How to Read a Berkshire Hathaway Portfolio Snapshot

People often search for “Warren Buffett’s portfolio” and find a list of Berkshire Hathaway holdings. That list can be a useful starting point for a historical replay, but the label needs to stay precise.

Equity Replay’s Berkshire example is a normalized snapshot of selected disclosed Berkshire positions. It is not Buffett’s personal brokerage account, a complete list of Berkshire’s assets, or a live view of ownership.

What a filing gives you

A public filing gives you a reporting date and disclosed information about the securities included in that filing. It lets you review what was visible at that point in time.

To make the example comparable with a user-created allocation, selected positions can be converted into percentages that total 100%. That normalization is useful for charting, but it is an assumption made for the replay. It does not change the original disclosure.

What a filing does not give you

A filing does not automatically tell you every asset held by an organization, what someone owns personally, the exact moment a position changed, or the reason for a transaction. It may also represent a particular reporting period rather than today’s holdings.

That is why the source, date, and disclosure note belong next to the chart. A careful title says “Berkshire snapshot” or “disclosure replay,” not “complete Buffett portfolio.”

How to explore the example

Open the Berkshire replay and check the four things that make the comparison understandable:

• The date attached to the disclosure.
• Which positions were included.
• How the selected positions were normalized.
• What the historical calculation excludes.

The chart applies the normalized allocation once at the beginning of the selected range. It does not model interim trades, deposits, withdrawals, or rebalancing. It shows how that defined mix moved across historical close prices.

You can open the Berkshire snapshot, then read how the historical replay is calculated.
