Power law for ensembles of stock prices
نویسندگان
چکیده
In this paper we investigate quantitatively statistical properties of ensemble of stock prices, which no other studies have so far done. We select 1200 stocks traded in the Tokyo Stock Exchange and form a statistical ensemble of daily stock prices for each of the trading days. We found that the tail of the cumulative distribution of ensembles of stock prices is accurately described by a power-law distribution.

In this paper, we quantitatively investigate the statistical properties of a statistical ensemble of stock prices. We selected 1200 stocks traded on the Tokyo Stock Exchange, and formed a statistical ensemble of daily stock prices for each trading day in the 3-year period from January 4, 1999 to December 28, 2001, corresponding to the period of the forming of the internet bubble in Japn, and it...

متن کاملA mechanism leading bubbles to crashes: the case of Japan’s land markets
In this paper we investigate quantitatively statistical properties of ensemble of land prices in Japan in the period from 1981 to 2002, corresponding to the period of bubbles and crashes. We find that the tail of the distributions of ensembles of the land prices in the high price range is well described by a power law distribution, P (S > x) ∼ x−α, and furthermore that as the power-law exponent...
متن کاملWinner-Take-All Correlation-Based Complex Networks for Modeling Stock Market and Degree-Based Indexes
Complex networks are constructed to study correlations between the closing prices for all US stocks that were traded from July 1, 2005 to August 30, 2007. The nodes are the stocks, and the connections are determined by cross correlations of the variations of the stock prices and price returns within a chosen period of time. Specifically, a winner-take-all approach is used to determine if two no...
متن کاملInverse statistics in stock markets: Universality and idiosyncracy
Investigations of inverse statistics (a concept borrowed from turbulence) in stock markets, exemplified with filtered Dow Jones Industrial Average, S&P 500, and NASDAQ, have uncovered a novel stylized fact that the distribution of exit time follows a power law p(τρ) ∼ ρ −α with α ≈ 1.5 at large τρ and the optimal investment horizon τ∗ ρ scales as ρ γ [1,2,3]. We have performed an extensive anal...
