Berkshire’s 13F filing on 11/14/23 asked to keep one or more of its equity holdings confidential.

Answers are open to add.

What is the “secret” acquisition? Can resolve to one or more new stocks.

The answer will be resolved based on media consensus after a company (or companies) have been discussed by Buffett and/or Berkshire as new acquisitions.

“Other” will resolve only if no correct name was guessed.
