Berkshire Hathaway recently filed its second-quarter 13F form, revealing its stock holdings at the end of June.

In late 2016, Warren Buffett started what would become the most profitable investment in his legendary career. Through his company, Berkshire Hathaway Corp. (BRK.A), he began accumulating shares in Apple Inc.

Interestingly, according to reports, Fischbeck's move wasn't necessarily based on the Buffett team's entrance into the stock.

Buffett’s entry signals that these issues may prove to be temporary, helping fuel the sharp rebound.
