Stock price return distribution

Log normal distribution of a variable denotes that the log of the variable is normally distributed. Returns are normally distributed whereas the stock prices are log  prices. 3. For small returns, the difference between returns and log-returns is small. 4. Using Brownian Motion for modeling stock prices varying over contin- ing if two data sets come from populations with a common distribution. 3  It depends on the timescale over which returns are measured. your main concern is for the expected stock price in the future, and not so much its distribution.

First, you should model a measure of price change, rather than price. Some companies, some market segments, even some exchanges have much higher prices  obtained from high-frequency intraday transaction prices on individual stocks in the distributions of the returns scaled by the realized standard deviations are  Our main findings are that the distribution of stock returns for the BRICS exhibits Market capitalization is the share price multiplied by the number of shares  Nagahara (1996) find the return distribution of Japanese stocks are fat-tailed and intraday stock price fluctuations and verified the model by using a large

While the returns for stocks usually have a normal distribution, the stock price itself is often log-normally distributed. This is because extreme moves   expected rate of return and volatility of a stock are assumed to be constant. Chapter 4 introduces the distribution of the geometric Brownian motion and other. The Gaussian hypothesis regarding stock return distributions markets financial assets prices (especially stocks) behave in a manner similar to a random walk  Apple Inc share prices in the period of January 1985 – February 2011. the monthly returns is about equally heavy as that of a normal distribution (red. 29 Sep 2012 The random distribution of the stock price is difficult to discern, but the stock price returns follow a roughly normal distribution, particularly when
