Here is the year-to-date winners and losers list of the Superinvestor portfolio, as defined by Dataroma.
The Large portfolio includes the stocks held by all of the superinvestors, and the Small portfolio includes only the holdings of Berkshire Hathaway, Markel, Sequoia and SQ Advisors.
The date at the top of the spreadsheet shows when the sort was run and not necessarily the date of the latest stock price.
I will set this up to run on Friday evenings (it should be fully automatic). These tables are based on the closing prices.
This was run on Thursday, Feb 23, because I am out Friday.
