platykurtic: School of Stocks Returns Distribution, Skewness, and Kurtosis

negative excess kurtosis

For a sample size of 100 or larger, a skewness coefficient of ±0.5 is considered unusually large. Distributions are technically defined as having a kurtosis of zero, although the distribution doesn’t have to be exactly zero in order for it to be classified as mesokurtic. In terms of shape, a platykurtic distribution has thinner tails. Save taxes with ClearTax by investing in tax saving mutual funds online.

Information about What curve representaion of sample Mean or – 3 standard deviation a) leptokurtic b) platykurtic C) mesokurtic? Find important definitions, questions, meanings, examples, exercises and tests below for What curve representaion of sample Mean or – 3 standard deviation a) leptokurtic b) platykurtic C) mesokurtic?. Most investors believe that a leptokurtic distribution resembles stock market returns better than a platykurtic distribution. That is, while most returns will be near to the market’s average return, yields will frequently diverge significantly from the mean. In platykurtic markets, such dramatic and surprising events, commonly known as “black swans,” are less likely to occur. When determining where to invest, investors will analyze which statistical distributions are connected with certain sorts of investments.

Most of the https://1investing.in/ from equity investments and hedge funds are leptokurtic in distribution. Kurtosis is a statistical measure that measures the peakedness of distribution. A distribution that is more peaked than a normal distribution is called leptokurtic. A distribution that is less peaked than a normal distribution is called platykurtic. As a result, most conservative investors may avoid investing in leptokurtic markets and instead focus on investments that produce platykurtic returns.

Such distributions differ based on how much excess kurtosis they have, which is related to the likelihood of extreme positive or negative events. A leptokurtic distribution has a higher kurtosis than a mesokurtic distribution. This distribution has lengthy tails as one of its characteristics. The word “lepto-” signifies “thin,” which helps people recall the form of a leptokurtic distribution. T-distributions with tiny degrees of freedom are examples of leptokurtic distributions. Kurtosis is a statistical measure of distribution that is used to characterize it.

Skewness is computed as the average cubed deviation from the mean standardized by dividing the standard deviation cubed to make the measure free of scale. The skewness is positive for positively skewed distribution, negative for negatively skewed distribution, and zero for symmetrical distribution. International real estate, equities from international emerging nations, and commodities were among the asset classes with intermediate degrees of excess kurtosis. Given their tolerance for potential black swan events, an investor looking at this data could rapidly determine what types of assets they want to invest in. Most investors assume that a leptokurtic distribution more closely approaches stock market returns than a platykurtic one.

Kurtosis is the property of a frequency distribution which expresses its relative peakedness. Kurtosis refers to the extent to which unimodal frequency curve is peaked. In the next chapter, we will continue our discussion of statistical measures of risk by talking about covariance and correlation. For a sample size of 100 or larger, an excess kurtosis of greater than one is considered unusually high. Fewer values in the tails and fewer values close to the mean (i.e. the curve has a flat peak and has more dispersed scores with lighter tails).

Hence, leptokurtic distributions have a fairly high likelihood of extreme events, while the reverse is true for platykurtic distributions. The excess kurtosis is the kurtosis of a sample minus the kurtosis of a normal distribution or the kurtosis of a sample minus three. A leptokurtic distribution has a kurtosis greater than three and thus has a positive excess kurtosis.

A platykurtic distribution would, therefore, have thinner tails than a normal distribution, leading to less extreme positive or negative events. In general, leptokurtic distributions have heavier tails or a higher probability of extreme outlier values when compared to mesokurtic or platykurtic distributions. A platykurtic distribution is the last form of distribution.

Therefore, a distribution with kurtosis greater than three would be labeled a leptokurtic distribution. A distribution with positive excess kurtosis is called leptokurtic. The kurtosis statistic of this distribution is comparable to that of a normal distribution, implying that the distribution’s extreme value characteristic is close to that of a normal distribution. While choosing where to invest, investors will consider which statistical distributions are correlated with the various types of investments.

A collection of data may be shown in one of three kurtosis categories. All kurtosis metrics are compared to a conventional normal distribution, often known as a bell curve. One of the most well known leptokurtic distributions is Student’s t distribution. Besides normal distributions, binomial distributions for whichp is close to 1/2 are considered to be mesokurtic. Leptokurtic distributions are distributions with kurtosis larger than that of a normal distribution.

Platykurtic Distribution in the Real World

A platykurtic distribution has a kurtosis lesser than three and thus has a negative excess kurtosis. A mesokurtic distribution is identical to the normal distribution in peak and has a kurtosis of three and an excess kurtosis of zero. The term “platykurtic” describes a statistical distribution with a negative excess kurtosis value. The opposite of a platykurtic distribution is a leptokurtic distribution.

Assets and markets with platykurtic distributions may appeal to risk-averse investors since they are less likely to deliver severe results. The standard distribution, which is a type of mesokurtic distribution, has three kurtoses. Therefore, kurtosis distributions greater than three are said to have „positive excess kurtosis,“ while those with less than three kurtoses are said to have „negative excess kurtosis.“ A leptokurtic distribution is the opposite of a platykurtic distribution.

Earlier in this chapter, we spoke about skewness and kurtosis, which are the third and the fourth central moment, respectively, in statistics . When observations in the data set are normally distributed about the mean, one can use standard deviation as an effective measure of risk. That said, keep in mind that standard deviation assumes a distribution that is normal. In the real word however, the distribution of security returns is not always normal. In fact, there is a tendency for security returns to get asymmetric and exhibit skewness and kurtosis.

The word “platy-” means “wide,” and it refers to a short, broad-looking peak, however this is a historical misconception. Uniform distributions have wide peaks and are platykurtic, while the beta distribution is platykurtic and has an indefinitely pointed peak. Because their extreme values are fewer than those of the normal distribution, both of these distributions are platykurtic. Platykurtic return distributions are steady and predictable for investors in the sense that extreme returns are infrequent. Three specific forms of statistical distribution exist—leptokurtic, mesokurtic, and platykurtic.

Investors will analyze which statistical distributions are connected with various sorts of assets when deciding where to invest. Platykurtic-distributed assets and markets may appeal to risk-averse investors since they are less likely to produce extreme outcomes. The word „platykurtic“ refers to a statistical distribution where the value of excess kurtosis is negative.

Hence, from the above points, one can conclude that a distribution that is abnormally tall and peaked is said to be Leptokurtic. Check your Securities /MF/ Bonds in the consolidated account statement issued by NSDL/CDSL every month.
