GOOG experienced its maximum drawdown of -29.3% from 2025-02-04 to 2025-04-08. It took 139 days to recover.

Sharpe Ratio
The Sharpe ratio measures return per unit of risk (volatility). A higher Sharpe indicates better risk-adjusted performance. GOOG delivered 5.3x more return per unit of risk than AAPL.
A Sharpe above 1.0 is generally considered good, above 2.0 is excellent. Negative Sharpe means the asset underperformed the risk-free rate.
Sortino Ratio
The Sortino ratio measures return per unit of downside risk. Unlike Sharpe, it only penalizes negative volatility. GOOG had better downside-adjusted returns.
A higher Sortino is better. It's particularly useful for assets with asymmetric volatility (big gains, smaller losses). Downside volatility: AAPL 23.8% vs GOOG 20.8%.
Understanding Volatility
AAPL's annualized volatility of 32.6% means it typically moves ±2.06% on any given day.
GOOG's annualized volatility of 32.1% means it typically moves ±2.02% on any given day.
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.
