Peter Lynch is renowned for his success as a mutual fund manager at Fidelity Investments and for his straightforward and practical investment philosophy.

Lynch's approach emphasises thorough research, a long-term perspective, and an understanding of the businesses behind the stocks.

Here are three critical pieces of investment advice from the investing legend that can help investors navigate the complexities of the stock market.

Water the flowers, cut the weeds

Imagine reviewing your stock portfolio. Undoubtedly, there are stocks that haven't performed as well as expected when you initially invested in them.

It's intriguing how human psychology works. We often hold onto our losses more tightly than we celebrate gains elsewhere. This is known as 'loss aversion'. Sometimes, we add to the losers, hoping that will lower the poor-performing stock's average purchasing price.

In the contract, Lynch advises you to focus on the winners in your portfolio. In Lynch's metaphor, flowers represent high-quality companies with solid fundamentals, growth potential, and a competitive edge in their industry. These companies are likely to thrive over the long term and generate significant returns for investors.

After all, it is those handful of stocks with oversized gains that will lift your portfolio's overall performance, offsetting losses from some underperforming stocks.

Your portfolio could include Pro Medicus Limited (ASX: PME) or Washington H Soul Pattinson & Company Ltd (ASX: SOL). Make sure the winners keep on winning by adding them whenever appropriate share prices become available.

Invest in what you know

I think this must be one of Peter Lynch's most famous pieces of advice. Lynch recommended investing in companies and industries that you understand. Lynch believes investors can have a significant advantage when investing in familiar industries. By doing this, they can make the most out of their knowledge and expertise gained from day-to-day jobs.

Let's say you work in the medical imaging industry and notice your company is upgrading its systems to improve operational efficiency. If it happens to be products offered by Pro Medicus, you might be lucky enough to be one of the early investors of this fantastic growth stock.

As an insider of the industry, you would be able to understand the company's products, market position, and competitive advantages over its competitors. And all of these can be valuable information when assessing your next investment ideas.

Do your homework

Once you find a candidate for your next investment, it is crucial to continue studying this company in depth. Just having an idea is insufficient. Lynch's investment strategy centres around thorough research.

Lynch believed in digging deep into a company's financial statements, understanding how it makes money and the quality of management. Another famous investor, Warren Buffett, likes to read everything available about a potential candidate company before making an investment decision.

For example, before investing in a company, Lynch recommended studying its annual reports, quarterly earnings releases, and industry publications. By understanding the company's financial health, growth prospects, and potential risks, investors can better evaluate whether it aligns with their investment goals and risk tolerance.

Foolish takeaway

Peter Lynch's timeless advice resonates with both novice and seasoned investors alike.

Investors can build a robust portfolio that stands the test of time by focusing on quality, leveraging their own expertise, and conducting thorough research.
