Heath Jansen, 41, leads his Citi crew in London up one notch to second place, the position the firm most recently held in 1999. Monitoring 40 European metals and mining companies, the group of four analysts is applauded for its long-standing bearishness on U.K. copper miner Antofagasta. Deeming the stock overvalued at 1,118.86p in January 2012, they downgraded it from neutral to sell. Since then, Jansen and his colleagues have remained negative on Antofagasta. When the shares were on the rise last January, they reminded clients of the company’s unexpected cost increases and reiterated their negative stance. Sure enough, the stock began to decline again — and by the end of last month had settled to 650p, tumbling 20 percent over the trailing 12-month period and behind the regional broad market by 6.7 percentage points. “They stuck to their guns, and were right,” observes one ally. Also in January 2014, Jansen and his team highlighted their buy rating on the Channel Islands’ Petra Diamonds, at 118.20p, crediting the promise of two South African mines it had recently purchased from the De Beers Group of Cos. Shares of the diamond miner subsequently soared to 153.40p, through January 2015, and they remain recommended, with a price target of 257p.
