Kurtosis. So once again, if I were to draw a perfect normal distribution, remember, there's no one normal distribution. You can have different means and different standard deviations. Let's say that's a perfect normal distribution. If I have positive kurtosis, what's going to happen is I'm going to have fatter tails. Let me draw it a little nicer than that. I'm going to have fatter tails, but I'm going to have a more pointy peak.
