- Risk-adjusted return: Sharpe was 0.95 and Sortino was 1.56 over 5Y. Sharpe counts total volatility; Sortino focuses on downside volatility.
- Volatility & drawdown: Annualized volatility was 90.6% over 1Y and 81.2% over 5Y ; max drawdown was -43.0% over 1Y and -83.0% over 5Y .
- Tail risk (Expected Shortfall): Over 5Y, daily VaR (5%) was -7.8% and Expected Shortfall was -10.3%. VaR is the cutoff; Expected Shortfall is the average move inside the worst 5% of daily returns.
- Skew & kurtosis: Over 5Y, skew was 0.63 and excess kurtosis was 4.07. Skew shows return asymmetry; excess kurtosis shows how fat the tails were versus a Normal distribution.

Risk-adjusted ratios
These ratios compare return against different definitions of risk: total volatility, downside volatility, drawdowns, benchmark beta, and time spent underwater.
Rocket Lab USA Sharpe Ratio
RKLB Sharpe Ratio (5Y)
Return per total volatilityThe dot sits at (Rocket Lab USA'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.
Sharpe ratio Rocket Lab USA'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: 2.29; 5Y: 0.95.
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).
Rocket Lab USA Sortino Ratio
RKLB Sortino Ratio (5Y)
Return per downside volatilityRocket Lab USA'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.
Sortino ratio Rocket Lab USA'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: 3.92; 5Y: 1.56.
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).
Rocket Lab USA Calmar Ratio
RKLB Calmar Ratio (5Y)
CAGR per worst drawdownRocket Lab USA'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.
Calmar ratio Rocket Lab USA'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: 10.55; 5Y: 0.77.
Calmar is computed on each asset's full 365-day lookback and uses the max drawdown over that same window.
Rocket Lab USA Sterling Ratio
RKLB Sterling Ratio (5Y)
Return per average drawdownThe underwater curve shows Rocket Lab USA'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.
Sterling ratio Rocket Lab USA'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: 18.86; 5Y: 2.04.
Sterling uses average drawdown events deeper than 10% and subtracts the risk-free rate to report excess return.
Rocket Lab USA Ulcer Index
RKLB Ulcer Index (5Y)
Drawdown painThe underwater curve shows how deep and how long Rocket Lab USA's drawdowns were. Ulcer is the root-mean-square of that curve — both depth and persistence count, so lower is better.
Ulcer Index Rocket Lab USA's Ulcer Index measures both the depth and persistence of drawdowns. Lower is better because it means fewer and shallower underwater periods. 1Y: 18.18; 5Y: 59.27.
Ulcer Index is computed from each asset's drawdown series over the full lookback window.
Rocket Lab USA Treynor Ratio
RKLB Treynor Ratio (5Y)
Excess return per beta vs SPYThe line's slope is Rocket Lab USA'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.
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.
Rocket Lab USA 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 Rocket Lab USA'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.
RKLB daily return distribution (5Y)
RKLB daily return distribution (5Y)Log-return histogram with Value-at-Risk and Expected Shortfall markers at the 5% left tail.
| Metric | 1Y | 5Y |
|---|---|---|
| VaR (5%) | -8.8% Historical daily threshold | -7.8% Historical daily threshold |
| Expected shortfall (5%) | -10.8% Beyond the VaR threshold | -10.3% Beyond the VaR threshold |
| Skew | 0.41 | 0.63 |
| Excess kurtosis | 2.31 | 4.07 |
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.
