Sharpe Ratio of IGV and QQQ

IGV Sharpe Ratio

↓ -0.71

QQQ Sharpe Ratio

↑ 1.59

Sharpe ratio measures return per unit of risk (volatility). A higher Sharpe indicates better risk-adjusted performance. IGV had a negative Sharpe (-0.71) while QQQ was positive (1.59), indicating QQQ had meaningfully better risk-adjusted performance in this period.

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 QQQ

IGV Sortino Ratio

↓ -0.93

QQQ Sortino Ratio

↑ 2.37

Sortino ratio measures return per unit of downside risk. Unlike Sharpe, it only counts downside deviation (returns below the target return). QQQ 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 QQQ 11.4%. 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 QQQ

IGV Calmar Ratio

↓ -0.42

QQQ Calmar Ratio

↑ 2.86

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

IGV Sterling Ratio

↓ -0.53

QQQ Sterling Ratio

↑ 2.51

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

IGV Treynor Ratio

↓ -0.14

QQQ Treynor Ratio

↑ 0.22

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

IGV Ulcer Index

14.59%

QQQ Ulcer Index

3.18%

Ulcer Index captures drawdown depth and duration. Lower Ulcer Index means less drawdown pain. QQQ 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. Nasdaq 100

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.

Shared window for pair metrics: 2025-04-14 → 2026-04-10 (last shared close).
Rolling correlation sample (shared closes): 219 rolling 30-day values (from 248 shared daily returns).
Annualization (days/year): IGV: 252 days/year; QQQ: 252 days/year.
Risk-free rate: Uses the 3-month U.S. Treasury yield (FRED: DGS3MO), averaged over each asset’s window:

IGV: 4.17% over 2025-04-14 → 2026-04-10.

QQQ: 4.17% over 2025-04-14 → 2026-04-10.
Volatility drag (rule of thumb): Estimated from annualized volatility (simple returns). For the log-return framing, see Log returns.

IGV: ≈ -3.1%/yr

QQQ: ≈ -1.4%/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.
