Who Is Warren Buffett and What Is His Investment Strategy?

Saying that Warren Buffet is arguably the most successful investor ever would sound obvious for basically everyone in the world of investment. In fact, his economics and investing advice are still adopted in different strategies. But who exactly is Warren Buffett?

Buffett is one of the wealthiest people in the world. He made his fortune in the stock market and, since 1970, he has been the largest shareholder of Berkshire Hathaway, a conglomerate holding company.

The research of his investment decisions provides a better understanding of its basis and how to follow it.

The Long-Term Should Be Your Goal

To Warren Buffet, day-to-day stocks do not really matter. At all. Buffett prefers the buy-and-hold strategy, a passive strategy that avoids being influenced by short-term oscillations. This may lead to a stable portfolio and can have a better value at the stocks owned in the long-term. This strategy believes that the market will favor undervalued quality stocks over time, so there is no reason to panic because of the price variation from one day to another.

How To Find Undervalued Stocks

To Warren Buffet, some factors need to be analyzed in the company before deciding if it is a good stock to invest or not. For instance, find the return on equity (ROE) of a company can be a good measure, but it is not enough. The quality of the company can not be seen only in the past ROE but analyzing the past 10 years.

Also, the strategy considers company debt and profit margin. By observing the debt-to-equity ratio (D/E) and the division between net income and net sale, respectively, we can analyze the two factors mentioned above.

Additionally, other factors can be important. Buffett already said that he does not understand completely the mechanics of new technology companies and this impact on his decision to invest or not in the company. Companies that rely solely on commodities are also avoidable in that decision.

Finally, the most important: the company value. By analyzing all those factors, Buffett is able to identify if the company’s intrinsic value and compare to its liquidation value. If the intrinsic value is higher than the liquidation value, that is the opportunity to invest.

Which Companies Are We Talking About?

Honestly, that is a million-dollar question. Since the Coronavirus pandemic, stocks all around the world of several different areas plunged. Considering Buffet’s strategy, this may be the best opportunity to find its main point: the undervalued stocks.

One of the best examples right now is Apple stock (AAPL). Since Buffet’s Berkshire Hathaway is one of Apple’s shareholders, it is fair to say that the giant tech fits in his strategy.

The Coronavirus impact in Asia impacted Apple’s supply chain and this can be seen in AAPL price over this year. The chart below indicates the loss of value of Apple’s stock in 2020.

As said before, this strategy reward quality stocks over time. The fluctuation in the short- or mid-term would end at some point and the stock value would rise after the pandemic. If you think the stock value right now is undervalued, then it is the right time to invest in it.

Of course, not only Apple lost value in the middle of this pandemic. If we look into the publicly-traded U.S. stocks owned by Berkshire Hathaway, we can find other companies in the same situation.

Kraft Heinz stock (KHC) value dropped over 27% since January. American Airlines stock (AAL) fell 47% in the same period. America Express stock (AXP) started the year valuing $124.66 and hit almost $68 by the end of March. All of those companies have Buffet’s company as one of their shareholders and might be part of his strategy.
