Berkshire has been a net seller of stocks for six consecutive quarters, signaling a strategic pivot in its investment approach.

Despite the reduction in stock holdings, Berkshire Hathaway reported a 15% increase in second-quarter operating profit, reaching $11.6 billion, largely driven by its insurance businesses.

The increase in cash reserves may indicate Buffett's concerns about the U.S. economy, as Berkshire is often viewed as a proxy for economic health.

Despite these challenges, Apple remains the world's most valuable company, boasting a market capitalization of $3.35 trillion.

While Buffett has previously expressed confidence in Apple, his recent selling actions raise questions about the company's growth prospects and valuation.

Earlier this year, Buffett sold 115 million Apple shares for cash, further indicating a strategic shift in his investment philosophy.

Analysts suggest that Buffett's actions reflect prudent portfolio management in light of recent economic uncertainties and disappointing tech sector earnings.

Warren Buffett's Berkshire Hathaway has significantly reduced its stake in Apple, cutting it by approximately half, which is now valued at $84.2 billion, according to an SEC filing.

At the end of the second quarter, Berkshire's investment in Apple was valued at $84.2 billion, down from $135.4 billion at the end of the first quarter, reflecting a decrease of 390 million shares.

This recent sale marks the third consecutive quarter of substantial stock sales by Berkshire Hathaway, indicating a potential shift in investment strategy.

Buffett's selling spree includes significant amounts of stock in companies such as Bank of America and BYD, raising concerns about an overheated market.

As a result of these stock sales, Berkshire Hathaway's cash reserves have surged to nearly $277 billion, reflecting Buffett's cautious approach to the current market conditions.
