Berkshire Hathaway’s continued sales of Apple shares in the third quarter left the conglomerate’s stake at a fraction of its size at the start of the year.

Berkshire cut its holdings in the iPhone maker by roughly 25% in the period, after slashing it by almost half in the second quarter. Apple’s shares gained 10.6% in the period ended Sept. 30.

Warren Buffett hinted at Berkshire’s annual meeting in May that the sales of Apple in the first quarter were partly motivated by tax implications, and that the tech giant would remain the largest investment for the Omaha, Nebraska-based conglomerate.
