While strong cash flow is a key indicator of stability, it doesn’t always translate to superior returns. Some cash-heavy businesses struggle with inefficient spending, slowing demand, or weak competitive positioning.

Luckily for you, we built StockStory to help you separate the good from the bad. That said, here is one cash-producing company that excels at turning cash into shareholder value and two best left off your watchlist.

Two Stocks to Sell:

Rapid7 (RPD)

Trailing 12-Month Free Cash Flow Margin: 15%

With its name inspired by the need for quick responses to cyber threats, Rapid7 (NASDAQ: RPD) provides cybersecurity software and services that help organizations detect vulnerabilities, monitor threats, and respond to security incidents.

Why Do We Think RPD Will Underperform?

1. Offerings struggled to generate meaningful interest as its average billings growth of 1.3% over the last year did not impress
2. Competitive market means the company must spend more on sales and marketing to stand out even if the return on investment is low
3. Day-to-day expenses have swelled relative to revenue over the last year as its operating margin fell by 2.8 percentage points

Rapid7’s stock price of $6.82 implies a valuation ratio of 0.5x forward price-to-sales. To fully understand why you should be careful with RPD, check out our full research report (it’s free).

Crane NXT (CXT)

Trailing 12-Month Free Cash Flow Margin: 13.4%

Born from a corporate transformation completed in 2023, Crane NXT (NYSE: CXT) provides specialized technology solutions for payment processing, banknote security, and authentication systems for financial institutions and businesses.

Why Are We Wary of CXT?

1. Annual revenue growth of 3.3% over the last three years was below our standards for the business services sector
2. Earnings per share fell by 1.3% annually over the last two years while its revenue grew, showing its incremental sales were much less profitable
3. 7.9 percentage point decline in its free cash flow margin over the last four years reflects the company’s increased investments to defend its market position

Crane NXT is trading at $44.20 per share, or 10.6x forward P/E. Dive into our free research report to see why there are better opportunities than CXT.

One Stock to Watch:

Interface (TILE)

Pioneering carbon-neutral flooring since its founding in 1973, Interface (NASDAQ: TILE) is a global manufacturer of modular carpet tiles, luxury vinyl tile (LVT), and rubber flooring that specializes in carbon-neutral and sustainable flooring solutions.

Why Are We Positive On TILE?

1. Performance over the past two years shows its incremental sales were extremely profitable, as its annual earnings per share growth of 38.9% outpaced its revenue gains
2. Free cash flow margin increased by 3.9 percentage points over the last five years, giving the company more capital to invest or return to shareholders
