摘要:
股价的估值是一个困难的课题。股票交易中，股价、成交量、市值和买卖力度等高频交易数据构成了一个动态的变市值系统，在这个系统中，任何影响股价的因素最终都将转化为交易数据的定量变化，其中买卖力不对称直接引起股价波动从而导致市值变化。这个变市值系统的动态特性与变质量系统相似，可以用一个运动微分方程来描述，它的解表征了股票的“交易价值”。文中揭示了交易价值随交易数据变化，呈分时随机、阶段趋势特性，对股票的市场价格有支撑和牵引作用，从而为股票的估值提供了一种全新的分析途径。
Valuing of stocks price is a difficult topic for study. The high-frequency trading data such as the prices, the trading volumes, the market capitalization and the buying-selling dynamics at trading make up a dynamical system of variable market capitalization. Any factor that influences the stock prices will all be changed eventually into prices and volumes of buying in or selling out shares in the system, and the difference between the buying dynamics and the selling dynamics causes the fluctuation of the prices and results in changes of the market capitalization of the stocks. The momentum properties of the variable market capitalization system are described by a differential equation of the prices evolution. A new conception, trading value of the stocks that versus time and the trading data, is showed by the solution of the equation. The trading value reveals the properties that there are of both time-sharing randomness and stage tendency, and depicts a feature that there is fluctuation of the prices round the trading value at trading. So a new quantitative method for valuing of the stocks is advanced based on the trading value.
