I don’t think they carry enough cash on their books and they’ve got a bit too much debt for an averaging down.
But…it’s got a number of things likely going for it: 1) commodities are starting to boom again. 2) Brazil is a commodity country that will likely benefit from that commodity boom. 3) it’s in a sector that’s needed: electricity. 4) it’s long-term Elliott Wave counts look favorable for overall upside.
So I’d just hold what you’ve got and only invest additional captal (for averaging down) in the most sound companies that you hold, fundamentally.
