Performance Overview

Starting with an initial capital of $10,000.00, we purchased shares of BRK-B on 2020-07-06, at a price of $182.72 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 BRK-B had risen to $485.00. While we didn't sell, we can still assess the performance by calculating the current value of the investment: $26,543.34 — a total gain of 165.43%.

This translates into an annualized return of 21.60% over the entire period. This is a very strong return — significantly above what is commonly seen in broad-market performance. It often signals a well-timed entry into a high-growth phase.

Drawdown and Risk

The maximum drawdown recorded during this period was 26.58%. This drawdown began after a peak price of $359.57 on 2022-03-28, and reached its lowest point on 2022-10-12 when the price fell to $264.00. The drawdown lasted for 198 days.

The drawdown was relatively small, suggesting the asset or strategy maintained reasonable stability through market fluctuations. The maximum drawdown lasted over six months, suggesting a sustained downturn or persistent volatility. These periods can shake investor confidence and demand discipline.

The Calmar Ratio — annualized return divided by maximum drawdown — was 0.81, reflecting the tradeoff between return and volatility.

The Calmar Ratio is very strong — significantly better than most long-term investment strategies, indicating efficient risk management.
