Berkshire acquired 4.175 million shares of Red Hat worth $733 million, according to filings. The investment company also picked up new stakes in Suncor Energy , purchasing 10.75 million shares, and bought a stake in StoneCo Ltd., described as the PayPal of Brazil by some, adding 14.16 million shares, filings show. Meanwhile, the influential investor shed 2.89 million shares of Apple , reducing his position in the iPhone maker by about 1%, according to filings. The investment company maintains 249,589,329 million shares of Apple worth about $39.4 billion, making up 21.5% of Berkshire’s holdings, down from 25.8%, according to data from WhaleWisdom. Meanwhile, Buffett’s firm slashed his stake in Phillips 66 , reducing it by 22%, or 3.5 million shares, and cutting his holdings in the parent company of United Airlines by 15%, or by about 4 million shares. Berkshire also notably unloaded its entire stake in Oracle Corp. , a little over 41 million shares, the 13F filing shows. Large investors must disclose long stock positions held at the end of a quarter 45 days later in a 13F filing with the SEC, which means such filings are merely a snapshot of an investor holdings at a given point. Berkshire Class A and B shares are down by about 0.7% so far in 2019, compared with a 9.1% year-to-date gain for the Dow Jones Industrial Average and a 9.5% gain for the S&P 500 index thus far in 2018, according to FactSet data. The technology-laden Nasdaq Composite Index has gained 11.9% so far this year.
