When I try to find cheap shares to buy, it is not a random process. Instead I follow an approach including some lessons from famed investor Warren Buffett. Here are three ways I have been applying the Warren Buffett method in my recent investing experiences.

Circle of competence

Like Warren Buffett, I focus on my own circle of competence when investing. That means I try to stick to industries I understand and businesses I think I have the necessary skills to assess.

A circle of competence is not fixed. If I want to expand it, I can learn more about a certain business area. So, for example, before buying Boohoo I spent time getting a greater understanding of the online fashion retail sector. But if I do not feel that I understand an area, I will follow Buffett’s approach and stay away from it. Sometimes shares may look cheap to me but are value traps I cannot spot if they are because I do not understand their businesses. By sticking to what I know, I feel more confident I can identify shares that are actually cheap.

Cheapness and value

A cheap share price on its own does not mean that an investment is good value. Like Buffett, I look at the future prospects of a business not just its current share price.

To generate strong profits over the long term, a company typically needs some sort of competitive advantage. That can help set it apart in its market and allows it to charge a premium price. For example, Buffett owns shares in Coca-Cola. Its unique formula is something competitors cannot copy directly. That gives it pricing power and so it can earn a good profit.

I also look for similar company characteristics when hunting for cheap shares to add to my portfolio. So, for example, I think Intuitive Surgical has a strong competitive advantage. Its proprietary robotic surgery machines can improve the efficiency of medical care providers. The more time a user spends learning about one, the higher the switching cost to learn how to use a competitor’s machine. But while I like the business model, I do not think the Intuitive Surgical share price currently offers me good value. To make an investment, as Buffett says, I am looking for great companies selling at good prices.

The Warren Buffett method assumes little

Some investors make a lot of assumptions when buying shares. Those can be assumptions about the direction of the economy, future consumer trends or many other issues.

When Buffett explains his reasons for buying specific shares, I notice that he often makes few assumptions. He relies on facts, as for example reported in a company’s accounts, and then assumes as little as possible.

For example, by investing in railways, Buffett assumes there will be high demand in future for freight to keep travelling by train. That is an assumption. But I think it is a smaller one than expecting a paradigm shift in transportation modes, the sort of assumption that might underpin an investment in some transport shares.

Fewer assumptions and more facts help make it easier for me to assess potential investments objectively. Like Warren Buffett, I think that approach can help me spot shares I would want to buy and hold for years.

Should you invest, the value of your investment may rise or fall and your capital is at risk. Before investing, your individual circumstances should be assessed. Consider taking independent financial advice.
