Investors aiming to assemble a lasting portfolio of good companies at fair prices frequently consider the ideas of famous fund manager Peter Lynch. His method, explained in One Up on Wall Street, centers on finding expanding companies with sound finances and durable business models, yet importantly, ones the market has not valued too highly. This "growth at a reasonable price" (GARP) method steers clear of speculative, expensive stocks for businesses with established earnings, controlled debt, and prices that do not assume many years of future gains. A central measure in this system is the PEG ratio, which evaluates a stock's price-to-earnings (P/E) ratio against its earnings growth rate, a number at or under 1 often marking a fair price.

A recent filter using Lynch's main standards has identified Enphase Energy Inc (NASDAQ:ENPH) as a possible option for this kind of investor. The company, a worldwide frontrunner in microinverter-based solar and battery systems, seems to match many of the method's numerical checks.
The filter uses particular checks to locate companies with a mix of expansion, fair price, and monetary soundness. Enphase Energy's present numbers show a clear match:
A look at Enphase's wider basic analysis report gives background beyond the filter's checks. The company gets an overall basic score of 5 out of 10, showing a varied but notable profile when measured against others in the Semiconductors & Semiconductor Equipment field.

For an investor using a Peter Lynch-style GARP method, Enphase Energy offers a notable example. It shows the signs of a company that has reached marked expansion and high earnings power, but is now priced by the market at a level that does not appear to completely account for this record. The small PEG ratio is the numerical focus of this view. Also, the company works in the long-term expansion area of clean energy technology, supplying products that allow home energy self-reliance, a market with a lasting favorable trend.
However, the Lynch method also needs knowing the business. Possible investors must evaluate if the forecasted reduction in growth is a short-term field challenge or a more lasting change. Also, while the debt amount passes the filter's check, watching the company's financial borrowing will be key. The method’s good result depends on keeping shares during swings, if the central business idea stays valid.
Enphase Energy resulted from a methodical search built on Peter Lynch's ideas. For investors curious about finding other companies that meet these standards for maintainable growth at fair prices, the filter is a practical beginning for more study.
