Sharpe Ratio of FCX and SCCO

FCX Sharpe Ratio

↑ 1.14

SCCO Sharpe Ratio

↑ 1.84

Sharpe ratio measures return per unit of risk (volatility). A higher Sharpe indicates better risk-adjusted performance. SCCO had a higher Sharpe (1.84 vs 1.14), 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 FCX and SCCO

FCX Sortino Ratio

↑ 1.57

SCCO Sortino Ratio

↑ 2.85

Sortino ratio measures return per unit of downside risk. Unlike Sharpe, it only counts downside deviation (returns below the target return). SCCO 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: FCX 37.0% vs SCCO 29.0%. 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 FCX and SCCO

FCX Calmar Ratio

↑ 1.96

SCCO Calmar Ratio

↑ 4.55

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

FCX Sterling Ratio

↑ 2.56

SCCO Sterling Ratio

↑ 7.12

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

FCX Treynor Ratio

↑ 0.36

SCCO Treynor Ratio

↑ 0.65

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

FCX Ulcer Index

10.37%

SCCO Ulcer Index

7.09%

Ulcer Index captures drawdown depth and duration. Lower Ulcer Index means less drawdown pain. SCCO 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): Freeport-McMoRan vs. Southern Copper

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.

Inputs & conventions

Shared window for pair metrics: 2025-02-18 → 2026-02-13 (last shared close).
Rolling correlation sample (shared closes): 220 rolling 30-day values (from 249 shared daily returns).
Annualization (days/year): FCX: 252 days/year; SCCO: 252 days/year.
Risk-free rate: Uses the 3-month U.S. Treasury yield (FRED: DGS3MO), averaged over each asset’s window:

FCX: 4.20% over 2025-02-18 → 2026-02-13.

SCCO: 4.20% over 2025-02-18 → 2026-02-13.
Volatility drag (rule of thumb): Estimated from annualized volatility (simple returns). For the log-return framing, see Log returns.

FCX: ≈ -13.0%/yr

SCCO: ≈ -10.0%/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.
