1 Profitable Stock with Promising Prospects and 2 to Avoid

EHTH Cover Image

Not all profitable companies are built to last - some rely on outdated models or unsustainable advantages. Just because a business is in the green today doesn’t mean it will thrive tomorrow.

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 generates reliable profits without sacrificing growth and two best left off your watchlist.

Two Stocks to Sell:

eHealth (EHTH)

Trailing 12-Month GAAP Operating Margin: 8.4%

Aiming to address a high-stakes and often confusing decision, eHealth (NASDAQ: EHTH) guides consumers through health insurance enrollment and related topics.

Why Do We Think Twice About EHTH?

  1. Value proposition isn’t resonating strongly as its estimated membership averaged 1.8% drops over the last two years
  2. Forecasted revenue decline of 3.4% for the upcoming 12 months implies demand will fall off a cliff
  3. Unfavorable liquidity position could lead to additional equity financing that dilutes shareholders

eHealth’s stock price of $4.16 implies a valuation ratio of 2.7x forward EV/EBITDA. Check out our free in-depth research report to learn more about why EHTH doesn’t pass our bar.

Kraft Heinz (KHC)

Trailing 12-Month GAAP Operating Margin: 6.2%

The result of a 2015 mega-merger between Kraft and Heinz, Kraft Heinz (NASDAQ: KHC) is a packaged foods giant whose products span coffee to cheese to packaged meat.

Why Do We Steer Clear of KHC?

  1. Falling unit sales over the past two years indicate demand is soft and that the company may need to revise its product strategy
  2. Projected sales decline of 1.6% for the next 12 months points to an even tougher demand environment ahead
  3. Costs have risen faster than its revenue over the last year, causing its operating margin to decline by 11.2 percentage points

At $26.62 per share, Kraft Heinz trades at 9.9x forward P/E. If you’re considering KHC for your portfolio, see our FREE research report to learn more.

One Stock to Watch:

United Parks & Resorts (PRKS)

Trailing 12-Month GAAP Operating Margin: 26.7%

Parent company of SeaWorld and home of the world-famous Shamu, United Parks & Resorts (NYSE: PRKS) is a theme park chain featuring marine life, live entertainment, roller coasters, and waterparks.

Why Are We Fans of PRKS?

  1. Highly efficient business model is illustrated by its impressive 26.9% operating margin
  2. Performance over the past five years was turbocharged by share buybacks, which enabled its earnings per share to grow faster than its revenue
  3. Rising returns on capital show management is finding more attractive investment opportunities

United Parks & Resorts is trading at $49.01 per share, or 10.1x forward P/E. Is now the right time to buy? Find out in our full research report, it’s free.
