespa options, climbed 3.27% to 28.13. In commodities, December Gold Futures rose 1.03% or 42.07 to $4,132.57 a troy ounce. By contrast, September crude oil fell 6.15% or 4.94 to $75.40 a barrel, while the December US coffee C contract gained 0.98% or 3.00 to trade at $307.70.

The session mixed strong single-stock rallies in steel and mining names with weakness in some consumer and industrial shares, and came alongside a rise in implied volatility and divergent commodity moves. Marcopolo's drop to a one-year low stood out among the declines, while several commodity-linked and retail names posted gains.
Overall, the market closed slightly lower with pockets of strength offset by sector pressure and higher measured volatility.
