MU Sharpe Ratio (Since inception)

Return per total volatility

The dot sits at (Micron Technology'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 return Annualized volatility 0 75% vol 67.3% · excess +162.2%
excess annualized return / total volatility
Formula Sharpe=E[R]−RfσR\displaystyle \mathrm{Sharpe} = \frac{\mathbb{E}[R] - R_f}{\sigma_R}

Sharpe ratio Micron Technology'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: 3.67; Since inception: 2.41.

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).

MU Sortino Ratio (Since inception)

Return per downside volatility

Micron Technology'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
Frequency (days) Daily return (%) target -17.6% +20.2% 46 0
excess annualized return / downside volatility
Formula Sortino=E[R]−Rfσdown\displaystyle \mathrm{Sortino} = \frac{\mathbb{E}[R] - R_f}{\sigma_{\mathrm{down}}}

Sortino ratio Micron Technology'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: 6.63; Since inception: 3.83.

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).

MU Calmar Ratio (Since inception)

CAGR per worst drawdown

Micron Technology'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
0% MU Since inception +314.3% -40.8%
CAGR / max drawdown
Formula Calmar=CAGR∣MaxDD∣\displaystyle \mathrm{Calmar} = \frac{\mathrm{CAGR}}{|\mathrm{MaxDD}|}

Calmar ratio Micron Technology'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: 24.20; Since inception: 7.71.

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

Micron Technology Sterling Ratio

MU Since inception Sterling ratio

Deeper research window

MU Sterling Ratio (Since inception)

Return per average drawdown

The underwater curve shows Micron Technology'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
0% -11% -21% -32% -43% 10% drawdown threshold
excess CAGR / average deep drawdown
Formula Sterling=CAGR−RfD‾>10%\displaystyle \mathrm{Sterling} = \frac{\mathrm{CAGR} - R_f}{\overline{D}_{>10\%}}

Sterling ratio Micron Technology'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: 36.97; Since inception: 13.41.

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

MU Ulcer Index (Since inception)

Drawdown pain

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

Lower is better
0% -11% -21% -32% -43%
root-mean-square drawdown
Formula UI=E[Dt2]\displaystyle \mathrm{UI} = \sqrt{\mathbb{E}[D_t^2]}

Ulcer Index Micron Technology's Ulcer Index measures both the depth and persistence of drawdowns. Lower is better because it means fewer and shallower underwater periods. 1Y: 7.50; Since inception: 12.61.

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

Micron Technology Treynor Ratio

↑ 0.87
Beta 2.62 vs SPY
MU Since inception Treynor
↑ 0.72
Beta 2.27 vs SPY

MU Treynor Ratio (Since inception)

Excess return per beta vs SPY

The line's slope is Micron Technology'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
Asset return Market return 0 0 β 2.27
excess return / market beta
Formula Treynor=E[R]−Rfβ\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.

Micron Technology 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 Micron Technology'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.

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.
