For long-term investors aiming to build wealth through a disciplined, fundamental method, few strategies are as respected as Peter Lynch's methodology. The famous manager of Fidelity's Magellan Fund supported investing in what you understand, concentrating on companies with durable growth, sound financial health, and fair valuations. His method, often called Growth at a Reasonable Price (GARP), does not choose speculative high-flyers, instead preferring businesses that can provide steady, long-term returns. A filter using Lynch's main ideas recently found Otter Tail Corp (NASDAQ:OTTR) as a possible candidate for more examination.

The filter used a number of quantitative measures taken from Lynch's thinking. Here is how Otter Tail Corp compares against these important tests:
While the filter gives a good first step, Lynch always noted the need for more careful study. A look at Otter Tail's wider fundamental analysis report shows a company with clear positives and some points to note.
The company receives a high total fundamental score of 7 out of 10, led by very high scores in Profitability (9/10) and good marks in Financial Health (7/10). Its margins and returns on capital are near the best in the Electric Utilities industry. However, the report mentions a lower score in Growth (3/10), showing a recent deceleration and low future earnings projections, a detail that needs thoughtful assessment for a GARP investor.
For an investor following Peter Lynch's thinking, Otter Tail Corp offers an interesting example. It is not a trendy tech stock but a varied utility and manufacturing holding company, exactly the sort of "ordinary" business Lynch liked for its clarity. The company has produced the type of steady, better-than-average earnings growth Lynch wanted, and it now trades at a price, as shown by the very low PEG ratio, that seems not to account for this historical record.
The good profitability numbers and careful balance sheet match Lynch's emphasis on financial strength, which is important for surviving economic changes. The recent deceleration in growth and earnings outlooks, while a note of caution, is a recall of Lynch's central belief: near-term forecasts are unreliable, but a good company bought at a logical price can benefit those who wait over many years. The main question for a possible investor is if the company's core utilities and manufacturing units can find again a maintainable, mid-single-digit growth course over the long term.
Otter Tail Corp came from a structured search for companies fitting a disciplined investment model. For investors looking to find other possible candidates that meet similar tests for maintainable growth and fair valuation, the Peter Lynch Strategy screen is frequently refreshed and can be a useful tool for more study.
