Statistical analysis of stock returns

These conclusions are based on a variety of alternative statistical The analysis of the relationship between stock returns and fundamental variables is  of variance, correlation, and beta, to study the statistical properties of asset returns at multiple time horizons. This framework connects spectral analysis to the  4 Sep 2019 We apply the methodology to the stock markets as an example of its application, In this regard, Approximate Entropy (ApEn) is a statistical measure of the level of we validate our results with a similar analysis using Sample Entropy and ( a) IBEX 35 for 2005 open daily data transformed as log return.

This article surveys the evolution of stock market trading over a 60-year period. 1960, when there was no database widely available to conduct a statistical analysis of stock price. A major finding was the heavy-tailed nature of stock returns. STATISTICAL PROPERTIES OF STATISTICAL ENSEMBLES OF STOCK We analyze each ensemble of stock returns by extracting its first four central  stock market follows an exponential distribution with an exponent of β ≈ 0.7. The Hurst exponent analysis of the original return, and its magnitude and sign  Analysis of the unconditional distribution of stock returns has a long tradition in topic is not restricted to the pure determination of statistical distribution or to its  stocks rates of return, we adopted the statistical methodology of analysis of variance (ANOVA). According to Neter, Kutner, Nachtsheim and Wasserman ( 1996),  We propose a model-free omnibus statistical procedure to check whether the direction ity, skewness and kurtosis of past excess stock returns can be used to predict the the synthesis of the characteristic function and spectral analysis. 1 Sep 2015 We perform a statistical analysis to check the consistency of the tails of the empirical distributions with power law behavior across different time

By using one of the common stock probability distribution methods of statistical calculations, an investor and analyst may determine the likelihood of profits from a holding.

Abstract—The statistical analysis of Chinese stock market fluctuations modeled by the interacting particle systems has been done in this paper. The contact model and voter model of the interacting particle systems are presented in this paper, where they are the continuous time Markov processes. Stock Market Yearly Returns -- The Best and the Worst It was the best of times, it was the worst of times. Investing in a low-cost stock market index tracking fund is simply one of the simplest and lowest risk ways to expose yourself to the dynamic wealth creation of the U.S.A. or any other major developed world economy. Returns-based style analysis is a statistical technique used in finance to deconstruct the returns of investment strategies using a variety of explanatory variables. The model results in a strategy's exposures to asset classes or other factors, interpreted as a measure of a fund or portfolio manager's style.

Whenever there is significant "skewness" or kurtosis, the return distribution departs from the normal distribution, complicating statistical inferences on the analysis of expected return and Thank you, this is a great article. I noticed a similar distribution for stock returns and similar results when fitting a gaussian distribution. Larger returns (say, 3+ standard deviations away from the mean of approximately 0) were predicted with very low frequencies, while the returns closer to 0 were a good fit to the model. By using one of the common stock probability distribution methods of statistical calculations, an investor and analyst may determine the likelihood of profits from a holding.

6 Nov 2018 PDF | We study statistical properties of the daily log returns of the historical stock price indices of the Colombo Stock Exchange in Sri Lanka. Black & Scholes assumed in their seminal work  that the returns from the underlying stock are normally distributed.
