◆ The Signal
30-second read
What happened
On October 29, 2026 Alphabet fell 12.64% and Amazon 4.25%, while the S&P 500 (SPY proxy) fell 0.38% and closed 1.2% below its high. Alphabet's 20-day realised volatility was 49.1% annualised; the index's was 10.1%.
Why
A loss and the gain needed to undo it are not symmetric: recovering from −L requires 1 ÷ (1 − L) − 1. A 0.38% loss needs 0.38% back; a 12.64% loss needs 14.47%; a 29.5% drawdown needs 41.8%. How much of that lands on a household depends on position size.
