Brazil miner Vale loses $18bn in market cap after dam disaster
28 Jan 2019; AFP: Brazilian mining giant Vale lost more than $18 billion of its value Monday in a dramatic share plunge on the Sao Paulo stock exchange as investors reacted to the collapse of one of its dams that killed scores and left hundreds missing.
The 24.5 percent drop followed an eight percent dive on the New York Stock Exchange on Friday, the day the disaster occurred. The Brazilian bourse was closed that day for a public holiday.
