It is well-known that the distributions of daily and monthly equity returns are leptokurtic (fat-tailed) relative to the normal distribution. In other words, the shape of their return distribution is more peaked than you’d find in a normal, or bell curve, distribution. This distribution is always positive even if some of the rates of return are negative, which will happen 50% of the time in a normal distribution. The future stock price will always be positive Even though there is a remarkable discrepancy between the concepts of behavior of stock prices held by professional stock market analysts, on the one hand, and by academics on the other, the form of the distribution of stock returns is important to both groups because it is a crucial assumption for mean-variance portfolio theory, theoretical more normal in their distribution, as would be expected based on the central limit theorem. The t-distribution with location/scale parameters is shown to be an excellent fit to the daily percentage returns of the S&P 500 Index. Introduction The distribution of stock returns is important for a variety of trading problems. 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.
11 Dec 2008 Here is a chart that plots out the distribution of annual returns of the US stock market as measured by the S&P Market Index*.

Investing some of
Distributions of stock market returns are often presented as bell shaped curves. This representation implies that stock returns are normally distributed, which can depend on the period analyzed The basic assumption that stock price returns follow normal distribution itself is questioned time and again. There is sufficient empirical proof of instances where values fail to adhere to the In this section, we empirically analyse potential reasons for quantile 0.75 returns to have superior forecasting performance for the next year's stock return distribution, as compared to other quantile returns. Specifically, we investigate if quantile 0.75 returns possess superior predictive power for future consumption and investment: if they do, and given that one would expect the stock market to be affected by (expected) changes in future realisations of those two variables, the rationale First, why not just do a histogram of the first differences of daily returns to identify the underlying distribution? After all, people say movement of stock market indexes are a random walk. OK, well you could do that, and the resulting distribution would also look “Laplacian” with a pointy peak and relative symmetry. However, I am The stable distribution has been appreciated as a distribution to model stock returns for both statistical and economic reasons. Statistically speaking, the stable distribution has domains of attraction and belongs to its own domain of attraction. It seems natural to use sample variance or sample standard deviation to discriminate between finite variance and infinite variance distributions. Unfortunately, the power based on the sample variance or sample standard deviation may not be good Okay, so I do this (to see what the distribution of Total n-day Gains might look like): I look at the daily returns for GE stock over the past 10 years. That's (about) 2500 daily returns. I pick 25 successive returns at random and calculate the 25-day gain. I repeat this ritual a jillion times and plot the distribution of these monthly gains.
In this paper, we investigate the normality of the distribution of daily returns of major stock market indices. We find that the normal distribution is not a good model Our concern is to provide a simple and economically justified model of stock market returns. The basic empirical fact that the return distributions have bigger tails 6 Jan 2007 This paper examines the fit of three different statistical distributions to the returns of the S&P 500 Index from. 1950-2005.
