Please advise whether the following is a normal occurrence:

enter image description here

In the above table I have Autocorrelation at lag1, LB, Skew, Kurt and JB test.

I have noticed that whenever the value of Kurt increases, the JB increases exponentially. In some cases I even have JB=106000.35

Am using Eviews 9.5 to calculate it.

Please advise on the results of the above (as I have to report these values in the table).

Much obliged West

    $\begingroup$ You can verify it yourself using the formula but this doesn’t seem unreasonable. This is more of a statistic question than Quantitative Finance question si I will close. $\endgroup$ – Bob Jansen Apr 9 '19 at 20:28
  • $\begingroup$ I have verified it with the formula, thanks. To me it is quant finance as am using it to analyse hedge fund investments. PS. Should I simply ignore extremely high JB values in my description of the results? $\endgroup$ – West Ray Apr 9 '19 at 21:56

    $\begingroup$ It is evidence that the distribution is not Normal, the skewness and kurtosis are excessive compared to those of a Normal Distribution. Which is not too surprising for daily returns. $\endgroup$ – Alex C Apr 10 '19 at 1:11
