Expensive stocks typically earn their valuations through superior growth rates that other companies simply can’t match. The flip side though is that these lofty expectations make them particularly susceptible to drawdowns when market sentiment shifts.
Separating true intrinsic value from speculation isn’t easy, especially during bull markets. That’s where StockStory comes in - to help you find high-quality companies that will stand the test of time. That said, here is one high-flying stock expanding its competitive advantage and two with big downside risk.
Two High-Flying Stocks to Sell:
Texas Instruments (TXN)
Forward P/E Ratio: 36.5x
Headquartered in Dallas, Texas since the 1950s, Texas Instruments (NASDAQ: TXN) is the world’s largest producer of analog semiconductors.
Why Are We Cautious About TXN?
- Scale is a double-edged sword because it limits the company’s growth potential compared to its smaller competitors, as reflected in its below-average annual revenue increases of 3.6% for the last five years
- Expenses have increased as a percentage of revenue over the last five years as its operating margin fell by 15.3 percentage points
- 10.4 percentage point decline in its free cash flow margin over the last five years reflects the company’s increased investments to defend its market position
At $309.45 per share, Texas Instruments trades at 36.5x forward P/E. Dive into our free research report to see why there are better opportunities than TXN.
Allegro MicroSystems (ALGM)
Forward P/E Ratio: 52x
The result of a spinoff from Sanken in Japan, Allegro MicroSystems (NASDAQ: ALGM) is a designer of power management chips and distance sensors used in electric vehicles and data centers.
Why Do We Pass on ALGM?
- Products and services are facing significant end-market challenges during this cycle as sales have declined by 7.9% annually over the last two years
- Falling earnings per share over the last five years has some investors worried as stock prices ultimately follow EPS over the long term
- Low free cash flow margin of 9.1% for the last two years gives it little breathing room, constraining its ability to self-fund growth or return capital to shareholders
Allegro MicroSystems’s stock price of $57.69 implies a valuation ratio of 52x forward P/E. If you’re considering ALGM for your portfolio, see our FREE research report to learn more.
One High-Flying Stock to Buy:
American Superconductor (AMSC)
Forward P/E Ratio: 34.4x
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 Are We Bullish on AMSC?
- Market share has increased this cycle as its 43.3% annual revenue growth over the last two years was exceptional
- Free cash flow margin grew by 24.5 percentage points over the last five years, giving the company more chips to play with
- Rising returns on capital show the company is starting to reap the benefits of its past investments
