Bitcoin experienced its maximum drawdown of -48.9% from 2025-10-06 to 2026-02-04. 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 IGV and BTC

IGV Sharpe Ratio

↓ -0.71

BTC Sharpe Ratio

↓ -0.30

Sharpe ratio measures return per unit of risk (volatility). A higher Sharpe indicates better risk-adjusted performance. Both Sharpe ratios were negative (BTC -0.30 vs IGV -0.71), meaning both underperformed the risk-free rate; BTC was less negative.

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 IGV and BTC

IGV Sortino Ratio

↓ -0.93

BTC Sortino Ratio

↓ -0.42

Sortino ratio measures return per unit of downside risk. Unlike Sharpe, it only counts downside deviation (returns below the target return). BTC 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: IGV 19.2% vs BTC 30.2%. 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 IGV and BTC

IGV Calmar Ratio

↓ -0.42

BTC Calmar Ratio

↓ -0.33

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

IGV Sterling Ratio

↓ -0.53

BTC Sterling Ratio

↓ -0.66

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

IGV Treynor Ratio

↓ -0.14

BTC Treynor Ratio

↓ -0.55

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

IGV Ulcer Index

14.59%

BTC Ulcer Index

24.20%

Ulcer Index captures drawdown depth and duration. Lower Ulcer Index means less drawdown pain. IGV 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): iShares Tech Software Sector vs. Bitcoin

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.
