Stock price when the opinion was issued
A lot of metals have been settling down, and Brazil's had some rough times. Might have broken the support level, probably because copper and metals are taking a breather. Possible it will see lows of 2020. Chart's more bearish than bullish right now.
He wouldn't buy it. If you already own, it's your call, as the next target is that 2020 low.
Depends on view of copper prices. Very high exposure to commodity swings. Good operator, but would advise a detailed investigation. Can be a risky asset and business.
