The P/E Ratio Myth: Why Low Multiples Can Be Deceptive
A low P/E ratio doesn't always mean a stock is cheap — here's how to avoid the trap that even experienced investors fall into.
Key Takeaways
- Low P/E ratios alone are meaningless without growth context
- INTC has traded at a P/E under 15 for years while NVDA has delivered superior returns
- Forward P/E ratios matter more in fast-changing industries
- Critics argue this framework breaks down in cyclical sectors

Most investors see a low P/E ratio and assume they've found a bargain. In reality, low multiples often reflect collapsing growth expectations rather than undervalued cash flow. This distinction is critical for avoiding value traps.
The Value Illusion
INTC currently trades around 10x earnings while NVDA trades near 60x. Based on recent filings, NVDA has compounded revenue at roughly 25% annually compared to INTC's stagnant growth. This explains why INTC's low multiple hasn't translated into superior returns.
A classic example is the tech sector rotation of 2015-2020. IBM traded at a P/E around 10x while MSFT commanded 30x+. Over those five years, MSFT's cloud-driven growth propelled its stock up 300% while IBM languished.
What the Numbers Actually Say
| Ticker | P/E | Forward P/E | 5Y Rev CAGR | ROIC |
|---|---|---|---|---|
| AAPL | ~28 | ~25 | ~8% | ~30% |
| MSFT | ~34 | ~30 | ~14% | ~25% |
| INTC | ~10 | ~15 | ~-2% | ~10% |
| NVDA | ~60 | ~50 | ~25% | ~20% |
| TSLA | ~70 | ~55 | ~35% | ~15% |
The key takeaway: High-growth companies like NVDA and TSLA command premium multiples because their earnings are compounding rapidly. Meanwhile, low-multiple stocks like INTC often face structural challenges.
When Low P/E Ratios Matter
Critics point out that in cyclical sectors like energy and materials, low trailing P/E ratios can signal genuine bargains near cycle troughs. For example, XOM traded at a P/E under 10x during the 2020 oil crash, then tripled as crude prices recovered.
However, timing is everything. XOM spent years trading at single-digit multiples before the rebound. The risk is that cheap can stay cheap for extended periods.
A Better Framework
Instead of focusing solely on P/E ratios, investors should consider:
- Forward P/E ratios: Reflect future earnings potential
- Revenue growth: Indicates business momentum
- Return on invested capital (ROIC): Measures capital efficiency
For example, MSFT's premium multiple is justified by its ~14% revenue growth and ~25% ROIC. Contrast this with INTC's declining sales and 10% ROIC.

No. In mature cash-generative businesses with stable growth, sub-15 P/E ratios can be genuinely cheap. The problem is using P/E in isolation.
