BOME: Return Excess Kurtosis (365D)
Book of Meme Return Excess Kurtosis (365D) was 8.33 on 10 Nov 2026 (latest daily value).
The excess kurtosis of BOME's daily returns over the last 365 days: how heavy the tails are.
Why use it. High values mean extreme days are far more common than a normal distribution would suggest. How to read it. 0 is a normal distribution's tails; above 3 is very fat-tailed.
Calculation. m4 / m2^2 - 3 of the last 365 daily returns (population central moments). From CryptoKeyhole's own US dollar price chart of BOME, closed periods only. Returns are 24-hour returns r = close / close 24 hours earlier - 1; daily values use the closes of UTC days, hourly values recompute the same statistic at every hour from the closes 24, 48 ... hours before it, so a day's last hour gives its daily value wherever the hourly closes are complete. A window of N days needs N + 1 closes exactly a day apart: a missing close leaves every window that needs it empty, nothing is filled in. The open UTC day shows a labelled partial at the latest completed hour. History starts once the price chart has the window's closes; it is a description of the past, not a forecast.
