Should You Invest in the Companies You Use Every Day?

It is easy to see the appeal of investing in companies whose products feature in your daily life.

You understand what they sell. You may have first-hand experience of the customer service, pricing and product quality. Compared with an unfamiliar industrial group or specialist software provider, the business can feel easier to assess.

That familiarity may be a useful starting point. It should not be the final reason for investing.

A good product is not automatically a good business, and a good business is not automatically a good investment at any price. The challenge is to separate what you know as a customer from what you need to know as a shareholder.

Familiarity can help generate ideas

Customers sometimes notice changes before they appear clearly in financial statements. They might see fuller shops, rising prices, improving service or a product becoming part of everyday behaviour.

This kind of observation can generate useful questions:

• Are customers returning regularly?
• Does the product appear difficult to replace?
• Can the company increase prices without damaging demand?
• Is the business expanding its relationship with existing customers?
• Does the brand appear to have earned trust?

These observations may help an investor decide which companies deserve further research. They do not prove that revenue, profit or cash flow will grow.

Your personal experience is also a tiny sample. A service that suits you may be unpopular elsewhere. Your local branch may perform differently from the wider estate. You may also belong to a particularly valuable customer group that does not represent the average buyer.

Treat product familiarity as a lead, not evidence strong enough to support an investment decision by itself.

The customer and shareholder see different things

Customers tend to focus on the visible product. Shareholders must assess the entire economic structure behind it.

A popular service might require heavy spending to maintain. A busy retailer might operate on thin margins. A well-known brand could carry significant debt or face strong competition. None of those issues is obvious from simply using the product.

An investor therefore needs to look beyond customer satisfaction and ask:

1. How does the company make money? Identify the main sources of revenue and the costs required to produce them.
2. Does growth create cash? Sales growth is less attractive if it depends on permanently high spending or generous incentives.
3. What is the balance-sheet risk? Debt can reduce a company’s room to respond when trading conditions deteriorate.
4. How durable is demand? Consider whether customers stay because of genuine advantages, convenience or merely temporary fashion.
5. What could weaken the economics? Competition, regulation, changing technology and rising input costs can all alter an investment case.

The risk may also come from outside the normal customer experience. The effect of policy or legal change, for example, can become central to the valuation of an asset. This is illustrated by the discussion of legislative uncertainty and portfolio valuation.

Valuation still matters

Even an excellent company can produce a disappointing investment if its shares are bought at a price that assumes near-perfect execution.

The share price reflects expectations about the future. When expectations are already high, the company may need to deliver substantial growth merely to justify its valuation. A small setback can then have a disproportionate effect on investor sentiment.

Valuation-led analysis asks what assumptions are embedded in the price. Rather than stopping at “this is a strong brand”, an investor might ask:

• What rate of growth appears necessary to justify the valuation?
• How much of that growth depends on entering new markets?
• Are margins expected to improve, and why?
• What happens if growth is slower than hoped?
• Does the potential return provide enough compensation for the risks?

No valuation method provides certainty. Its purpose is to impose discipline and expose the assumptions required for an investment to work.

Beware of the familiarity bias

People often feel safer with names they recognise. In investing, that feeling can be misleading.

Familiarity may be mistaken for predictability. Investors can become more willing to overlook an expensive valuation, weak balance sheet or changing competitive position because they interact with the product every day.

There is also a risk of confirmation bias. Once someone owns shares, an enjoyable customer experience may be interpreted as support for the investment case. Negative information may receive less attention.

A simple safeguard is to write down the investment case before buying. Include the reasons the business might succeed, the assumptions being made and the developments that would challenge the original view.

It can also help to ask the reverse question: if you had never used this company’s products, would its financial characteristics and valuation still interest you?

Your spending habits are not a diversified portfolio

A portfolio built around personal consumption can become concentrated without the investor noticing.

Many everyday products come from similar types of business. A selection based on apps, subscriptions, retailers and consumer devices may leave the portfolio heavily exposed to consumer spending or technology, even if it contains several different company names.

Geography can create another concentration. Investors may favour businesses prominent in their home market while overlooking opportunities elsewhere. Employment can add further overlap. Someone working in technology who also owns mostly technology shares has both their income and investments tied to the same sector.

Diversification is not simply owning more companies. It means spreading exposure across different business models, sectors, regions and economic risks.

Position size matters as well. A promising idea does not need to dominate the portfolio. Limiting the size of individual holdings can reduce the damage caused by an error, unexpected event or permanent loss of capital.

A more disciplined way to use familiarity

Investors do not have to choose between familiar-brand investing and valuation-led investing. The two approaches can be combined.

A practical process might look like this:

1. Notice the product or service. Use personal experience to generate an idea.
2. Define the apparent advantage. Explain why customers choose it and whether that advantage could endure.
3. Study the economics. Review profitability, cash generation, capital requirements and financial resilience.
4. Identify the main risks. Include competition, disruption, regulation and dependence on key products or markets.
5. Assess the valuation. Determine what future performance appears to be reflected in the share price.
6. Check portfolio overlap. Consider whether the holding increases an existing sector, geographic or economic concentration.
7. Set review conditions. Decide which developments would strengthen or weaken the investment case.

This process turns familiarity into a research advantage while retaining the discipline needed for portfolio construction.

Let familiarity open the door, not make the decision

Knowing a company’s products can make a business easier to understand. It may also help an investor ask sharper questions about demand, customer loyalty and competitive positioning.

But the investment outcome depends on more than product quality. Financial strength, valuation, expectations and portfolio concentration all matter.

The most useful approach is to treat everyday experience as the beginning of analysis. The decision itself should rest on a broader assessment of the business, the price being paid and the risk it adds to the portfolio.
