Warren Buffet's 13F report is undoubtedly one of the most highly-anticipated filings each quarter. Alongside other major investors, Buffet and his behemoth conglomerate Berkshire Hathaway report their holdings at the end of each quarter to the SEC through a filing known as a 13F. Considering that Buffett is one of the wealthiest and most highly respected investors alive today, outsiders with an interest in investing routinely look to him for ideas on how to move their money around. Now, with the 13Fs from the second quarter of the year newly available to the public, analysts are poring over the billionaire's recent investment decisions.

Berkshire Adds Position in Synchrony, Builds Bank of New York Mellon

At least two major shifts occurred in Buffett's holdings over the course of Q2 of this year, according to the 13F and reported on by USA Today. First, Buffett built up a new position in Synchrony Financial (SYF), purchasing a massive stake of 17.46 million shares over the course of April to June. Based on the closing price of $29.64 per share as of yesterday afternoon, this means that Berkshire's position as of June 30 would be worth $518 million today. On news that Buffett had invested, shares of Synchrony climbed by about 4.5% in after-hours trading. Synchrony is known for providing private label credit cards and was formerly part of GE Capital before spinning off toward the end of 2015.

The second major purchase in Berkshire's portfolio is an addition to an older position. Buffett reportedly increased his holdings of Bank of New York Mellon (BK) by more than 50%. Berkshire bought more than 17 million shares of BK stock, an increase of 52% from its 33.01 million shares at the end of the first quarter.

Positions in IBM, GE Reduced or Eliminated

Buffett also trimmed back or eliminated some of his holdings. His company dumped the remaining 10.6 million shares of General Electric (GE) over the course of last quarter. The billionaire also trimmed down his position in IBM (IBM), dropping his total share count by nearly 10.5 million shares. As of June 30, Buffett held 54.08 million shares of the company.

Buffett is famous for selecting a small number of companies and investing in them for the long term. His holdings in Apple, Coca-Cola, and Wells Fargo are famous for their size and for the length of time he has owned them. It seems that there were no major changes to these cornerstone positions in Berkshire's portfolio for the second quarter of the year. Nonetheless, it's important to keep in mind that Buffett's 13F shows his holdings as of June 30, and that he may have altered his portfolio in small or large ways since that time.
