They don’t call Warren Buffett the Oracle of Omaha for nothing.

Buffett-led Berkshire Hathaway increased its stake in Apple by nearly 5 percent during the second quarter, regulatory filings show.

While the exact dates of the conglomerate’s purchases are unknown, Apple’s stock has soared 20.5 percent since the start of the second quarter and 13 percent in the third quarter to $209.75.

Apple has also since become the first company whose market cap crossed $1 trillion, beating Amazon and Google-parent company Alphabet to the punch.

While Buffett was buying up Apple, beleaguered hedge fund manager David Einhorn sold more than 75 percent of his stake in the tech giant during the second quarter, according to regulatory filings.

Einhorn’s Greenlight Capital is down 18.3 percent for the year, the hedgie revealed in a letter to investors last month.

“Right now, the market is telling us we are wrong, wrong, wrong about nearly everything,” Einhorn said in last month’s letter.
