I had written about the best way to invest in gold in India looking at the different ways of buying physical gold and gold etfs.There was also the option of investing in gold mutual fund which invest in gold mining companies as well as looking at whether to buy gold from banks or you were better off buying gold from your neighbourhood jeweller.Alll the options of buying gold have their advantages and disadvantages.Gold ETFs have become the fastest growing segment of buying gold in India with most people prefering teh convenience and ease of buying gold the demat way.Note only does it have the security and storage advantages,it is also easily saleable without a huge transaction costs.Its no wonder that most asset management companies in India have launched gold etf products to take advantage of the growing trend of buying gold Etfs in India.SBI and UTI,two of the oldest government owned mutual fund houses in the country too have started gold etfs besides the private companies.Benchmark Gold Bees remains the oldest gold etf in the country and is looking to gain marketshare after Goldman Sachs bougth the company.IDBI has joined the gold etf party becoming the latest AMC to start a gold ETF.There is little to distinguish these Gold ETFs from each other since they don't have any active management and are mostly linked to the price of gold.The best gold etf is the one which has the least tracking error and the lowest expense ratio.I don't have a favorable opinion of the mutual fund etfs in India since they charge very highly and there is lack of variety and liqudity in the Indian ETF market.
