I found it interesting. I found the 5 days downside amazing. Downside moves are much quicker than upside ones. It takes 5 days to reach -11% vs 20 days to achieve 11%. After the 20 days histogram ... It doesn't move that much ... That's why it's rewarding to be able to time the market. Short term speculators can achieve in a week or a month, What investors achieve in 250 days and more ... I also notice a kind of mean reversion between 50 and 100 days. Of course. We're talking about extreme values. Low Porbability events. Questions. How to interpret the "Normal q-q plot" ? Comments are welcome.
