3 Large-Cap Stocks That Concern Us

Large-cap stocks usually command their industries because they have the scale to drive market trends. The flip side though is that their sheer size can limit growth as expanding further becomes an increasingly challenging task.

This dynamic can trouble even the most skilled investors, but luckily for you, we started StockStory to help you navigate these trade-offs and uncover exceptional companies that break the mold. That said, here are three large-cap stocks whose momentum may slow and a few alternatives you should consider instead.

Paychex (PAYX)

Market Cap: $40.09 billion

Once known as the go-to service for small business payroll needs, Paychex (NASDAQ:PAYX) provides payroll processing, HR services, employee benefits administration, and insurance solutions to small and medium-sized businesses.

Why Does PAYX Worry Us?

  1. Annual revenue growth of 9.4% over the last five years was well below our standards for the software sector

  2. Estimated sales growth of 5.3% for the next 12 months implies demand will slow from its two-year trend

  3. Operating profits and efficiency rose over the last year as it benefited from some fixed cost leverage

Paychex is trading at $112.31 per share, or 5.7x forward price-to-sales. To fully understand why you should be careful with PAYX, check out our full research report (it’s free).

Republic Services (RSG)

Market Cap: $71.34 billion

Processing several million tons of recyclables annually, Republic (NYSE:RSG) provides waste management services for residences, companies, and municipalities.

Why Are We Hesitant About RSG?

  1. Annual sales growth of 4.2% over the last two years lagged behind its industrials peers as its large revenue base made it difficult to generate incremental demand

  2. Flat unit sales over the past two years imply it may need to invest in improvements to get back on track

  3. Estimated sales growth of 5.2% for the next 12 months is soft and implies weaker demand

Republic Services’s stock price of $232.07 implies a valuation ratio of 30x forward P/E. Read our free research report to see why you should think twice about including RSG in your portfolio, it’s free.

Rockwell Automation (ROK)

Market Cap: $47.5 billion

One of the first companies to address industrial automation, Rockwell Automation (NYSE:ROK) sells products that help customers extract more efficiency from their machinery.

Why Does ROK Give Us Pause?

  1. Absence of organic revenue growth over the past two years suggests it may have to lean into acquisitions to drive its expansion

  2. Anticipated sales growth of 5.2% for the next year implies demand will be shaky

  3. Waning returns on capital imply its previous profit engines are losing steam
