Why is Gerdau stock sliding today?

Gerdau SA Pref (GGBR4) stock fell 5.2% to R$22.94 after Itaú BBA downgraded it to Market Perform, citing cooling steel market conditions and limited upside. Insider selling and sector-wide pressures from Chinese imports also contributed to the decline, with the stock trading near R$22-23, a range seen as more balanced by analysts.
