Eaton Corporation vs NextEra Energy Correlation

0.10 Average Correlation

Eaton Corporation and NextEra Energy are weakly correlated over the past year. With a correlation of 0.10, these assets show meaningful independence, offering diversification benefits when held together.

For portfolio construction, this weak correlation suggests that combining ETN and NEE could reduce overall portfolio variance. However, correlations can increase during market stress.

Metric	Value
Current (30-day)	0.20
Average (full period)	0.10
Minimum	-0.37
Maximum	0.57

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.

Eaton Corporation and NextEra Energy: Risk Analysis

Eaton Corporation experienced its maximum drawdown of -19.1% from 2025-07-28 to 2025-12-17. It took 56 days to recover.

NextEra Energy experienced its maximum drawdown of -11.1% from 2025-04-03 to 2025-04-08. It took 36 days to recover.

Sharpe Ratio of ETN and NEE

ETN Sharpe Ratio

↑ 1.21

NEE Sharpe Ratio

↑ 1.07

Sharpe ratio measures return per unit of risk (volatility). A higher Sharpe indicates better risk-adjusted performance. ETN had a higher Sharpe (1.21 vs 1.07), 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 ETN and NEE

ETN Sortino Ratio

↑ 1.86

NEE Sortino Ratio

↑ 1.50

Sortino ratio measures return per unit of downside risk. Unlike Sharpe, it only counts downside deviation (returns below the target return). ETN 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: ETN 21.3% vs NEE 18.5%. 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 ETN and NEE

ETN Calmar Ratio

↑ 2.43

NEE Calmar Ratio

↑ 2.94

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

ETN Sterling Ratio

↑ 2.68

NEE Sterling Ratio

↑ 2.61

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

ETN Treynor Ratio

↑ 0.31

NEE Treynor Ratio

↑ 0.58

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

ETN Ulcer Index

8.50%

NEE Ulcer Index

5.05%

Ulcer Index captures drawdown depth and duration. Lower Ulcer Index means less drawdown pain. NEE 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): Eaton Corporation vs. NextEra Energy

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.

Computed on shared dates only (n=244). 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: 2025-04-03 → 2026-03-25 (last shared close).
Rolling correlation sample (shared closes): 215 rolling 30-day values (from 244 shared daily returns).
Annualization (days/year): ETN: 252 days/year; NEE: 252 days/year.
Risk-free rate: Uses the 3-month U.S. Treasury yield (FRED: DGS3MO), averaged over each asset’s window:

ETN: 4.18% over 2025-04-03 → 2026-03-25.

NEE: 4.18% over 2025-04-03 → 2026-04-01.
Volatility drag (rule of thumb): Estimated from annualized volatility (simple returns). For the log-return framing, see Log returns.

ETN: ≈ -5.4%/yr

NEE: ≈ -3.3%/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.

Volatility

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

Volatility drag (approx.)
