KGHM market cap is diving

The share price of Poland's largest copper miner KGHM Polska Miedź was decreased by Erste from PLN 91.50 to PLN 69.20. Thus, the firm's market capitalization should drop by PLN 4 billion to PLN 14 billion , the media reported. The cheaper price of the miner's share is a result of the falling price of copper in the international markets. According to Tomasz Duda, an expert at Erste, it may continue to drop. Erste Group Bank AG (Erste Group) is one of the largest financial services providers in Central and Eastern Europe.
