Idea

At a given specific time point, market value explanition models think market values of listed firms can be explained by theirs financial informations and market factors.
Under such assumptions, these models will induce an intrinsic market value of a listed firms at a specific time, however, there's always a residue term, which is also the difference between intrinsic value and current market value.
We name this residue term as Idiosyncratic Market Value Factor (IMVF), larger this factor is, indicating more upper bias is between current firm value and intrinsic value, by the idea of mean-reverting, it is more likely for the stock price to drop.
In other words, this is a way of relative valuation and a smaller IMVF indicates a better performance of the stock.

PLan

We plan to construct IMVF by both linear model and machine learning methods including adaline, random forests and AdaBoost method.
Then by using the IMVF we construct, predicting the firms value and compare the result of above methods.

Data

  • Sample: Full Index of SHSE & SZSE stocks
  • Time period: 2007.01~2016.12, monthly data.
  • Variables: market value, type of industry, net asset, net income, leverage ratio, revenue growth rate and R&D expense.
  • Data process methods: standardized and PCA methods (subject to change).
