Omaha, NE - In a recent filing with the Securities and Exchange Commission, Berkshire Hathaway, led by renowned investor Warren Buffett, revealed significant changes in its stock portfolio. The filing disclosed that Berkshire had sold over 389 million shares of tech giant Apple (AAPL) during the second quarter of this year. Despite this substantial reduction, Berkshire still holds a significant position in Apple, with approximately 400 million shares remaining as its largest stock holding.

The filing also highlighted other notable sales, such as Berkshire's reduction in investments in Bank of America, Chevron, Capital One, Floor & Decor Holdings, T-Mobile, and Louisiana Pacific. Additionally, Berkshire sold its nearly $1 billion stake in Snowflake. These sales have contributed to Berkshire's cash pile reaching an unprecedented level of $277 billion.

On a positive note, Berkshire did increase its investments in Chubb and Occidental Petroleum. Furthermore, smaller new investments were revealed in aerospace parts maker Heico Corp. and cosmetics retailer Ulta Beauty.

The quarterly filings do not specify which investment decisions were made by Warren Buffett and which were made by Berkshire's other investment managers. However, Buffett typically handles Berkshire's largest investments, worth over $1 billion, making his actions closely watched by many investors due to his successful track record over the years.

Berkshire Hathaway's diverse portfolio includes not only its massive $300 billion stock portfolio but also several major insurance companies, such as Geico and BNSF Railway, one of the nation's largest railroads. The conglomerate also boasts a collection of utilities and manufacturing and retail companies, with well-known brands like Dairy Queen, Helzberg Diamonds, and NetJets under its umbrella.

With these significant changes in Berkshire's portfolio, investors and market observers will be closely monitoring how these shifts may impact the company's overall performance and future investment strategies.
