After filingAt quarter endBenchmark · S&P 500
After filing — buys the holdings only once the filing is public — about 45 days after the quarter ends. The path someone could actually have taken.
At quarter end — pretends the same holdings were bought on the last day of the quarter, before anyone could have known them. Not possible in reality — shown dashed for comparison only.
Benchmark — S&P 500 (SPY) total return over the same window — what doing nothing but holding the market would earn.

Hypothetical backtest — not a real trading record. Simulated on public data from 2013-08: each position is bought only after the filing became public (using no information unavailable at the time), with trading costs deducted, on a total-return basis. Past performance does not predict future results.

About
Warren Buffett

Warren Buffett has run Berkshire Hathaway since 1965, buying outstanding businesses at fair prices and holding them for the long haul — turning that value discipline into one of the most studied long-term records in history. He transformed a failing textile mill into a colossal insurance-and-industrial conglomerate, and his decades of compounding are treated as canon.

The replication is built from public filings: ~45-day lag, US long stock positions only; replication returns are not the fund’s real returns, and the manager may have traded since.
Past / backtested performance does not predict the future. Data and calculations may contain errors; we correct them when found. Masterfolio is an information service / publisher, not an investment adviser. Fund and manager names refer to their public filings only; no affiliation or endorsement.
