Berkshire Hathaway's cash holdings increased from $189 billion in the first quarter to $276.9 billion, primarily due to net selling of $75.5 billion worth of stocks. This marks the seventh consecutive quarter in which Berkshire has sold more stocks than it has bought.
Considering the significant scale of Buffett's stock sales and the fact that Berkshire Hathaway only repurchased $345 million of its own stock this quarter, it suggests that Buffett might view the entire market as overvalued.
