For me, ROE is the key “engine” of compounding. A company with consistently high ROE and limited leverage shows strong underlying economics. Still, valuation matters — buying even the best business at the wrong PE can lead to weak returns. I see ROE as measuring business quality, while PE tells me how much I’m paying.

That said, I often give more weight to ROIC and free cash flow. ROIC reflects how efficiently a company uses all capital, not just equity, while free cash flow is the real money available to fund growth, dividends, or buybacks. Together, they provide a clearer picture of whether compounding is sustainable.

If I had to choose only one metric for a 10-year investment, I’d pick ROIC. It balances profitability with capital efficiency and avoids distortions from leverage. PE moves with sentiment, and ROE can be flattered, but high ROIC paired with steady cash flow growth gives me the most confidence in long-term compounding.

Long-Term Investing: Look at ROE or PE?
Many investors have heard the idea that “long-term compounding ≈ ROE.” This concept was first put forward by Charlie Munger, known as the Munger Rule. In his 1981 shareholder letter, Warren Buffett also pointed out that if PE remains unchanged, a company with 14% ROE will generate a long-term investment compound return of 14% as well. When picking stocks for the long run, do you focus more on ROE or PE? Why? Do you think ROIC and FCF are more important than ROE in compounding? If you could only choose one metric for a 10-year investment decision, which one would it be?
