Berkshire Hathaway Inc. (NYSE: BRK-A) has released its public equity holdings as of December 31, 2016, and the number of changes in the equity portfolio were nothing short of massive. What investors are going to take away from this report is that this is the public portfolio of Warren Buffett stocks for 2017.

24/7 Wall St. has tracked Warren Buffett and Berkshire Hathaway’s investments over the years, and there were many surprises seen from the end of 2016 versus a year earlier. Some of Buffett’s changes have been substantial.

Warren Buffett and his team of portfolio managers listed some 148 positions worth a whopping $147.9 billion in equities in the official Form 13F filing with the U.S. Securities and Exchange Commission. This compared to $128.8 billion as of the end of the third quarter of 2016 and $115.46 billion as of December 31.

It is important to understand that some changes are made by Buffett himself, with 14 sub-entities of Berkshire Hathaway in prior filings. Other changes may have come from the likes of newer portfolio managers Ted Weschler and Todd Combs. It appears as though the Buffett portfolio managers have been given much larger investing amounts.

If there is one key takeaway for the 2017 stocks, it would be that this was one of the largest changes we have seen in years. New stakes were added and other stakes were grown. Other stakes were cleaned out or decreased.

24/7 Wall St. has known for years now that four stocks make up the lion’s share of the Berkshire Hathaway public holdings. One issue to consider is that Berkshire Hathaway’s public equity investments are held in other instruments outside of common stocks, which are not counted in this 13F filing. Berkshire Hathaway invested $3 billion in 2009 into preferred shares of Dow Chemical, and it invested $5 billion for preferred shares and warrants in Bank of America back in 2011.

Wells Fargo & Co. (NYSE: WFC) was listed as 479,704,270 shares, the same stake as seen in September. As a reminder, it has been documented that Buffett has filed to be allowed to increase his stake north of the 10% threshold with the SEC, and Buffett did not sell any Wells Fargo shares after the account-opening scandal and during the Stumpf exit. International Business Machines Corp. (NYSE: IBM) was listed as 81.232 million shares at the end of 2016, the same as in September, June and March. Buffett’s Big Blue stake has been raised previously. Three more giant stakes that remained static were as follows:

• Coca-Cola Co. (NYSE: KO) was the exact same stake of 400 million shares. This position has remained static, and Buffett has defended his stake for years.
• American Express Co. (NYSE: AXP) was the same 151.6 million or so shares, a position that remains perpetually static. We have said this before, but Buffett has owned Amex for so long it may be cheaper for him to just hold rather than pay capital gains.
• Kraft Heinz Co. (NYSE: KHC) was listed as the same 325,634,818 shares and was previously a stake from the 3G Capital deal. The value in the portfolio was a whopping $28.4 billion, but that was down from the prior quarter. Please note that the 10-Q filing for September 30 said that the carrying value of this investment was down to $15.711 billion as it had recorded a noncash pretax holding gain of approximately $6.8 billion in 2015.

Apple Inc. (NASDAQ: AAPL) was a vastly larger stake at the end of the fourth quarter of 2016 when compared with the third quarter. The new Apple stake is some 57,359,652 shares, up from just 15.227 million in the prior quarter. Apple shares just hit a new all-time high on this same day. This may seem odd considering that Buffett is good friends with Bill Gates, but that was certainly a position taken by Weschler or Combs.

Another major change that had been seen was a big bet on the airline sector. This was divulged late in 2016 and was a noted departure by Buffett’s portfolio managers rather than by Buffett himself. That position was recently shown to have been wildly profitable. These larger airline stakes were shown as follows:

• American Airlines Group Inc. (NASDAQ: AAL) was a new stake last quarter, but that stake rose to 45.54 million shares from 21.77 million shares.
• United Continental Holdings Inc. (NYSE: UAL) was a much larger stake of 28.95 million shares at the end of 2016. This had been listed as a new stake of 4.533 million shares at the end of September.
• Delta Air Lines Inc. (NYSE: DAL) was listed as a new stake of 60.02 million shares. This is massively higher than the prior stake of 6.333 million shares.
• Southwest Airlines Co. (NYSE: LUV) was also a stake that was taken at the end of the third quarter, but it was unknown about the actual size because Buffett hadn’t disclosed that stake. The Southwest stake at the end of 2016 was just over 43.2 million shares.

Phillips 66 (NYSE: PSX) was the same 80.689 million shares at the end of 2016 versus the end of September, but the stake was a Buffett pick and had been raised from 78.782 million shares as of June 30 and 75.55 million share stake in March of 2016. As a reminder, Phillips 66 had previously had been classified as an elimination in 2015 and then was shown after Buffett got the stake classified with the SEC as confidential.
