Dull aluminium market on the London Metals Exchange (LME) has taken a toll on the stocks prices of major domestic firms. While Hindalco Industries has found itself at the receiving end, Nalco has held ground because of the impending disinvestment. Hindalco stock has lost around 48 per cent of its value from Rs 820 on February 2002 to Rs 460 on October 14, 2002. Nalco stocks, although considered to be as efficient an aluminium producer as Hindalco, have faired comparatively well on the Stock Exchange, Mumbai (BSE). Nalco stocks, which were ruling at Rs 78 in February 2002 rose by 50 per cent on the BSE to Rs 117 in July.
