FACTBOX: Gold, silver exchange-traded funds (ETF) holdings

(Reuters) - Investment demand in precious metals exchange-traded funds (ETFs) remains robust as gold and other precious metals are trading at or near their record highs.

Changes in gold and silver ETF holdings are closely watched by market participants because sharp inflows in gold ETFs could be a bullish signal as it shows longer-term retail and institutional investors are entering the market.

ETFs are listed on the stock exchanges and offer investors exposure in the underlying commodity -- gold -- without taking physical delivery. Sponsors of such funds buy a matching amount of the commodity from the market to keep in bank vaults.

U.S.-based StreetTRACKS gold shares GLD.N is the world's largest gold ETF accounting for more than 80 percent of the metal held by all such funds, while iShares silver trust SLV.A is the top silver fund.
