Braskem is trading at BRL 4.81 (-9.93%) after UBS downgraded it to Sell.
- The downgrade came on September 16, citing persistent petrochemical spread pressures and restructuring challenges.
- UBS cut its local-share price target to BRL 3.75 from BRL 10.50.
- The downgrade is the clearest company-specific catalyst; broader markets are not showing a comparable selloff.
