There are 2 that are far bigger than the others so I narrow it to these: http://www.spdrgoldshares.com/ (ticker symbol GLD) Since 12 nov 2004, named as "StreetTracks Gold Shares", in 2008 renamed to SPDR. Sponsored (= funded?) by the World Gold Council along the company World Gold Trust Services 2009/01/29 27,122,028 ounces 2011/01/18 41,795,939 ounces 2013/05/03 34,260,271 ounces 2014/01/02 25,547,853 ounces 2015/01/02 22,795,559 ounces http://us.ishares.com/product_info/fund/overview/IAU.htm (ticker symbol IAU) Since 21 jan 2005, originally by Barclays Global Investors, in dec 2009 sold to BlackRock 2012/11/29 11,390,402 ounces 2013/11/25 5,464,714 ounces 2015/01/02 5,182,164 ounces These two big gold market funds now exist a decade. Their gold stock trends clearly correlate with the gold price trend. The worlds annual traded gold is around 128,000,000 The worlds average annual central bank purchases/sales is around 13,000,000, with sales at low prices and purchases at high prices, so they can act as counterparties for these ETF's, from whoms shareholders try ofcourse the opposite. As aboves figures show: these ETF sold around half their stock since their peak. According to Thomson Reuters data, all ETF's together sold 880 tonnes in 2013, which was 1/3 of what they accumulated since they came into existence. Means that they had start 2014 2/3 left to sell. Since, SPDR sold a further 3 Moz with IShares mostly holding (sales < 1/10th of SPDR's sales). So, from todays onwards there is still a gold price hammer sized 2 times the one that came down over 2013-2014. 2012, golds peak average price year, was US$ 1669 per ounce. 2013 was US$1411 per ounce. 2014 was US$1266 per ounce. Their 2013 sales waved away US$ 258 of the average price. Another such sales would thus bring the average price down to around US$ $1000 And yet another such sales (the last of the 3/3 > 2/3 >1/3 > 0 would bring back US$ 750. Of course with all other things equal as 2013. Stockpiling, and destockpiling. Noone throws it in the ocean. When, depends on all of us boys and girls.
