It'd be hard to argue that Warren Buffett is not the greatest investor of all time, we can all agree that he is. With a giant portfolio he managed and because of financial regulations, he has to disclose his portfolio to the public which means all US investors get to look at how the greatest investing mind is investing in this day and age.

So what Warren Buffett has been buying and selling in Q4 of 2020 and what his stock portfolio looks like as we drift further into 2021, according to 13F filings publicly released for Q4 2020, we want to break everything down piece by piece and show you exact stocks that Buffet owns to navigate these weird market conditions that we are currently in.

Stock 1: AAPL

Warren Buffett's largest position by far with his investing company Berkshire Hathaway is $Apple Inc(AAPL.US)$. The shares of the world's largest tech giant rallied over 350% since Berkshire first initiated a position in Apple in 2016. Apple makes up 43.62% of the entire stock portfolio and he owns 887.1 million shares of the company altogether which's worth 117.7  billion USD, that's a lot of money in one stock even on Buffett's terms. 

 I don't think of Apple as a stock. I think of it as our third business. - Buffett

Many people already know generally what the company does, let's show you a bit deeper though. So the main thing that the company sells is obviously the iPhone, one of the most popular selling phones in all of history, based on the Q4 2020 earnings result, iPhone makes up 40.9% of their revenue. 

And they also sell iMac and the iPad which makes up 14% and 10.5% of the revenue respectively. Then of course, you've got the slightly newer segments which is the wearables and home accessories that make up 12.2% and lastly you've got the services side to their business, so that's things like iTunes, App store, Appl music, Apple pay and all of that makes up 22.5% of the revenue. 

So that gives a bit of an idea of Apple the company as a whole. Let's take a quick look at the stock now, so this is one of the biggest companies in the world right now it's valued at over two trillion dollars, that is big the price of an individual stock if you are looking to buy is $137 dollars a share with earnings of 3.28, the stock has rallied very nicely over the past couple of years, it's gone from $24.16 to over five times the amount today. 

Stock 2: Bank of America

Moving on to his second-largest position that's $Bank of America Corporation(BAC.US)$，which Buffett invested in 2011, one of the biggest banks in America and it makes up 11.35% of his entire stock portfolio that valued at over 30.6 billion dollars. 

So Bank of America what do they do? They help with loan banking services, investing asset management and other financial-related roles, a very complicated business but Buffett knows them well price-wise. 

They are affordable to pretty much any investor unless you are broke, they sell for $40 a share right now and in return, they generate earnings of 1.87 dollars a share that gives them quite a low PE ratio in this market anyway of just 21.3. There is also another nice thing about the stock is they pay a bit of a dividend an annual yield of 1.8% which is pretty decent. This is an interesting position for Buffett as a lot of you know he's been into banking stocks for a long time, however, in these market conditions the banking business model will be tested and time will tell if this is a smart investment to hold.

Stock 3: Coca-Cola 

The "Oracle of Omaha" has believed in $Coca-Cola Company(KO.US)$ since 1987, 8.13% of Berkshire's portfolio is in the company Coca-Cola. It's one of the best drinks of all time, Buffet owns exactly 400 million shares worth 21.9 billion dollars that's a lot of money again.

A pattern that you will start to notice with a lot of Buffett's main stocks is they operate simple business models. Coca-Cola you don't have to be Einstein to understand their model, they distribute drinks all around the world and they sell them at various outlets. 

Some of their billion-dollar brands include Coke obviously Fanta, Sprite, Schweppes, Simply Orange, Smart Water and a range of others. And one of the things that stands out about coca-cola stock is their dividend they pay a dividend yield of 3.08% and the great thing about this is they've increased it for 58 consecutive years, making it one of the safest dividend-paying stocks.

Stock 4: American Express

$American Express Co(AXP.US)$ has been a Buffett holding since the 1960s, it is not a bank but it's a financial services company quite old founded in 1850. One of the patterns that you should notice while going through Buffett stocks is that he loves financially oriented companies, this particular one American Express makes up 6.79% of his portfolio over at Berkshire Hathaway, he owns 151 million shares of them with a total value of 18.3 billion dollars. 

Not too much to say on this company, the buy thesis with American Express is really similar to Banks of America. They're obviously known for the charge card credit card and travelers check businesses, one of the more fascinating things about American Express is its ability to court more affluent clientele. Dating back decades, an American Express gold or platinum card still holds a sort of allure to consumers that few other credit card brands bring to the table. The thing is, affluent cardholders are less likely to be shaken by minor economic disruptions. In theory, this should help American Express navigate its way through contractions and recessions better than most lenders.

The stock has had an interesting couple of years up until 2020 they were going great up over 150% from the start of 2016 and then, of course, we had those rough economic times the stock got hit hard but has rebounded relatively nicely. 

Stock 5: Kraft Heinz 

$The Kraft Heinz Co(KHC.US)$ this is another company that has had tough times over the past couple of years. It's a big position of course for Buffett, he owns 325.6 million shares worth a total of 11.2 billion dollars, and that's 4.18% of his portfolio.

So craft Heinz is a food company, it's actually the third-largest food and beverage company in North America with 26.2 billion dollars in annual sales. If we take a look they've got some big-name brands over here, Wattie's, Kool-Aid, Jell-O, Philadelphia. 

It's no wonder they've sold 26 billion dollars worth of items, however, they have been struggling as a stock at one point in time, they were selling for over 90 dollars a share and since then they've gone down dramatically and the reason for that is poor earnings, as you can see they've lacked innovation with their products and the margins made have not been good. 

So the price is down big however, we do have some investors saying that this is an opportunity, they pay a really nice dividend right now, they are going for a cheap price and the business model is fine so that's up to you to decide if it's a buy or not.

Stock 6: Verizon Communications

The new buyers that warren Buffett has completed in Q4 2020, the first one is a big buy and it's in $Verizon Communications Inc(VZ.US)$. Warren Buffett's Berkshire Hathaway disclosed a stake that was worth more than 8.6 billion dollars in Verizon, and that makes up 3.19% of his entire portfolio. 

So of course Verizon Communications is a massive U.S. telecommunications company. They offer wireless internet TV, phone services. They've got 2330 retail stores and they are actually the second-largest telecommunications company by revenue behind $AT&T Inc(T.US)$, So interestingly buffet is getting more exposure to the telecommunications sector.

Stock 7&8: Moody's & U.S. Bancorp 

Next two we are going to group together, they are both financial stocks, not the most interesting to talk about, so $Moody's Corporation(MCO.US)$ corporation that makes up 2.65% of the portfolio and us $U.S. Bancorp(USB.US)$ that makes up 2.26%.

So again with these banking stocks it's kind of like the double-edged sword, prices are very cheap relative to other stocks however their business model is going to be tested in these tough economic conditions, risk-reward that's what investing all comes down to. 

Stock 9: Chevron Corporation

Berkshire Hathaway announced a 4.1 billion stake in $Chevron Corp(CVX.US)$ which makes up 1.52% of his portfolio.

Chevron is one of the leading integrated oil and gas companies in the United States. As a company with a 140-year history, Chevron is a dividend aristocrat, having delivered 33 years of consecutive dividends. The consistent dividend is of course backed by a steady stream of cash flows, but most importantly, it is also backed by what can be considered a conservative balance sheet by industry standards. 

As being a fully integrated oil and gas company, Chevron has two layers of diversification. Firstly, the company actually produces at least two "products", oil and gas. Secondly, the economy is involved in all the different stages of energy production. From extraction to transportation to sale. Fully integrated companies are considered to be less risky and volatile for the most time, so that's probably the reasons why Warren Buffett's Berkshire Hathaway owns such a portion of this stock.  

Stock 10: Dvita healthcare

$DaVita Inc.(DVA.US)$ is Buffet's tenth-largest position as we are starting to get into the very small amounts, it makes up just 1.4% of Buffett's entire portfolio, Berkshire owns 36 million shares of this stock worth 4 billion dollars. 

It might be the smart move from buffets to expose his portfolio to a bit of health care, healthcare is a sector that does better than most in recession and it does fine in pretty much all economic conditions, why, because people still need health care no matter what the economy is doing.

The stock has done well for Buffett over the years, he bought it back in 2012 and since then it's gone up a nice 100% as of right now the stock sells for just over a hundred dollars a share with a reasonable PE ratio of 18. 

To sum up

So that's the 10 biggest stock positions, these make up 85.09% of his entire portfolio, rest of the stocks owned are very small positions, the most of them are under 1 % and these include stocks like $AbbVie Inc(ABBV.US)$ the pharmaceutical company, $Visa Inc(V.US)$,  $Amazon.Com Inc(AMZN.US)$, the e-commerce company $Snowflake Inc(SNOW.US)$ and a range of others, but the other thing we want to mention is he's got a big cash pile on him as well over at Berkshire Hathaway. 

Berkshire Hathaway has 138.29 million dollars of cash on them, just waiting to be deployed and waiting for stocks to get cheaper before they deploy that cash and make some big moves in the market. Either way, it's such a privilege that we can see into the portfolio of one of the greatest investing ambassadors of all time.
