Prediction: Warren Buffett Will Reveal an Increase in This Massive Berkshire Hathaway Holding on May 3
This high-yield investment could continue to make up a significant portion of Berkshire's portfolio.

Roughly 40,000 Berkshire Hathaway (NYSE: BRK.A) (NYSE: BRK.B) shareholders will descend upon Omaha, Nebraska the first weekend in May. The annual shareholder meeting hosted by CEO Warren Buffett gives investors an opportunity to ask the Oracle of Omaha questions about Berkshire Hathaway and the stock market in general.
But before the question and answer portion, which lasts hours, Buffett likes to discuss the company's first-quarter financial results. I expect those financial statements will disclose an increase in one of Buffett's biggest investment holdings for Berkshire Hathaway. And he'll likely field several questions about it to give investors more insight on May 3.
