The Mac Observer:

Warren Buffett bought some 5.41 million shares of Apple during the June quarter, according to regulatory filings with the Securities and Exchange Commission (SEC). The investment cost more than half a billion dollars, and represents a 55% increase in Berkshire Hathaway’s stake in Apple.

Mr. Buffett’s position puts him at odds with some other big investors. Reuters noted that David Tepper and Leon Cooperman recently began paring back on their position in $AAPL. Hedge funds have also reduced their positions in Apple as Apple faced its first year-over-year decrease in revenues in 13 years.

To be more accurate, Buffett’s company, Berkshire Hathaway, made the purchase. It makes a difference because, while Buffet has been personally critical of technology stocks, Berkshire Hathaway has recently hired a couple of tech fund managers who are much more bullish on Apple. That’s likely what happened here.
