Warren Buffett's Berkshire Hathaway invested $1.6 billion in UnitedHealth Group stock last quarter, acquiring over 5 million shares. This significant move, made close to Buffett's retirement, caused UnitedHealth's stock to surge. The investment comes as Berkshire simultaneously reduced its Apple holdings and added positions in several other companies, including homebuilders and a steel producer. Berkshire's overall stock sales totaled $6.9 billion last quarter, increasing its cash reserves to over $344 billion.
