摘要: 以2005年7月21日至2010年10月29日的人民币兑美元汇率,人民币兑欧元汇率和人民币兑日元汇率三种汇率的每日中间报价为研究对象,利用R/S分析方法对其日收益率序列进行研究,结果表明,三个汇率市场不符合有效市场假设,具有明显的分形特征,并具有不同的循环区间长度。Abstract: Based on the central parity of RMB/USD, RMB/EUR and RMB/JPY from July 21, 2005 to October 29, 2010, R/S analysis is applied to the study of the daily return series.The conclusion indicates that the three exchange rates do not follow the Efficient Market Hypothesis, and they have clear fractal structures and different length of cycle.
