Growth at a Reasonable Price (GARP): The Best of Both Worlds

Growth investors chase fast-growing companies. Value investors hunt for bargains. GARP investors refuse to choose—they want both. On Portfolio Genius, the Growth at a Reasonable Price strategy template tells the AI to find companies with above-average earnings growth that aren't trading at sky-high valuations.

This is the fourth post in our Strategy Spotlight series. We've already covered risk-based strategies, Dividend Growth, and Value Investing (Buffett-Style). Today we tackle the approach made famous by Peter Lynch, one of the greatest mutual fund managers in history.

What Is GARP?

Growth at a Reasonable Price is an investment philosophy that combines growth investing with value discipline. Instead of paying any price for fast growth (pure growth investing) or buying cheap stocks regardless of growth prospects (deep value), GARP targets the sweet spot: companies growing faster than average but still trading at a reasonable valuation.

Peter Lynch popularized GARP during his legendary run at the Magellan Fund, where he averaged 29% annual returns from 1977 to 1990. His approach was simple: find companies growing earnings at 15–30% per year whose stock price doesn't already reflect that growth. The tool he championed for this? The PEG ratio.

Key Concepts the AI Targets

How AI Manages This Strategy on Portfolio Genius

When you select the Growth at a Reasonable Price template, the AI receives a specific mandate: find companies with above-average earnings growth that trade at reasonable valuations. Here's what that looks like in practice.

Who Is GARP For?

GARP sits in the middle ground between aggressive growth and conservative value. It's well-suited for investors who want more upside than a pure value portfolio but less risk than betting on unprofitable high-growth stocks.

• Balanced investors who want growth exposure without stomach-churning volatility. GARP's valuation discipline provides a natural floor under stock prices—you're less likely to overpay, which limits drawdowns when sentiment shifts.
• Former growth investors burned by momentum crashes. If you've held a stock that dropped 60% after missing earnings by a penny, GARP's insistence on reasonable valuations helps prevent that scenario. The margin of safety is smaller than deep value, but it's there.
• Medium-term investors with a 3–7 year time horizon. GARP works best when you hold long enough for earnings growth to compound but stay active enough to rotate out of positions when growth decelerates or valuations stretch.
• Fundamental stock pickers who enjoy analyzing earnings reports and growth trajectories. GARP rewards investors who understand the difference between a company growing revenue at 20% with expanding margins and one growing at 20% by acquiring competitors with debt.

GARP vs. Pure Growth vs. Deep Value

Understanding where GARP sits on the spectrum helps you decide if it's the right fit. Each approach makes different trade-offs between growth potential and downside protection:

On Portfolio Genius, you can run all three strategies in separate portfolios to see which approach your preferred AI model executes best. The Strategy Zoo leaderboard makes it easy to compare them side by side.

The AI's GARP Checklist

Here's a simplified view of the criteria the AI applies when screening for GARP investments. Strong candidates pass most of these tests:

The AI balances these criteria based on the broader market environment. In expensive markets with few bargains, it may accept slightly higher PEG ratios for exceptionally strong growth profiles. In cheaper markets, it tightens valuation requirements and becomes more selective.

You can watch in real time how different AI models interpret the same GARP mandate—which growth stocks they consider “reasonable,” how strictly they apply the PEG filter, and who delivers the best risk-adjusted returns.
