Gold vs Nvidia Correlation

-0.09 Average Correlation

Gold and Nvidia were negatively correlated in 2025. With a negative correlation of -0.09, these assets tended to move in opposite directions, potentially offering strong diversification benefits.

For portfolio construction, this negative correlation suggests that combining XAU and NVDA could significantly reduce portfolio variance through offsetting movements.

Metric	Value
Current (30-day)	0.08
Average (full period)	-0.09
Minimum	-0.66
Maximum	0.46

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.

Gold and Nvidia: Risk Analysis

Gold experienced its maximum drawdown of -9.7% from 2025-10-20 to 2025-11-04. It has not yet recovered to its previous peak.

Nvidia experienced its maximum drawdown of -36.9% from 2025-01-06 to 2025-04-04. It has not yet recovered to its previous peak.

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

Sharpe Ratio of XAU and NVDA

XAU Sharpe Ratio

↑ 2.34

NVDA Sharpe Ratio

↑ 0.77

Sharpe ratio measures return per unit of risk (volatility). A higher Sharpe indicates better risk-adjusted performance. XAU had a higher Sharpe (2.34 vs 0.77), 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 XAU and NVDA

XAU Sortino Ratio

↑ 3.58

NVDA Sortino Ratio

↑ 1.10

Sortino ratio measures return per unit of downside risk. Unlike Sharpe, it only counts downside deviation (returns below the target return). XAU 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: XAU 12.7% vs NVDA 34.9%. 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).

Tail Risk & Distribution Shape (2025): Gold 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 (2025)	XAU	NVDA
5% VaR (daily log return)	-1.75%	-4.62%
5% Expected Shortfall (CVaR)	-2.69% (worst 13 days)	-7.58% (worst 13 days)
Skew	-0.45	-0.53
Excess kurtosis	2.31	7.83
2σ tail days (down / up)	8 / 9	7 / 2
Worst day	-5.31% (2025-10-21)	-16.97% (2025-01-27)

Downside co-moves (2σ) — 2025

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.

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).

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.

Inputs & conventions

Shared window for pair metrics: 2025-01-01 → 2025-12-31 (last shared close).
Rolling correlation sample (shared closes): N/A
Annualization (days/year): XAU: 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:

XAU: 4.22%.

NVDA: 4.22%.
Volatility drag (rule of thumb): Estimated from annualized volatility (simple returns). For the log-return framing, see Log returns.

XAU: ≈ -1.9%/yr

NVDA: ≈ -12.3%/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.

Formulas

Daily simple return

r_t = \frac{P_t}{P_{t-1}} - 1

Volatility

\sigma_{ann} = \sigma(r_t)\sqrt{A}

Volatility drag (approx.)

\text{drag} \approx \tfrac{1}{2}\sigma_{ann}^2

Sharpe Ratio

S = \frac{A\,\bar{r} - r_f}{\sigma(r_t)\sqrt{A}}

Sortino Ratio

So = \frac{A\,\bar{r} - r_f}{\sqrt{\mathbb{E}[\min(0,\,r_t - r_f/A)^2]}\,\sqrt{A}}

Maximum Drawdown

MDD = \min_t\left(\frac{P_t}{\max_{s \le t} P_s} - 1\right)

Average Correlation

\rho = \frac{\operatorname{cov}(r^A,\,r^B)}{\sigma_A\,\sigma_B}

Log returns

\ell_t = \ln\left(\frac{P_t}{P_{t-1}}\right)
