Warren Buffett’s Berkshire Hathaway Inc. boosted its investments in Goldman Sachs Group Inc. and Israel’s Teva Pharmaceutical Industries Ltd. during the second quarter and confirmed it has expanded its already huge bet on iPhone maker Apple Inc. 

The changes were disclosed on Tuesday in a regulatory filing detailing Berkshire’s U.S.-listed stock holdings as of June 30. 

Investors closely watch Berkshire’s quarterly stock listings for signs about where Buffett and his investment managers Todd Combs and Ted Weschler might see value. 

The filings do not say which managers bought which stocks. Berkshire spent $6.08 billion on equities in the quarter. 

Berkshire boosted its Goldman stake by 21 percent, owning roughly 13.3 million shares worth $2.92 billion on June 30, up from 11 million shares on March 31. 

That stake had its origins in a profitable investment in Goldman preferred stock that Berkshire made during the 2008 financial crisis. 

The Teva stake grew 7 percent to 43.25 million American depositary receipts worth about $1.05 billion. Teva’s ADRs rose 1.2 percent after market hours. 

Berkshire also said its Apple stake swelled to about 252 million shares worth close to $47 billion, up 5 percent from 239.6 million shares three months earlier. 

Berkshire owns roughly 5 percent of Apple, whose market value surpassed $1 trillion last week.
