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. Keeping that in mind, here is one profitable company that leverages its financial strength to beat the competition and two best left off your watchlist.

Two Stocks to Sell:

Vishay Intertechnology (VSH)

Trailing 12-Month GAAP Operating Margin: 1.9%

Named after the founder's ancestral village in present-day Lithuania, Vishay Intertechnology (NYSE: VSH) manufactures simple chips and electronic components that are building blocks of virtually all types of electronic devices.

Why Is VSH Risky?

1. Customers postponed purchases of its products and services this cycle as its revenue declined by 5% annually over the last two years
2. High input costs result in an inferior gross margin of 20.3% that must be offset through higher volumes
3. Cash-burning history and the downward spiral in its margin profile make us wonder if it has a viable business model

At $17.63 per share, Vishay Intertechnology trades at 31.2x forward P/E. Check out our free in-depth research report to learn more about why VSH doesn’t pass our bar.

Comcast (CMCSA)

Trailing 12-Month GAAP Operating Margin: 16.7%

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

Why Do We Pass on CMCSA?

1. Demand for its offerings was relatively low as its number of domestic broadband customers has underwhelmed
2. Capital intensity will likely increase as its free cash flow margin is anticipated to drop by 4.4 percentage points over the next year
3. Rising returns on capital show management is making relatively better investments

Comcast is trading at $28.74 per share, or 8x forward P/E. Read our free research report to see why you should think twice about including CMCSA in your portfolio.

One Stock to Buy:

Armstrong World (AWI)

Trailing 12-Month GAAP Operating Margin: 26.6%

Started as a two-man shop dating back to the 1860s, Armstrong (NYSE: AWI) provides ceiling and wall products to commercial and residential spaces.

Why Should You Buy AWI?

1. Impressive 11.9% annual revenue growth over the last two years indicates it’s winning market share this cycle
2. Share repurchases over the last two years enabled its annual earnings per share growth of 18% to outpace its revenue gains
3. Free cash flow margin increased by 5.5 percentage points over the last five years, giving the company more capital to invest or return to shareholders

Armstrong World’s stock price of $164.93 implies a valuation ratio of 20.1x forward P/E. Is now the time to initiate a position? See for yourself in our comprehensive research report, it’s free.
