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.
Base metal investing, in general, is very cyclical. Very rarely a long-term growth story that you buy and hold because you always want to be there. That applies to base metals and precious metals. They can go through months or even years where they're doing great, and then they'll be out of favour for months or years. When the global economy's slowing, these things cheapen up quite a bit. And if we go into recession, they'll cheapen up even more.
He's been buying for his portfolio. Already at the low end of the range, though could get cheaper if we hit a recession.
