GARP Investing: How to Find Growth at a Reasonable Price (Like Peter Lynch)
In the 1980s and early 1990s, Peter Lynch ran the Fidelity Magellan Fund to one of the most remarkable records in investment history -- a compounded annual return of roughly 29% over 13 years, turning a $1,000 investment into more than $28,000. Lynch did not do this by buying the cheapest stocks in the market (classic Benjamin Graham value investing) or by chasing the fastest-growing companies regardless of price (momentum growth investing). He did it by identifying businesses growing faster than the market expected, at prices that did not yet fully reflect that growth. He called the approach Growth at a Reasonable Price -- GARP.
GARP remains one of the most practical frameworks available to individual investors because it combines the discipline of valuation with the return potential of growth. This article explains what GARP is, how the PEG ratio works as its primary tool, how GARP differs from adjacent strategies, and how to build a GARP screen in ValueMarkers.

What Is GARP Investing?
GARP occupies a deliberate middle ground on the investing spectrum. At one end sits deep value investing -- buying companies that are statistically cheap relative to assets or earnings, often because the business is in distress or in an unloved sector. At the other end sits pure growth investing -- buying the fastest-growing companies regardless of valuation, on the assumption that future growth will eventually justify any price.
GARP rejects both extremes. The GARP investor refuses to pay 40x earnings for a company growing at 15% (too expensive relative to growth), but also refuses to buy a company trading at 8x earnings that is declining or stagnant (no growth to justify holding). The sweet spot is a company growing earnings at 15-25% per year and trading at a P/E ratio that is at or below that growth rate -- ideally below.
Lynch articulated this with characteristic plainness: "The P/E ratio of any company that is fairly priced will equal its growth rate." A company growing earnings at 15% per year and trading at a P/E of 15 is fairly priced. At a P/E of 10, it is undervalued. At a P/E of 25, it is overvalued -- you are paying for growth that may or may not materialize.
This relationship between P/E and growth rate is formalized in the PEG ratio.
The PEG Ratio: GARP's Primary Tool
PEG = P/E Ratio / EPS Growth Rate
Where EPS Growth Rate is typically the consensus 5-year forward earnings growth estimate or the trailing 5-year EPS CAGR (Lynch preferred the earnings growth rate expected over the next few years).
Interpretation:
- PEG < 1.0: The stock is potentially undervalued relative to its growth -- the market is not fully pricing in the earnings trajectory. This is the GARP sweet spot.
- PEG = 1.0: Fair value by Lynch's rough rule of thumb.
- PEG > 1.5: The stock is pricing in optimistic growth assumptions; risk of disappointment increases.
- PEG > 2.0: Typical of high-flying growth stocks where you are paying a significant premium for expected future growth.
Example: Suppose a company earns $2.00 per share, trades at $30 (P/E = 15), and analysts expect 18% EPS growth annually over 5 years.
PEG = 15 / 18 = 0.83
A PEG of 0.83 says the stock is modestly undervalued relative to its expected growth. If growth materializes as expected, the stock should re-rate toward a PEG of 1.0, implying a fair value P/E of 18x -- a $36 price, or 20% upside from current levels, before accounting for the earnings growth itself.
Important limitations of PEG:
- PEG is only as reliable as the growth estimate in the denominator. Aggressive analyst estimates inflate the PEG denominator and make a stock look cheaper than it is.
- PEG works best for companies growing at 10-30% per year. Very fast growers (40%+) often justify PEGs above 1.5, and slow growers (5-8%) make the ratio less meaningful.
- PEG ignores balance sheet strength, capital intensity, and competitive dynamics. Always use it as a filter, not a final answer.
How GARP Differs From Pure Value and Pure Growth
Understanding where GARP sits in the broader landscape helps clarify what you are optimizing for.
GARP vs. Pure Value: Benjamin Graham-style value investing focuses almost entirely on price relative to current assets, current earnings, or book value. The classic Graham screen (NCAV, low P/B, low P/E) does not require growth -- in fact, it often buys companies with no growth or even declining fundamentals, betting that the price is cheap enough to generate returns purely from mean reversion.
GARP requires growth. A GARP investor would not buy a company trading at 7x earnings if earnings are expected to be flat or declining. The low P/E does not compensate for the absence of earnings power growth. This is why GARP avoids many "value traps" -- stocks that look cheap but stay cheap because the underlying business is deteriorating.
GARP vs. Pure Growth: Pure growth investing (often associated with momentum strategies or the venture-influenced approach popularized in the late 1990s and again in 2020-2021) is willing to pay very high multiples -- 30x, 50x, even 100x earnings -- for companies with exceptional growth trajectories. The premise is that a company growing at 40% per year will grow into even a very high valuation quickly.
The problem is that very high growth rates rarely persist. When a company growing at 40% decelerates to 20%, multiple compression can be violent -- the stock may fall 50% even if earnings are still growing, simply because the market removes the premium it was paying for hypergrowth. GARP investors avoid this risk by requiring that the P/E is already reasonably grounded relative to the actual growth rate.
The 5-Factor GARP Sweet Spot
A practical GARP screen requires not just the PEG ratio but also factors that validate the quality and sustainability of the growth:
1. PEG Ratio: 0.5 to 1.0 This is the primary filter. PEG below 0.5 may indicate cheap-for-a-reason (declining business, sector headwinds, one-time earnings spike). PEG between 0.5 and 1.0 is the genuine sweet spot -- growth that the market has modestly underpriced. Avoid PEG above 1.5 for GARP purposes.
2. Return on Equity > 15% High ROE is evidence that the company has a genuine competitive advantage -- the ability to earn excess returns on capital deployed. GARP avoids companies growing via low-return expansion (e.g., acquiring low-ROE assets). Growing earnings through high-ROE reinvestment is the compounding engine that makes GARP sustainable.
3. Five-Year EPS CAGR > 15% The growth rate used in the PEG denominator should be verified against historical performance, not just forward estimates. A company that has grown EPS at 18% per year for the last five years has demonstrated the ability to deliver that growth, giving you more confidence in the forward estimate. Companies with strong historical EPS CAGR have more credible paths to continued growth.
4. Debt-to-Equity < 1.0x Highly leveraged growth companies carry binary risk: their growth strategy works and they look brilliant, or leverage amplifies a downturn and they face financial distress. GARP investors prefer growth funded by organic cash generation or modest, well-deployed leverage. D/E below 1.0x keeps the downside manageable.
5. Positive Free Cash Flow Net income can be inflated by accounting choices. Free cash flow (operating cash flow minus capex) is harder to manipulate. A GARP company should be converting its earnings growth into actual cash, not just reported profits. Positive and growing FCF validates that the earnings trajectory is real and sustainable.
Sector Focus for GARP
Not all sectors are equally fertile for GARP because some industries have structural constraints on sustainable growth rates or valuation norms that distort PEG calculations.
Consumer discretionary has historically been a strong GARP sector. Companies in branded retail, restaurants, and consumer services can grow through store expansion, pricing power, and international rollouts while maintaining unit economics that produce high ROE and strong FCF.
Technology is the most discussed GARP sector, but requires care. Software-as-a-service businesses with high gross margins, recurring revenue, and strong retention metrics can justify PEGs above pure value thresholds -- but many technology companies reinvest so heavily that near-term FCF is artificially depressed. Apply PEG to companies with established profitability, not pre-profit hypergrowth.
Healthcare -- particularly medical devices, diagnostics, and specialty pharmaceuticals -- often produces GARP candidates because the sector's defensive earnings profile leads to market undervaluation during growth periods. Patent pipelines, regulatory approvals, and aging demographics create multi-year growth visibility.
Avoid highly cyclical sectors (commodity producers, shipping, basic materials) for GARP because the "growth rate" oscillates with commodity cycles. The PEG ratio loses meaning when earnings double and halve with the price of iron ore.
How GARP Avoids Value Traps
One of GARP's most practical advantages is its built-in value trap filter. A value trap is a company that appears cheap on traditional metrics (low P/E, low P/B) but whose earnings are declining, making the cheapness an illusion -- the denominator is shrinking.
Consider a retailer trading at 8x trailing earnings. That looks cheap. But if earnings are declining 10% per year due to e-commerce disruption, the forward P/E is already above 9x, and in two years it will be above 12x -- and the stock will likely be even lower. The GARP investor's requirement for positive EPS growth (manifested in the PEG denominator) automatically screens out this scenario. If EPS growth is negative, the PEG ratio is negative or undefined -- a clear signal to avoid.
GARP does not guarantee against losses, and growth estimates can be wrong. But the combination of reasonable valuation and demonstrated growth creates a much wider margin of safety than either criterion alone.
Historically Famous GARP Stocks
Lynch himself identified some of his best investments through GARP principles: Dunkin' Donuts, La Quinta Motor Inns, and Stop & Shop in the 1980s were growing faster than the market appreciated and trading at P/Es that underpriced that growth.
In more recent decades, companies like Visa, Mastercard, and UnitedHealth Group spent years as GARP stocks -- growing earnings at 15-20% per year while trading at PEGs below 1.0, before the market fully recognized their compounding power and re-rated them to premium valuations. By definition, the best GARP stocks eventually become expensive enough that they are no longer GARP candidates -- they graduate into fairly or fully valued status, at which point GARP investors trim or exit.
This is an important behavioral discipline embedded in GARP: it forces you to sell when valuation catches up to growth. You are not holding a stock at a PEG of 3.0 because you believe in the company's long-term vision. You sell when the market has fully priced the growth, and look for the next misvalued grower.
How to Screen for GARP in ValueMarkers
ValueMarkers allows you to combine fundamental filters into a custom screening workflow:
Step 1: Filter for PEG ratio between 0.5 and 1.0 using the 5-year EPS growth estimate as the denominator.
Step 2: Add ROE > 15% and positive FCF to verify quality and earnings reality.
Step 3: Set D/E < 1.0x to remove over-leveraged names where balance sheet risk could disrupt the growth trajectory.
Step 4: Filter for 5-year historical EPS CAGR > 15% to validate that forward estimates are grounded in demonstrated performance.
Step 5: Sort results by 5-year EPS CAGR descending to identify the fastest growers that still meet the valuation discipline.
Step 6: Cross-check individual names against the ValueMarkers intrinsic value calculator to verify that the DCF-implied value is above the current market price -- adding a second layer of valuation confirmation beyond the PEG.
Run this screen monthly rather than daily. GARP opportunities arise most often during broad market selloffs (when growth stocks are indiscriminately repriced lower) and during sector-specific corrections (when good companies fall alongside bad ones). Lynch's famous "buy what you know" advice pairs naturally with GARP: when you understand an industry deeply, you recognize inflection points in growth trajectories before they appear in analyst consensus estimates, and you can buy at a PEG below 1.0 before the upgrade cycle begins.
