📖Peter Lynch
Growth at Reasonable Price
Use the PEG ratio to find fairly valued growth stocks.
The P/E ratio of any company that's fairly priced will equal its growth rate. If the P/E is lower than the growth rate, you may have found yourself a bargain.
🏠 Everyday Analogy

❓ Why It Matters
Ignoring valuation turns even good companies into poor investments. Overpaying compresses future returns and leaves little margin when assumptions are wrong.
🎯 How to Practice
Estimate intrinsic value with conservative assumptions, set clear buy ranges, and act only when price offers a meaningful discount with acceptable downside.
⚠️ Common Pitfalls
Confusing a low price with true cheapness
Using one metric without business context
Overly optimistic assumptions that erase margin of safety
