This result corresponds to most research that copula function can capture the fat-tail phenomenon which prevails over practical market more adequately. Second, the distribution of future portfolio value by proposed method is more diversified than multi-normal method which concentrated on nearly 400,000 with 50,000 times while proposed method ...

For long positions, the risk comes from a decline in the price of the commodity, meaning that traders are merely concerned with the downside of the returns distribution, especially the tailed distribution. However, the extent of fat-tail and skewness influence the tail of the returns distribution.

First, global risks may have a fat tail—that is a low probability of high consequences—and the existence of such fat tails strongly depend on the intrinsic uncertainty of global systems (Ćirković, 2012) (Baum, 2015), (Wiener, 2016) (Sandberg & Landry, 2015).

Step 1: this is a left tail test with the cv =-1.645. Step 2: Calculate the Test Stat, TS from the following Step 3: Decision: Reject H0. Conclusion: Data would support the claim that the proportion of the female who consume too much saturated fat is lower than the proportion of males who consume too much saturated fat significantly

The solutions to the fat tail problem varied; some researchers ignore the fact, some threw out the offensive outliers, some adjusted the numbers, some rejected the random walk model, and some tried to salvage the random walk model by replacing the normal distribution assumption with another stable distribution that better fit the data.
