【摘要】 借用物理学领域中有关材料的塑性和弹性的理论,用类比推理方法研究股票价格变化中体现的塑性和弹性。弹簧在外力作用下的运动可类比地看成股价在成交量推动下的波动。股票的均衡价格是股票的买卖双方处于均衡态势时共同认可的价格,对应于弹簧在无外力作用时的平衡位置。股价塑性是指当股价偏离均衡价格且有一定的成交量和一定时间的作用下,股票的均衡价格产生移动的性质。股价弹性是指当股价偏离均衡价格且成交量萎缩的情况下,股票的价格会自动向均衡价格做恢复性移动的性质。更多还原

【Abstract】 This paper studies the plasticity and the elasticity of stock prices via analogical reasoning,with reference to material plasticity and elasticity in the field of physics.When stock prices fluctuate under the influence of volume,we can perceive this as movements of a spring caused by external force.The equilibrium stock price is determined by both the supply and the demand side,corresponding to the free position of a spring when all external force is removed.Stock-price-plasticity refers to the fact that when stock price deviates from its original price for a period of time and a certain volume is reached,then the stock price will shift to a new equilibrium position.Stock-price-elasticity refers to the fact that when deviation from its original price causes the volume to shrink,then the stock price will automatically restore to its original equilibrium position.更多还原
