Berkshire Hathaway's regulatory filings don't reveal the full story.

Which stocks does Warren Buffett like the most? Obviously, Berkshire Hathaway (BRK.A 0.68%) (BRK.B 0.99%) deserves to be at the top of the list. Most of Buffett's personal net worth is invested in the company.

There's also a good case to be made that Apple (AAPL 1.98%), Bank of America (BAC 1.96%), and Chevron (CVX 0.86%) should be on the list of Buffett's favorite stocks. If you look at Berkshire's regulatory filings, they rank as the conglomerate's top three holdings. But those filings don't tell the full story.
