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".

Not all profitable companies are created equal, and that’s why we built StockStory - to help you find the ones that truly shine bright. 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:

RingCentral (RNG)

Trailing 12-Month GAAP Operating Margin: 2.7%

Founded in 1999 during the dot-com era, RingCentral (NYSE: RNG) provides software as a service that unifies phone, text, fax, video calls and chat in one platform.

Why Is RNG Risky?

1. Offerings struggled to generate meaningful interest as its average billings growth of 5% over the last year did not impress
2. Estimated sales growth of 5% for the next 12 months implies demand will slow from its three-year trend
3. Customer acquisition costs take a while to recoup, making it difficult to justify sales and marketing investments that could increase revenue

RingCentral’s stock price of $27.09 implies a valuation ratio of 1x forward price-to-sales. If you’re considering RNG for your portfolio, see our FREE research report to learn more.

THOR Industries (THO)

Trailing 12-Month GAAP Operating Margin: 3.5%

Created through the acquisition and merger of various RV manufacturers, THOR Industries manufactures and sells a range of recreational vehicles, including motorhomes and travel trailers, catering to consumers seeking the freedom and comfort of the RV lifestyle.

Why Do We Steer Clear of THO?

1. Products and services are facing significant end-market challenges during this cycle as sales have declined by 11.4% annually over the last two years
2. Falling earnings per share over the last two years has some investors worried as stock prices ultimately follow EPS over the long term
3. Waning returns on capital imply its previous profit engines are losing steam

THOR Industries is trading at $95.37 per share, or 19.6x forward P/E. Dive into our free research report to see why there are better opportunities than THO.

One Stock to Watch:

Tecnoglass (TGLS)

Trailing 12-Month GAAP Operating Margin: 26.7%

The first-ever Colombian company to trade on the NASDAQ, Tecnoglass (NYSE: TGLS) is a manufacturer of architectural glass, windows, and aluminum products.

Why Do We Like TGLS?

1. Annual revenue growth of 20.3% over the past five years was outstanding, reflecting market share gains this cycle
2. Healthy operating margin of 27.3% shows it’s a well-run company with efficient processes, and it turbocharged its profits by achieving some fixed cost leverage
3. Industry-leading 28.9% return on capital demonstrates management’s skill in finding high-return investments, and its returns are growing as it capitalizes on even better market opportunities

At $77.70 per share, Tecnoglass trades at 17.2x forward P/E. Is now a good time to buy? See for yourself in our comprehensive research report, it’s free.
