美元上涨 COMEX黄金期货下跌0.2%
总结：美元上涨0.5%，各贵金属均顺势下跌，分析师认为，黄金市场对QE的反应比股市更敏感，而标普指数则相反。
纽约商品期货交易所（COMEX）12月黄金期货8月21日收盘下跌2.5美元，收报每盎司1,370.1美元，
电子盘最新报价续跌12.7美元，报1,357.4美元；
美元指数21日收盘上涨0.5%，
9月白银期货下跌0.5%，收报每盎司22.963美元。
纽约商业交易所（NYMEX）10月铂金期货下跌0.4%，收报每盎司1,519.1美元，
9月钯金期货下跌0.4%，收报每盎司746.9美元。
分析师认为，黄金市场对美国量化宽松政策的反应比股市更为敏感。
黄金价格现在已经回落至2010年11月美国宣布第二轮量化宽松政策前的水平。
标普500指数则相反，自2010年11月以来已经上涨接近40%。
分析师认为，近期贵金属相对股市表现优异，或同样表明黄金市场正从此前的过度计入价格中复苏过来。
