Abstract generation in progress

For decades, investors relied on the price-to-book (P/B) ratio to spot undervalued stocks. That strategy made sense when tangible assets dominated corporate balance sheets. But the business world has transformed. Over the last 40 years, intangible assets—software, patents, brand equity—now represent more than 80% of the S&P 500’s asset base, making traditional metrics increasingly unreliable.

Warren Buffett identified the real winner: free cash flow. This isn’t just theory backed by opinion. Between 2002 and mid-2024, portfolios built on free cash flow yield crushed their P/B counterparts. A price-to-book strategy returned 519%, while free-cash-flow-focused portfolios delivered over 1100%—more than double the gains.

The ETF Playbook for Cash Flow Hunters

Three flagship funds exemplify this shift in investor strategy. The Pacer U.S. Cash Cows 100 ETF (COWZ) selects 100 companies from the Russell 1000 with robust cash generation and solid balance sheets. Meanwhile, VictoryShares Free Cash Flow ETF (VFLO) targets profitable large-cap enterprises combining high free cash flow yields with growth potential. The Invesco Nasdaq Free Cash Flow Achievers ETF (QOWZ) takes a different angle—it emphasizes consistent, stable free cash flow expansion over time.

What’s notable is portfolio overlap. Holdings like Exxon Mobil (XOM), Qualcomm (QCOM), and NVIDIA (NVDA) appear across multiple funds, suggesting institutional conviction around these cash generators.

Why This Matters Now

The rise of cash flow management software tools has made it easier for corporations to optimize their operations and accelerate free cash generation. As more companies sharpen their financial discipline, investors who focus on free cash flow metrics gain a clearer view of which businesses truly deserve premium valuations. The data speaks clearly—companies with strong, sustainable cash flows outperform everything else over the long haul.
