After the annual Berkshire Hathaway (NYSE: BRK.A) shareholder conference, investors were eager to learn about Warren Buffett's sales and purchases in Q1.

The updated portfolio shows that Buffett was more active than previously thought. He made some notable additions and reductions in his holdings, with his top five holdings now comprising approximately 75% of his equity portfolio.

Portfolio Overview

Buffett's portfolio now consists of 41 stocks worth over $331.7 billion, a slight decrease from the $351.9 billion in the previous quarter.

This reduction could be a consequence of Buffett's continued addition to cash reserves, which now amount to a record $190 billion. Speculation is rife that this cash reserve is in preparation for the subsequent significant stock acquisition.

Notable Additions

As expected, the Sage of Omaha continued to expand his positions in Liberty Sirius Media (NASDAQ: LSXMA, LSXMK). He added 12,547,944 and 22,277,997 shares for notable changes of 62.09% and 51.56%, respectively.

The difference between the two was the granting of voting rights. Another of Buffett's favorites, Occidental Petroleum (NYSE: OXY), saw its holding increase by 1.77%, or 4,302,324 shares.

The long-awaited hidden stock, for which Buffett received special permission from the SEC to keep secret for the first six months, is Chubb (NYSE: CB). He added 5,823,840 shares, resulting in a total change of 28.97% from the previous quarter.

Reductions

On the flip side, Buffett decided to slightly reduce his holdings in Chevron (NYSE: CVX), Louisiana-Pacific (NYSE: LPX), and Sirius Holdings (NASDAQ: SIRI).

This marks the eighth consecutive quarter in which Buffett's sales outnumber his purchases. This trend indicates the lack of potential investments that meet Buffett's stringent criteria.

"The Sage of Omaha continued to expand his positions in Liberty Sirius Media, adding millions of shares."

Strategic Cash Reserve

Buffett's strategy of bolstering his cash reserves while selectively adding and trimming stock positions aligns with his historical investment philosophy.

The $190 billion cash reserve suggests he is gearing up for future opportunities. Investors and analysts will watch closely to see where Buffett applies his cash next.

In conclusion, Warren Buffett's Q1 portfolio moves demonstrate a blend of strategic additions and cautious reductions. His continued focus on building cash reserves highlights his preparedness for future investment opportunities.
