MUMBAI, Nov 25 (Reuters) - Indian gold futures opened weak on Tuesday on a strong rupee and weak overseas markets, but investment demand helped the market to move into positive terrain, analysts said. "A strong rupee is pulling down the market," said Subodh Gupta, an analyst with Anand Rathi Commodities. The rupee rose to its strongest in almost a week on Tuesday, supported by higher stock markets and a weaker dollar overseas. India, the world's largest gold consumer, imports most of its requirement. A strong rupee makes imports cheaper. Overseas gold dropped more than 1 pct on Tuesday as the dollar gained against the euro and as investors booked profits after pushing bullion to its highest in almost six weeks on turmoil in financial markets. However, investment demand may cap the losses, said Kunal Shah, an analyst with Nirmal Bang Commodities Pvt Ltd. Gold has rallied since a crisis struck global financial institutions, diverting funds away from stocks as investors turned to the safe-haven appeal of the yellow metal. In macro-economic reports, traders will be closely watching U.S. Q3 preliminary GDP data along with currency markets for further direction, analysts said. Open interest for December gold on MCX was at 10,175 lots, down from 10,269 the previous session. Volume on Monday was 61 kg.
