Backtest: Buy and Hold BA (The Boeing Company)

This analysis evaluates a buy-and-hold strategy over the past 63 years, providing a historical perspective on BA's performance from 1962-01-03 to 2025-07-03.

Note: This simulation uses adjusted close prices, meaning all historical prices have been retroactively adjusted for splits and dividends. To achieve similar results in practice, you would need to reinvest all dividends automatically as they are paid.

Performance Overview

Starting with an initial capital of $10,000.00, we purchased shares of BA on 1962-01-03, at a price of $0.19 per share (adjusted for splits and dividends). No trading, no adjustments — just a simple buy-and-hold approach.

We held the position continuously through every market twist and turn, never selling. As of 2025-07-03, the price of BA had risen to $215.92. While we didn't sell, we can still assess the performance by calculating the current value of the investment: $11,308,805.72 — a total gain of 112,988.06%.

This translates into an annualized return of 11.71% over the entire period. This return is moderately above long-term averages. It reflects solid long-term performance and an effective strategy.

Drawdown and Risk

The maximum drawdown recorded during this period was 88.43%. This drawdown began after a peak price of $1.03 on 1967-08-03, and reached its lowest point on 1970-07-07 when the price fell to $0.12. The drawdown lasted for 1069 days.

The drawdown was very large, indicating high sensitivity to adverse market conditions. Strategies with this profile may offer strong upside but require enduring deep declines. The maximum drawdown lasted over two years, reflecting a prolonged period of market weakness or asset-specific decline. Recovery from such drawdowns can be psychologically and financially difficult.

The Calmar Ratio — annualized return divided by maximum drawdown — was 0.13, reflecting the tradeoff between return and volatility.

The return-to-risk efficiency is weak — drawdowns were relatively large compared to the returns achieved.
