Stocks trading between $10 and $50 can be particularly interesting as they frequently represent businesses that have survived their early challenges. However, investors should remain vigilant as some may still have unproven business models, leaving them vulnerable to the ebbs and flows of the broader market.
This is precisely where StockStory comes in - we do the heavy lifting to identify companies with solid fundamentals so you can invest with confidence. Keeping that in mind, here are three stocks under $50 to avoid and some other investments you should consider instead.
Sensata Technologies (ST)
Share Price: $41.63
Originally a temperature sensor control maker and a subsidiary of Texas Instruments for 60 years, Sensata Technology Holdings (NYSE: ST) is a leading supplier of analog sensors used in industrial and transportation applications, best known for its dominant position in the tire pressure monitoring systems in cars.
Why Do We Pass on ST?
- Sales tumbled by 3.3% annually over the last two years, showing market trends are working against it during this cycle
- Demand will likely be soft over the next 12 months as Wall Street’s estimates imply tepid growth of 4.3%
- Gross margin of 29.1% reflects its high production costs
At $41.63 per share, Sensata Technologies trades at 10.8x forward P/E. To fully understand why you should be careful with ST, check out our full research report (it’s free).
CSX (CSX)
Share Price: $46.89
Established as part of the Chessie System and Seaboard Coast Line Industries merger, CSX (NASDAQ: CSX) is a transportation company specializing in freight rail services.
Why Do We Think CSX Will Underperform?
- Disappointing unit sales over the past two years imply it may need to invest in improvements to get back on track
- Flat earnings per share over the last two years underperformed the sector average
- Free cash flow margin dropped by 6.2 percentage points over the last five years, implying the company became more capital intensive as competition picked up
CSX is trading at $46.89 per share, or 21.9x forward P/E. If you’re considering CSX for your portfolio, see our FREE research report to learn more.
Amphastar Pharmaceuticals (AMPH)
Share Price: $25.83
Founded in 1996 and known for its expertise in complex drug formulations, Amphastar Pharmaceuticals (NASDAQ: AMPH) develops and manufactures technically challenging injectable and inhalation medications, including both generic and proprietary pharmaceutical products.
Why Are We Hesitant About AMPH?
- Sales trends were unexciting over the last two years as its 1.2% annual growth was below the typical healthcare company
- Smaller revenue base of $730 million means it hasn’t achieved the economies of scale that some industry juggernauts enjoy
- Costs have risen faster than its revenue over the last two years, causing its adjusted operating margin to decline by 12.7 percentage points
Amphastar Pharmaceuticals’s stock price of $25.83 implies a valuation ratio of 8.4x forward P/E. Read our free research report to see why you should think twice about including AMPH in your portfolio.
