Google vs Microsoft Correlation
Google and Microsoft are weakly correlated over the past year. With a correlation of 0.24, these assets show meaningful independence, offering diversification benefits when held together.
For portfolio construction, this weak correlation suggests that combining GOOG and MSFT could reduce overall portfolio variance. However, correlations can increase during market stress.

| Average (full period) | 0.24 |
| Minimum | -0.17 |
| Maximum | 0.92 |
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.

Google and Microsoft: Risk Analysis
Google experienced its maximum drawdown of -16.5% from 2025-03-07 to 2025-04-08. It took 62 days to recover.
Microsoft experienced its maximum drawdown of -28.9% from 2025-10-28 to 2026-02-23. 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 GOOG and MSFT
Sharpe ratio measures return per unit of risk (volatility). A higher Sharpe indicates better risk-adjusted performance. GOOG had a higher Sharpe (2.04 vs 0.07), 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 GOOG and MSFT
Sortino ratio measures return per unit of downside risk. Unlike Sharpe, it only counts downside deviation (returns below the target return). GOOG 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: GOOG 18.6% vs MSFT 18.6%. 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 GOOG and MSFT
Calmar ratio compares CAGR to maximum drawdown. Higher Calmar means more return per unit of worst drawdown. GOOG 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 GOOG and MSFT
Sterling ratio measures excess return per unit of average drawdown (typically drawdowns worse than 10%). GOOG 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 GOOG and MSFT
Treynor ratio measures excess return per unit of market risk (beta) instead of total volatility. GOOG 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 GOOG and MSFT
Ulcer Index captures drawdown depth and duration. Lower Ulcer Index means less drawdown pain. GOOG 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): Google vs. Microsoft
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 so multi-day moves add cleanly.

| 5% Expected Shortfall (CVaR) | -3.76% (worst 13 days) | -3.78% (worst 13 days) |
| Skew | 0.41 | -0.09 |

Downside co-moves (2σ) — 1-Year
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.
Google vs Microsoft Volatility (GOOG vs MSFT)
Google's annualized volatility of 30.6% means it typically moves ±1.93% on any given day.
Microsoft's annualized volatility of 26.7% means it typically moves ±1.68% on any given day.
GOOG's higher volatility means a wider path to returns — this can be attractive for tactical, shorter-term exposure, while MSFT's smoother profile may better suit long-term allocators seeking steadier growth.
For comparison, the S&P 500 typically has 15-18% annualized volatility, translating to roughly ±1% daily moves. Higher volatility means larger potential gains but also larger potential losses.
