2026-Q1 Berkshire Hathaway Inc 13F Filing: Berkshire triples GOOGL stake to 5.93%

Every quarter, large institutional money managers must file a 13F form with the SEC, revealing their US stock holdings. This walkthrough of Berkshire Hathaway's latest filing shows you exactly what data matters and how to interpret the trading decisions behind the numbers.

1. What a 13F Filing Discloses
   A 13F is a snapshot of what a manager owned at the end of the quarter. It lists each position's market value and share count. From this filing, we see Berkshire's portfolio shrank in diversity: holdings fell from 42 to 29, and the turnover ratio jumped from 0.093 to 0.2359, meaning the firm actively reshuffled a much larger fraction of its assets.

2. Spotting New vs. Existing Positions
   The action field tells you exactly what the manager did. "new_buy" means a completely new position bought during the quarter. You see this for Delta Air Lines (DAL), Alphabet voting shares (GOOG), and Macy's (M). DAL now makes up 1.01% of the portfolio, while GOOG represents 0.39%. In contrast, an "add" means they added to an existing holding, as with GOOGL, NYT, and LEN.

3. Understanding a Trim vs. a Full Exit
   "Trim" means the manager sold some shares but kept the position. BAC was trimmed from 10.38% to 9.52%, reducing its value by -$3.41B. "Sold_out" means they sold everything — examples include Visa (V) and Mastercard (MA).
   Important nuance: a trim does not always produce a lower dollar value. DVA shows a trim in shares, yet its value rose by +$1.02B. The filing note explains: "shares were trimmed (real selling), but the dollar value rose because the stock price gained more than the trimmed shares were worth — NOT a buy." Always check the price movement if value and action run opposite directions.

4. The Scale of Exits
   Berkshire closed out more than a dozen positions this quarter. Among the notable sold-out names are Amazon (AMZN), UnitedHealth (UNH), Domino's Pizza (DPZ), and Charter Communications (CHTR). As a result, the financials weight dropped from 43.07% to 36.42%, and energy rose from 11.28% to 13.26%.

5. Overall Portfolio Strategy
   The combined picture shows a manager making concentrated bets. The GOOGL position ballooned from 2.04% to 5.93% of the portfolio, a tripling in weight. Technology and communication services together now account for almost 24% of assets. At the same time, the number of holdings fell by nearly a third, and the HHI (Herfindahl index) slipped from 0.1267 to 0.1185, confirming modest de‑concentration. Berkshire is focusing on its highest conviction ideas.
