This Dirt-Cheap Stock Still Looks Likes Warren Buffett's Favorite Buy in 2020

A week ago, investors were looking forward to the release of Berkshire Hathaway 's (NYSE: BRK.B) (NYSE: BRK.A) latest 13F filing with the Securities and Exchange Commission. The quarterly report reveals changes to the company's stock portfolio, giving investors insight into what famed investor and Berkshire CEO Warren Buffett has been buying and selling recently.

Investors were particularly eager to see Berkshire's latest 13F filing because it covers a period in which stocks crashed. The overall market is still down more than 15% from its all-time high earlier this year. Berkshire's stock purchases during the period, therefore, could potentially reveal great buying opportunities for investors while the market is still down sharply.

However, it turns out there weren't any meaningful purchases during the quarter other than the one stock the company had already revealed that it spent nearly $1.6 billion on: its own Berkshire Hathaway stock.
