Fidelity Wise Origin Bitcoin Fund (FBTC)

Fidelity Wise Origin Bitcoin Fund Tail Risk

Tail-risk stats use daily return distributions rather than simple end-point returns. They show how ugly the left tail has been, how severe the worst 5% of days were, and whether returns were skewed toward outsized upside or downside shocks.

The histogram shows the shape of Fidelity Wise Origin Bitcoin Fund's daily log returns over the Since inception window. Bars left of the 5% VaR marker are the worst 5% of days; the ES marker is the average loss inside that tail. Skew and excess kurtosis describe whether the distribution is symmetric around zero and whether extreme days are more common than a Normal distribution predicts.

Formula $\displaystyle \mathrm{VaR}_{5\%} = Q_{0.05}(R),\quad \mathrm{ES}_{5\%} = \mathbb{E}[R \mid R \le \mathrm{VaR}_{5\%}]$

Less negative daily VaR and Expected Shortfall values mean the left tail was less violent. Skew and excess kurtosis help distinguish between steady compounding and a path dominated by occasional extreme moves.
