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 generates reliable profits without sacrificing growth and two that may struggle to keep up.

Two Stocks to Sell:

Paylocity (PCTY)

Trailing 12-Month GAAP Operating Margin: 21.8%

Operating in a field where companies traditionally juggled multiple disconnected systems, Paylocity (NASDAQ: PCTY) provides cloud-based human capital management and payroll software solutions that help businesses manage their workforce and HR processes.

Why Does PCTY Give Us Pause?

1. Underwhelming ARR growth of 12.2% over the last year suggests the company faced challenges in acquiring and retaining long-term customers
2. Estimated sales growth of 6.7% for the next 12 months implies demand will slow from its two-year trend
3. Operating margin improvement of 2.7 percentage points over the last year demonstrates its ability to scale efficiently

Paylocity’s stock price of $145.63 implies a valuation ratio of 4.3x forward price-to-sales. Read our free research report to see why you should think twice about including PCTY in your portfolio.

AMC Networks (AMCX)

Trailing 12-Month GAAP Operating Margin: 2.3%

Originally the joint-venture of four cable television companies, AMC Networks (NASDAQ: AMCX) is a broadcaster producing a diverse range of television shows and movies.

Why Are We Out on AMCX?

1. Products and services have few die-hard fans as sales have declined by 5% annually over the last five years
2. Low free cash flow margin of 10.3% for the last two years gives it little breathing room, constraining its ability to self-fund growth or return capital to shareholders
3. Shrinking returns on capital from an already weak position reveal that neither previous nor ongoing investments are yielding the desired results

AMC Networks is trading at $11.85 per share, or 2.9x forward P/E. To fully understand why you should be careful with AMCX, check out our full research report (it’s free).

One Stock to Buy:

APi (APG)

Trailing 12-Month GAAP Operating Margin: 7.2%

Started in 1926 as an insulation contractor, APi (NYSE: APG) provides life safety solutions and specialty services for buildings and infrastructure.

Why Do We Love APG?

1. Market share has increased this cycle as its 18.5% annual revenue growth over the last five years was exceptional
2. Incremental sales over the last two years have been highly profitable as its earnings per share increased by 17.5% annually, topping its revenue gains
3. Free cash flow margin expanded by 7.2 percentage points over the last five years, providing additional flexibility for investments and share buybacks/dividends

At $41.58 per share, APi trades at 22.7x forward P/E. Is now a good time to buy? Find out in our full research report, it’s free.
