CLSK Sharpe Ratio (5Y)

Return per total volatility

The dot sits at (CleanSpark's annualized volatility, its excess annualized return). The slope from the origin to the dot is the Sharpe ratio — steeper means the asset converted risk into return more efficiently.

Higher is better

excess annualized return / total volatility

Formula

\displaystyle \mathrm{Sharpe} = \frac{\mathbb{E}[R] - R_f}{\sigma_R}

Sharpe ratio CleanSpark's Sharpe ratio measures excess return per unit of total volatility. Higher readings mean the asset converted risk into return more efficiently over the same window. 1Y: 0.75; 5Y: 0.34.

A Sharpe above 1.0 is generally considered good, above 2.0 is excellent. Negative Sharpe means the asset underperformed the risk-free rate. Calculated on each asset's full 365-day lookback of available prices and annualized using the asset calendar (365 for crypto, 252 trading days for equities/ETFs/metals).

CLSK Sortino Ratio (5Y)

Return per downside volatility

CleanSpark's daily-return distribution over the long window. Days left of the target line are the only ones Sortino penalizes in the denominator — so a distribution with a fat left tail produces a smaller Sortino even at the same mean return.

Higher is better

excess annualized return / downside volatility

Formula

\displaystyle \mathrm{Sortino} = \frac{\mathbb{E}[R] - R_f}{\sigma_{\mathrm{down}}}

Sortino ratio CleanSpark's Sortino ratio isolates downside volatility instead of all volatility. It is the cleaner lens when you care more about bad downside moves than upside noise. 1Y: 1.16; 5Y: 0.53.

A higher Sortino is better. It's useful when upside volatility is common (crypto is the obvious example). Calculated on each asset's full 365-day lookback of available prices, using the daily risk-free rate as the target return, and annualized using the asset calendar (365 for crypto, 252 trading days for equities/ETFs/metals).

CLSK Calmar Ratio (5Y)

CAGR per worst drawdown

CleanSpark's CAGR bar sits above zero, the max drawdown bar sits below. Calmar is the ratio of those two magnitudes — a shallow drawdown bar with a tall CAGR bar produces a strong Calmar.

Higher is better

CAGR / max drawdown

Formula

\displaystyle \mathrm{Calmar} = \frac{\mathrm{CAGR}}{|\mathrm{MaxDD}|}

Calmar ratio CleanSpark's Calmar ratio measures return per unit of max drawdown. It is useful when the path of losses matters as much as the final return. 1Y: 0.59; 5Y: -0.12.

Calmar is computed on each asset's full 365-day lookback and uses the max drawdown over that same window.

Deeper research window

CLSK Sterling Ratio (5Y)

Return per average drawdown

The underwater curve shows CleanSpark's drawdowns over the long window. Sterling averages every event deeper than the 10% threshold instead of taking only the worst one — so an asset with many mid-size drawdowns scores worse here than on Calmar.

Higher is better

excess CAGR / average deep drawdown

Formula

\displaystyle \mathrm{Sterling} = \frac{\mathrm{CAGR} - R_f}{\overline{D}_{>10\%}}

Sterling ratio CleanSpark's Sterling ratio compares return against deep drawdown pressure. It gives a harsher read on assets that compound well but suffer ugly declines along the way. 1Y: 1.41; 5Y: -0.19.

Sterling uses average drawdown events deeper than 10% and subtracts the risk-free rate to report excess return.

CLSK Ulcer Index (5Y)

Drawdown pain

The underwater curve shows how deep and how long CleanSpark's drawdowns were. Ulcer is the root-mean-square of that curve — both depth and persistence count, so lower is better.

Lower is better

root-mean-square drawdown

Formula

\displaystyle \mathrm{UI} = \sqrt{\mathbb{E}[D_t^2]}

Ulcer Index CleanSpark's Ulcer Index measures both the depth and persistence of drawdowns. Lower is better because it means fewer and shallower underwater periods. 1Y: 36.59; 5Y: 61.36.

Ulcer Index is computed from each asset's drawdown series over the full lookback window.

CleanSpark Treynor Ratio

Beta 3.30 vs SPY

CLSK 5Y Treynor

↑ 0.12

Beta 2.80 vs SPY

CLSK Treynor Ratio (5Y)

Excess return per beta vs SPY

The line's slope is CleanSpark's beta to SPY — steeper means more market-sensitive. Treynor divides excess return by that slope, so an asset can look efficient with a shallow beta and a small return, or inefficient with a steep beta and a big return.

Higher is better

excess return / market beta

Formula

\displaystyle \mathrm{Treynor} = \frac{\mathbb{E}[R] - R_f}{\beta}

Treynor ratio measures excess return per unit of market beta versus SPY. A high Treynor means the asset compensated its market exposure well over this window. A low or negative Treynor means the asset's market risk wasn't rewarded.

Treynor uses beta vs the S&P 500 (SPY) on shared dates and the average 3-month Treasury rate as the risk-free rate.

CleanSpark 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 CleanSpark's daily log returns over the 5Y 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.

Days

worst-5% daily return and the average loss inside it

Formula

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

Metric	1Y	5Y
VaR (5%)	-7.9% Historical daily threshold	-9.2% Historical daily threshold
Expected shortfall (5%)	-11.2% Beyond the VaR threshold	-12.5% Beyond the VaR threshold
Skew	0.09	0.43
Excess kurtosis	1.44	1.11

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.
