Expensive stocks often command premium valuations because the market thinks their business models are exceptional. However, the downside is that high expectations are already baked into their prices, leaving little room for error if they stumble even slightly.
Finding the right balance between price and quality can challenge even the most skilled investors. Luckily for you, we started StockStory to help you identify the real opportunities. Keeping that in mind, here is one high-flying stock expanding its competitive advantage and two with big downside risk.
Two High-Flying Stocks to Sell:
Ducommun (DCO)
Forward P/E Ratio: 33.4x
California’s oldest company, Ducommun (NYSE:DCO) is a provider of engineering and manufacturing services for high-performance products primarily within the aerospace and defense industries.
Why Should You Dump DCO?
- Demand cratered as it couldn’t win new orders over the past two years, leading to an average 16% decline in its backlog
- Efficiency has decreased over the last five years as its operating margin fell by 11.5 percentage points
- Investment activity picked up over the last five years, pressuring its weak free cash flow margin of -0.6%
Ducommun’s stock price of $146.94 implies a valuation ratio of 33.4x forward P/E. Dive into our free research report to see why there are better opportunities than DCO.
LeMaitre (LMAT)
Forward P/E Ratio: 36.6x
Founded in 1983 and named after a pioneering vascular surgeon, LeMaitre Vascular (NASDAQGM:LMAT) develops and manufactures specialized medical devices used by vascular surgeons to treat peripheral vascular disease and other circulatory conditions.
Why Does LMAT Give Us Pause?
- Smaller revenue base of $256.3 million means it hasn’t achieved the economies of scale that some industry juggernauts enjoy
LeMaitre is trading at $110.08 per share, or 36.6x forward P/E. Read our free research report to see why you should think twice about including LMAT in your portfolio.
One High-Flying Stock to Buy:
American Superconductor (AMSC)
Forward P/E Ratio: 58.9x
Founded in 1987, American Superconductor (NASDAQ:AMSC) has shifted from superconductor research to developing power systems, adapting to changing energy grid needs and naval technology requirements.
Why Do We Love AMSC?
- Market share has increased this cycle as its 43.7% annual revenue growth over the last two years was exceptional
- Free cash flow flipped to positive over the last five years, indicating the company has achieved financial self-sustainability
- Improving returns on capital suggest its past investments are beginning to deliver value
At $56.78 per share, American Superconductor trades at 58.9x forward P/E. Is now the time to initiate a position? See for yourself in our full research report, it’s free.
