摘要: K线模式是股票短期投资中最常用的技术分析工具,但学术界却对K线模式的可盈利性存在争议。为了客观评价K线模式的可盈利性,提出从数据挖掘的角度出发,采用模式识别、模式聚类和模式知识挖掘的方法来对K线模式的盈利能力进行研究。为此,首先定义了K线序列的相似性匹配模型来解决K线模式的相似性匹配问题;然后,定义了K线序列的最近邻聚类算法来解决K线模式的聚类问题;最后,定义了K线模式盈利能力度量模型来对K线模式不同形态的利能力进行分析。实验采用近11年上证180指数成份股的数据作为测试数据集,对白三兵和黑三鸦这两个模式的盈利能力进行分析。实验结果表明:同一个K线模式的不同形态的盈利能力差别很大,有时甚至完全相反,这是K线模式可盈利性产生争议的一个主要原因。为了解决这一争议并提高基于K线模式的股票投资效果,亟需根据形态特征对现有的每一个K线模式做进一步分类,并提供更加严谨的模式定义。
