Growth-adjusted valuations that reveal what Lynch would call cheap.
View Lynch's valuationsNo. In mature, stable businesses with predictable cash flows, a low P/E can signal genuine undervaluation. The key is assessing the sustainability of earnings.
Value investors love low P/E stocks, but blindly chasing low multiples has been a costly mistake for decades. The reality? Stocks can be cheap for a reason.
INTC trades at around 10x trailing earnings, while NVDA commands a P/E of ~60x. Yet over the last decade, NVDA has compounded revenue at ~25% annually, while INTC has stagnated. The result? NVDA shareholders have seen ~1,200% returns since 2016, while INTC investors are down ~15%.
This isn’t just about tech. WMT trades at ~25x earnings — higher than INTC — but has delivered steady mid-single-digit revenue growth and ~150% total returns over the same period.
| Ticker | P/E | Forward P/E | 5Y Rev CAGR | FCF Yield |
|---|---|---|---|---|
| AAPL | ~28 | ~25 | ~8% | ~4.5% |
| MSFT | ~34 | ~30 | ~14% | ~3.8% |
| INTC | ~10 | ~15 | ~-2% | ~1.2% |
| AMD | ~45 | ~28 | ~25% | ~2.1% |
| WMT | ~25 | ~23 | ~4% | ~3.3% |
The table reveals a clear pattern: higher-growth companies like AMD and MSFT tend to command premium multiples, while low-P/E stocks like INTC often have deteriorating fundamentals.
Low P/E stocks can be particularly dangerous in declining industries. Consider GE in 2016: it traded at ~15x earnings, but revenue was shrinking at ~5% annually. Investors who bought the "cheap" multiple lost ~60% over the next 5 years as earnings collapsed.
Critics of this framework argue that low P/E works better in stable, cash-generative industries like consumer staples. However, even in these sectors, high-quality names like KO and PG rarely trade at single-digit multiples.
There are cases where low P/E stocks outperform — particularly in deep cyclicals near the bottom of their cycle. F traded at ~7x earnings in 2020 before rallying ~300% as auto demand recovered. However, timing these cycles is notoriously difficult.
