Tesla and Nvidia: Risk Analysis

Tesla experienced its maximum drawdown of -24.3% from 2025-02-28 to 2025-04-08. It took 31 days to recover.

Nvidia experienced its maximum drawdown of -24.5% from 2025-02-28 to 2025-04-04. It took 39 days to recover.

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

Sharpe Ratio of TSLA and NVDA

TSLA Sharpe Ratio

↑ 0.88

NVDA Sharpe Ratio

↑ 1.26

Sharpe ratio measures return per unit of risk (volatility). A higher Sharpe indicates better risk-adjusted performance. NVDA had a higher Sharpe (1.26 vs 0.88), indicating better risk-adjusted performance.

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 TSLA and NVDA

TSLA Sortino Ratio

↑ 1.34

NVDA Sortino Ratio

↑ 1.95

Sortino ratio measures return per unit of downside risk. Unlike Sharpe, it only counts downside deviation (returns below the target return). NVDA 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: TSLA 40.3% vs NVDA 27.8%. 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 TSLA and NVDA

TSLA Calmar Ratio

↑ 1.99

NVDA Calmar Ratio

↑ 2.58

Calmar ratio compares CAGR to maximum drawdown. Higher Calmar means more return per unit of worst drawdown. NVDA 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 TSLA and NVDA

TSLA Sterling Ratio

↑ 2.42

NVDA Sterling Ratio

↑ 2.82

Sterling ratio measures excess return per unit of average drawdown (typically drawdowns worse than 10%). NVDA 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 TSLA and NVDA

TSLA Treynor Ratio

↑ 0.25

NVDA Treynor Ratio

↑ 0.32

Treynor ratio measures excess return per unit of market risk (beta) instead of total volatility. NVDA 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 TSLA and NVDA

TSLA Ulcer Index

10.42%

NVDA Ulcer Index

8.39%

Ulcer Index captures drawdown depth and duration. Lower Ulcer Index means less drawdown pain. NVDA 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): Tesla vs. Nvidia

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.

Metric (1-Year)	TSLA	NVDA
5% VaR (daily log return)	-5.48%	-4.04%
5% Expected Shortfall (CVaR)	-8.24% (worst 13 days)	-5.98% (worst 13 days)

Computed on shared dates only (n=249). 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.

Inputs & conventions

Shared window for pair metrics: 2025-02-27 → 2026-02-25 (last shared close).
Rolling correlation sample (shared closes): 220 rolling 30-day values (from 249 shared daily returns).
Annualization (days/year): TSLA: 252 days/year; NVDA: 252 days/year.
Risk-free rate: Uses the 3-month U.S. Treasury yield (FRED: DGS3MO), averaged over each asset’s window:

TSLA: 4.20% over 2025-02-27 → 2026-02-25.

NVDA: 4.20% over 2025-02-27 → 2026-02-25.
Volatility drag (rule of thumb): Estimated from annualized volatility (simple returns). For the log-return framing, see Log returns.

TSLA: ≈ -18.5%/yr

NVDA: ≈ -9.4%/yr
Data alignment: No forward fill. Correlation and tail co-moves are computed on shared closes only.
For cross-calendar pairs (e.g., crypto vs stocks), weekend/holiday moves roll into the next shared close.
Return conventions: Volatility/Sharpe/Sortino use simple daily returns. Tail-risk uses daily log returns for distribution stats (but tables show simple returns). Log returns.
