For long-term investors looking for a disciplined way to pick stocks, few strategies are as respected as Peter Lynch’s method. As the famous manager of Fidelity’s Magellan Fund, Lynch supported a "growth at a reasonable price" (GARP) idea, concentrating on companies with good, lasting earnings growth, sound financial condition, and prices that do not overvalue that growth. His system, explained in One Up on Wall Street, stresses fundamental study and a buy-and-hold perspective, guiding investors toward businesses that are both successful and carefully run. A filter using his main rules recently found Mueller Water Products Inc-A (NYSE:MWA) as a possible choice for more examination.

A Match for the Lynch Method
Mueller Water Products, a maker of needed infrastructure for water movement, delivery, and measurement, works in what Lynch might name a "simple" but very necessary field. The company’s profile, providing valves, hydrants, leak detection, and metering systems, fits with the thought of putting money in clear businesses with lasting need. Following the Lynch filter settings, MWA satisfies several important number-based tests that try to find good growth at a sensible price.
- Lasting Earnings Growth: Lynch preferred companies increasing earnings per share (EPS) between 15% and 30% each year, a span seen as lasting. MWA’s five-year EPS growth rate of 20.76% sits directly inside this goal area, showing a record of solid, but not excessive, increase.
- Sensible Price via PEG: A key part of the Lynch method is the Price/Earnings to Growth (PEG) ratio, which changes the standard P/E ratio for a company’s growth rate. Lynch wanted a PEG of 1 or below, meaning the market is not overpricing the available growth. MWA’s PEG ratio, using past five-year growth, is 0.98, meeting this test for sensible price.
- High Profitability (ROE): Return on Equity (ROE) checks how well a company creates profits from shareholder equity. Lynch searched for an ROE above 15%. MWA’s ROE of 19.53% is well above this line, indicating good management and a successful business plan.
- Sound Financial Condition: Lynch stressed financial sturdiness to handle economic changes. Two main measures from the filter confirm MWA’s condition:
- Debt/Equity Ratio: At 0.46, MWA’s debt amount is low, showing it is financed more by equity than debt and has a workable financial load.
- Current Ratio: A ratio of 3.54 shows the company has more than enough short-term assets to pay its near-term debts, giving a good cash safety net.
Fundamental Study Summary
A wider fundamental analysis of Mueller Water Products supports the image shown by the Lynch filter. The company gets a good total fundamental score of 7 out of 10, with specific high points in profitability and financial condition.
- Profitability High Point: The company scores a 9 out of 10 in profitability. Margins are solid and getting better, with an operating margin of 19.13% that beats almost 89% of similar companies in the machinery field. The high and steady returns on assets, equity, and invested capital further highlight its effective use of money.
- Very Good Financial Condition: With a health score of 8 out of 10, MWA shows a very strong balance sheet. The high current and quick ratios confirm better-than-average cash availability, while a low debt-to-equity ratio and a good Altman-Z score point to very little chance of failure.
- Growth and Price Setting: The growth score is middle at 5, showing a strong past growth path that is thought to slow in the close future based on expert forecasts. The price score is also a 5. While the P/E ratio seems high by itself, it costs less than most field peers and the wider S&P 500. The price is backed by the company’s excellent profitability.
Points for Investors
While the Lynch filter shows positive traits, investors should think about the whole situation. The company’s dividend, while steady with a 10-year payment history, gives a small return. Also, expert forecasts point to a decrease in sales and EPS growth in the next few years. This possible slowdown is a main point for investors to weigh when judging how long the company’s past results will continue and its future "growth at a reasonable price" attraction.
