简介:在伊朗核问题恶化,美元持续走弱与全球商品市场特别是基础金属价格全线飘红、屡创新高的形势下,国际黄金价格五月上旬再度强势上扬,现货黄金创730.65美元的新高,虽然在基金的获利回吐盘的打压下,价格在五月末快速回落,但是其长期的上涨趋势仍然保持良好。金价的加速上扬是此轮行情的最显著特征,回顾黄金价格的涨势来看,从国际黄金市场进入牛市以来,价格从低位260美元涨到460美元间隔大约三年半的时间;价格从460美元到660美元只用了6个月的时间,而从660美元到今年的高点730.65美元仅用了一周的时间。从价格的横向比较来看,虽然黄金价格的逊色于原油、铜等品种,但是其波动率还是远远高于道琼斯指数。
