Warren Buffett Just Sold These 8 Stocks, One of Which Remains a Phenomenal Bargain (and a Top Holding of Mine)
The Oracle of Omaha has been a big-time seller of stocks for 10 consecutive quarters -- but there's one sale he may regret.

There's arguably no announcement that's packed with more information and clues about the stock market and the companies powering it higher or lower than quarterly Form 13F filings with the Securities and Exchange Commission (SEC).
13Fs are filed no later than 45 calendar days following the end to a quarter by institutional investors with at least $100 million in assets under management. These filings tell investors precisely which stocks and exchange-traded funds (ETFs) Wall Street's most prominent money managers purchased and sold in the latest quarter (the first quarter, in this case).
May 15 marked the deadline for 13Fs to be filed with the SEC, and no filing is ever more anticipated than the one from Berkshire Hathaway's (NYSE: BRK.A)(NYSE: BRK.B) Warren Buffett. Since taking over as CEO 60 years ago, the aptly nicknamed "Oracle of Omaha" has overseen a cumulative return in his company's Class A shares of better than 6,230,000%, as of the closing bell on May 16. Investors line up at the chance to ride Buffett's coattails to significant gains.
