Apple vs Google Correlation

Average Correlation

weakly correlated

0.20

Current (30-day) 0.35

30-day rolling range -0.45 to +0.59

Apple and Google were weakly correlated from October 14, 2025 to October 13, 2026. The reported average correlation of 0.20 showed weak linear co-movement in the observed sample; this does not establish independence.

Correlation alone does not establish portfolio risk reduction or predict selloff behavior. This comparison does not model a combined portfolio.

Metric	Value
Current (30-day)	0.35
Average (full period)	0.20
Minimum (30-day rolling)	-0.45
Maximum (30-day rolling)	0.59

Correlation measures linear co-movement of returns: near +1 indicates strong positive co-movement, near 0 indicates weak linear co-movement, and negative values indicate inverse co-movement. Near-zero correlation does not establish independence. Current, minimum, and maximum figures are 30-day rolling correlations on shared daily returns.

Drawdown

Maximum Drawdown

AAPL

-13.8%

GOOG

-20.8%

Apple experienced its maximum drawdown of -13.8% from 2025-12-02 to 2026-03-30. It took 37 days to recover.

Google experienced its maximum drawdown of -20.8% from 2026-02-02 to 2026-03-30. It took 28 days to recover.

Smaller drawdowns and faster recoveries indicate lower downside risk and greater resilience during market stress.

Apple vs Google Volatility (AAPL vs GOOG)

AAPL Volatility

24.5%

±1.54% 1-day vol

GOOG Volatility

31.0%

±1.95% 1-day vol

1-day volatility (1σ)

AAPL

±1.54%

GOOG

±1.95%

Apple's 24.5% annualized volatility translates to about ±1.54% one-standard-deviation daily volatility.

Google's 31.0% annualized volatility translates to about ±1.95% one-standard-deviation daily volatility.

GOOG had the wider volatility profile over this window. That means its day-to-day return distribution was broader; AAPL was calmer, but lower volatility does not by itself mean better returns.

Treat the ± daily figure as a one-standard-deviation estimate from historical returns, not a forecast or expected absolute daily move. For context, 15-18% annualized volatility is roughly ±1% one-standard-deviation daily volatility.

Risk-adjusted ratios

Sharpe Ratio of AAPL and GOOG

Sharpe Ratio: AAPL vs. GOOG

Return per total volatility

Sharpe gives us excess return per unit of risk. Upside and downside volatility both count as risk.

Higher is better

excess return / total volatility

Formula

\displaystyle \mathrm{Sharpe} = \frac{\mathbb{E}[R] - R_f}{\sigma_R}

Sharpe ratio measures return per unit of risk (volatility). A higher Sharpe indicates better risk-adjusted performance. AAPL had a higher Sharpe (1.29 vs 1.18), 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 AAPL and GOOG

Sortino Ratio: AAPL vs. GOOG

Return per downside volatility

Sortino keeps the return-over-risk idea, but only returns below the target rate count as volatility.

Higher is better

excess return / downside volatility

Formula

\displaystyle \mathrm{Sortino} = \frac{\mathbb{E}[R] - R_f}{\sigma_{\mathrm{down}}}

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: AAPL 16.8% vs GOOG 19.3%. 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 AAPL and GOOG

Calmar Ratio: AAPL vs. GOOG

CAGR per worst drawdown

Calmar compares CAGR against the single deepest peak-to-trough loss over the period.

Higher is better

CAGR / max drawdown

Formula

\displaystyle \mathrm{Calmar} = \frac{\mathrm{CAGR}}{|\mathrm{MaxDD}|}

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

Sterling Ratio: AAPL vs. GOOG

Return per average drawdown

Sterling smooths the drawdown penalty by using average drawdown events instead of only the worst one.

Higher is better

excess annual return / average deep drawdown

Formula

\displaystyle \mathrm{Sterling} = \frac{\mathrm{CAGR} - R_f}{\overline{D}_{>10\%}}

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

Treynor Ratio: AAPL vs. GOOG

Excess return per market beta

Treynor divides excess annualized return by beta — the sensitivity of the asset to broad-market moves. The slope shown is each asset’s beta vs SPY.

Higher is better

excess return / market beta

Formula

\displaystyle \mathrm{Treynor} = \frac{\mathbb{E}[R] - R_f}{\beta}

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

Ulcer Index: AAPL vs. GOOG

Drawdown pain

Ulcer Index is a risk index, not a return-over-risk ratio. Lower means smaller and shorter drawdowns.

Lower is better

root-mean-square drawdown

Formula

\displaystyle \mathrm{UI} = \sqrt{\mathbb{E}[D_t^2]}

Ulcer Index captures drawdown depth and duration. Lower Ulcer Index means less drawdown pain. AAPL 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): Apple vs. Google

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.

Definitions: Value at Risk (VaR), Expected Shortfall, skew, kurtosis, and fat tails.

Tail Risk & Distribution Shape: AAPL vs. GOOG (1-Year)

Actual daily return tails

The bars are real daily log-return observations from the article window. Darker bars are observations at or beyond each asset’s 5% VaR cutoff.

Observed returns

VaR marks the 5th percentile loss cutoff; Expected Shortfall averages the observations beyond that cutoff.

Formula

\displaystyle \mathrm{VaR}_{5\%}=Q_{0.05}(r_t),\quad \mathrm{ES}_{5\%}=\mathbb{E}[r_t\mid r_t\le \mathrm{VaR}_{5\%}]

Metric (1-Year)	AAPL	GOOG
5% VaR (daily log return)	-2.09%	-2.54%
5% Expected Shortfall (CVaR)	-3.55% (worst 13 days)	-3.84% (worst 13 days)
Skew	-0.61	0.47
Excess kurtosis	3.65	2.87
2σ tail days (down / up)	6 / 6	5 / 6
Worst day	-7.35% (2026-07-31)	-6.89% (2026-07-23)
Best day	+4.84% (2026-07-02)	+9.97% (2026-04-30)

Downside co-moves (2σ) — 1-Year

Computed on shared dates only (n=250). 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.

Downside co-move map: AAPL vs. GOOG (2σ)

Shared-close daily returns

Dots mark actual downside days: asset-colored dots are one-sided downside moves, and red dots are joint downside days. Grey dots add sampled shared-return context when available. The shaded lower-left zone shows where both AAPL and GOOG crossed their own 2σ downside threshold.

2σ

Rolling correlation sample (shared closes): 221 rolling 30-day values (from 250 shared daily returns).
Annualization (days/year): AAPL: 252 days/year; GOOG: 252 days/year.
Risk-free rate: Uses the 3-month U.S. Treasury yield (FRED: DGS3MO), averaged over each asset’s window:

AAPL: 3.81% over 2025-10-14 → 2026-10-13.

GOOG: 3.81% over 2025-10-14 → 2026-10-13.
Volatility drag (rule of thumb): Estimated from annualized volatility (simple returns). For the log-return framing, see Log returns.

AAPL: ≈ -3.0%/yr
