摘要(Abstract):
市场相对估值比率是衡量股票价格相对于股利、盈利和账面价值水平的重要指标,其预测能力关系到估值信号在投资决策和市场监测中的应用价值。选取具有A股大盘股代表性的沪深300指数为样本,基于2005年第二季度至2025年第四季度数据,采用HP滤波法将股利价格比(DP)、盈利价格比(EP)和账面市值比(BP)这三类相对估值比率分解为周期成分和趋势成分,并探究其价格预测能力。研究发现:双边HP分解下,周期成分与趋势变化对未来收益的作用方向相反,两类信息在原始比率中相互削弱;DP、EP周期成分分别负向预测股利和盈利增长,BP趋势变化正向预测短中期账面资本盈利能力。递归单边HP检验进一步表明,中长期正向收益信息主要集中于周期成分,并支持BP趋势变化的基本面预测关系。
