Berkshire Hathaway's cash pile swelled to a record of nearly $277 billion in the second quarter, up significantly from the previous record of $189 billion. This came after Warren Buffett sold nearly half his stake in Apple and over $75 billion in stocks. Berkshire's operating earnings were up 15% from the second quarter, boosted by auto insurer Geico. Berkshire repurchased just $345 million of its own stock, down from $2 billion in each of the prior two quarters.
