Vedanta, NALCO, Hindustan Zinc shares fall up to 3% as silver, aluminium, other metal prices tumble. Here's why

Shares of metal and mining companies fell up to 3 percent after silver, aluminium, copper and zinc prices tumbled to multi-month lows globally. The decline was driven by a stronger US dollar, easing West Asia geopolitical tensions leading to unwinding of risk premiums, and growing expectations of a hawkish Federal Reserve rate hike later this year. Silver alone plunged around 14 percent this week, trading at less than half its all-time high of about 121 dollars an ounce.
