Bitmine vs MicroStrategy Correlation

Average Correlation

strongly correlated

0.79

Current (30-day) 0.89

30-day rolling range +0.53 to +0.90

Bitmine and MicroStrategy are strongly correlated over the past year. With a correlation of 0.79, these assets tend to move together, limiting diversification benefits.

For portfolio construction, this strong correlation means holding both BMNR and MSTR provides limited risk reduction — they're likely to decline together in downturns.

Metric	Value
Current (30-day)	0.89
Average (full period)	0.79
Minimum (30-day rolling)	0.53
Maximum (30-day rolling)	0.90

Correlation measures how closely two assets move together. Values near +1 indicate strong co-movement, near 0 indicates independence, and negative values indicate inverse movement. Current, minimum, and maximum figures are 30-day rolling correlations on shared daily returns.

Drawdown

Maximum Drawdown

BMNR

-78.9%

MSTR

-77.1%

Bitmine experienced its maximum drawdown of -78.9% from 2025-10-06 to 2026-06-30. It has not yet recovered to its previous peak.

MicroStrategy experienced its maximum drawdown of -77.1% from 2025-10-06 to 2026-06-26. It has not yet recovered to its previous peak.

Smaller drawdowns and faster recoveries indicate lower downside risk and greater resilience during market stress.

Bitmine vs MicroStrategy Volatility (BMNR vs MSTR)

BMNR Volatility

92.4%

±5.82% 1-day vol

MSTR Volatility

76.3%

±4.8% 1-day vol

1-day volatility (1σ)

BMNR

±5.82%

MSTR

±4.8%

Bitmine's 92.4% annualized volatility translates to about ±5.82% one-standard-deviation daily volatility.

MicroStrategy's 76.3% annualized volatility translates to about ±4.8% one-standard-deviation daily volatility.

BMNR had the wider volatility profile over this window. That means its day-to-day return distribution was broader; MSTR was calmer, but lower volatility does not by itself mean better returns.

Treat the ± daily figure as a one-standard-deviation estimate from historical returns, not a forecast or expected absolute daily move. For context, 15-18% annualized volatility is roughly ±1% one-standard-deviation daily volatility.

Risk-adjusted ratios

Sharpe Ratio of BMNR and MSTR

Sharpe Ratio: BMNR vs. MSTR

Return per total volatility

Sharpe gives us excess return per unit of risk. Upside and downside volatility both count as risk.

Higher is better

excess return / total volatility

Formula

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

Sharpe ratio measures return per unit of risk (volatility). A higher Sharpe indicates better risk-adjusted performance. Both Sharpe ratios were negative (BMNR -0.51 vs MSTR -1.13), meaning both underperformed the risk-free rate; BMNR was less negative.

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).

Sortino Ratio of BMNR and MSTR

Sortino Ratio: BMNR vs. MSTR

Return per downside volatility

Sortino keeps the return-over-risk idea, but only returns below the target rate count as volatility.

Higher is better

excess return / downside volatility

Formula

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

Sortino ratio measures return per unit of downside risk. Unlike Sharpe, it only counts downside deviation (returns below the target return). BMNR had better downside-adjusted returns.

A higher Sortino is better. It's useful when upside volatility is common (crypto is the obvious example). Downside deviation: BMNR 63.9% vs MSTR 53.3%. 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).

Calmar Ratio of BMNR and MSTR

Calmar Ratio: BMNR vs. MSTR

CAGR per worst drawdown

Calmar compares CAGR against the single deepest peak-to-trough loss over the period.

Higher is better

CAGR / max drawdown

Formula

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

Calmar ratio compares CAGR to maximum drawdown. Higher Calmar means more return per unit of worst drawdown. BMNR posted the higher Calmar ratio.

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

Sterling Ratio of BMNR and MSTR

Sterling Ratio: BMNR vs. MSTR

Return per average drawdown

Sterling smooths the drawdown penalty by using average drawdown events instead of only the worst one.

Higher is better

excess annual return / average deep drawdown

Formula

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

Sterling ratio measures excess return per unit of average drawdown (typically drawdowns worse than 10%). MSTR posted the higher Sterling ratio.

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

Treynor Ratio of BMNR and MSTR

Treynor Ratio: BMNR vs. MSTR

Excess return per market beta

Treynor divides excess annualized return by beta — the sensitivity of the asset to broad-market moves. The slope shown is each asset’s beta vs SPY.

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 risk (beta) instead of total volatility. BMNR posted the higher Treynor ratio.

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

Ulcer Index of BMNR and MSTR

Ulcer Index: BMNR vs. MSTR

Drawdown pain

Ulcer Index is a risk index, not a return-over-risk ratio. Lower means smaller and shorter drawdowns.

Lower is better

root-mean-square drawdown

Formula

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

Ulcer Index captures drawdown depth and duration. Lower Ulcer Index means less drawdown pain. MSTR had the lower Ulcer Index (less drawdown pain).

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

Tail Risk & Distribution Shape (1-Year): Bitmine vs. MicroStrategy

This section looks at the shape of daily returns, not just the average. Tail stats are computed per asset on its own daily series (crypto includes weekends). We use daily log returns $\ln\left(\frac{P_t}{P_{t-1}}\right)$ so multi-day moves add cleanly.

Definitions: Value at Risk (VaR), Expected Shortfall, skew, kurtosis, and fat tails.

Tail Risk & Distribution Shape: BMNR vs. MSTR (1-Year)

Actual daily return tails

The bars are real daily log-return observations from the article window. Darker bars are observations at or beyond each asset’s 5% VaR cutoff.

Observed returns

VaR marks the 5th percentile loss cutoff; Expected Shortfall averages the observations beyond that cutoff.

Formula

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

Metric (1-Year)	BMNR	MSTR
5% VaR (daily log return)	-10.18%	-7.26%
5% Expected Shortfall (CVaR)	-11.50% (worst 13 days)	-9.62% (worst 13 days)
Skew	0.19	0.40
Excess kurtosis	0.05	2.28
2σ tail days (down / up)	2 / 6	3 / 5
Worst day	-14.29% (2026-02-05)	-17.12% (2026-02-05)
Best day	+19.62% (2025-11-24)	+26.11% (2026-02-06)

Downside co-moves (2σ) — 1-Year

Computed on shared dates only (n=250). A “2σ downside move” means a shared-close log return more than 2 standard deviations below that asset’s own mean on this shared-date series. Dates below show simple returns (%) for readability.

Downside co-move map: BMNR vs. MSTR (2σ)

Shared-close daily returns

Dots mark actual downside days: asset-colored dots are one-sided downside moves, and red dots are joint downside days. Grey dots add sampled shared-return context when available. The shaded lower-left zone shows where both BMNR and MSTR crossed their own 2σ downside threshold.

Dates below are shared-date observations. The “Date” is the period end (close). Tail thresholds are computed on log returns, but the table shows simple returns (%) for readability. Returns are computed from the previous shared close to this one (for example, Friday → Monday includes weekend moves).

2026-02-05	-14.29%	-17.12%

Read this as “how ugly the ugly days get”, not as a precise forecast. One-year samples are small, so tail estimates are inherently noisy.

MSTR: 3.81% over 2025-08-22 → 2026-08-21.
Volatility drag (rule of thumb): Estimated from annualized volatility (simple returns). For the log-return framing, see Log returns.

BMNR: ≈ -42.7%/yr
