1 Profitable Stock for Long-Term Investors and 2 Facing Challenges

PINS Cover Image

While profitability is essential, it doesn’t guarantee long-term success. Some companies that rest on their margins will lose ground as competition intensifies - as Jeff Bezos said, "Your margin is my opportunity".

A business making money today isn’t necessarily a winner, which is why we analyze companies across multiple dimensions at StockStory. That said, here is one profitable company that leverages its financial strength to beat the competition and two that may struggle to keep up.

Two Stocks to Sell:

Comcast (CMCSA)

Trailing 12-Month GAAP Operating Margin: 18.7%

Formerly known as American Cable Systems, Comcast (NASDAQ: CMCSA) is a multinational telecommunications company offering a wide range of services.

Why Should You Dump CMCSA?

  1. Sluggish trends in its domestic broadband customers suggest customers aren’t adopting its solutions as quickly as the company hoped
  2. Sales are projected to remain flat over the next 12 months as demand decelerates from its two-year trend
  3. Below-average returns on capital indicate management struggled to find compelling investment opportunities

Comcast is trading at $33.75 per share, or 7.7x forward P/E. Dive into our free research report to see why there are better opportunities than CMCSA.

STERIS (STE)

Trailing 12-Month GAAP Operating Margin: 15.9%

With a mission critical role in preventing healthcare-associated infections, STERIS (NYSE: STE) provides infection prevention products, sterilization services, and medical equipment that help healthcare facilities and life science companies maintain sterile environments.

Why Are We Hesitant About STE?

  1. ROIC of 5% reflects management’s challenges in identifying attractive investment opportunities

STERIS’s stock price of $230.46 implies a valuation ratio of 23.1x forward P/E. If you’re considering STE for your portfolio, see our FREE research report to learn more.

One Stock to Watch:

Pinterest (PINS)

Trailing 12-Month GAAP Operating Margin: 5.3%

Created with the idea of virtually replacing paper catalogues, Pinterest (NYSE: PINS) is an online image and social discovery platform.

Why Could PINS Be a Winner?

  1. Monthly Active Users are rising, meaning the company can increase revenue without incurring additional customer acquisition costs if it can cross-sell additional products and features
  2. Disciplined cost controls and effective management resulted in a strong two-year EBITDA margin of 27%
  3. PINS is a free cash flow machine with the flexibility to invest in growth initiatives or return capital to shareholders

At $38.05 per share, Pinterest trades at 20.9x forward EV/EBITDA. Is now the right time to buy? Find out in our full research report, it’s free.
