Mid-cap stocks often strike the right balance between having proven business models and market opportunities that can support $100 billion corporations. However, they face intense competition from scaled industry giants and can be disrupted by new innovative players vying for a slice of the pie.
These dynamics can rattle even the most seasoned professionals, which is why we started StockStory - to help you separate the good companies from the bad. Keeping that in mind, here is one mid-cap stock with massive growth potential and two that may have trouble.
Two Mid-Cap Stocks to Sell:
WESCO (WCC)
Market Cap: $14.23 billion
Based in Pittsburgh, WESCO (NYSE: WCC) provides electrical, industrial, and communications products and augments them with services such as supply chain management.
Why Does WCC Worry Us?
- Organic revenue growth fell short of our benchmarks over the past two years and implies it may need to improve its products, pricing, or go-to-market strategy
- Earnings per share fell by 5.9% annually over the last two years while its revenue grew, showing its incremental sales were much less profitable
- Ability to fund investments or reward shareholders with increased buybacks or dividends is restricted by its weak free cash flow margin of 1.5% for the last five years
WESCO is trading at $292.77 per share, or 17.8x forward P/E. Dive into our free research report to see why there are better opportunities than WCC.
Flex (FLEX)
Market Cap: $26.91 billion
Originally known as Flextronics until its 2016 rebranding, Flex (NASDAQ: FLEX) is a global manufacturing partner that designs, engineers, and builds products for companies across industries from medical devices to solar trackers.
Why Are We Wary of FLEX?
- Sales stagnated over the last two years and signal the need for new growth strategies
- Low free cash flow margin of 2.8% for the last five years gives it little breathing room, constraining its ability to self-fund growth or return capital to shareholders
- Shrinking returns on capital suggest that increasing competition is eating into the company’s profitability
Flex’s stock price of $73.85 implies a valuation ratio of 19.4x forward P/E. To fully understand why you should be careful with FLEX, check out our full research report (it’s free).
One Mid-Cap Stock to Buy:
Super Micro (SMCI)
Market Cap: $14.03 billion
Founded in Silicon Valley in 1993 and known for its modular "building block" approach to server design, Super Micro Computer (NASDAQ: SMCI) designs and manufactures high-performance, energy-efficient server and storage systems for data centers, cloud computing, AI, and edge computing applications.
Why Do We Love SMCI?
- Annual revenue growth of 74.1% over the last two years was superb and indicates its market share increased during this cycle
- Earnings per share grew by 45.5% annually over the last five years, massively outpacing its peers
- Free cash flow turned positive over the last five years, showing the company has crossed a key inflection point
At $23.30 per share, Super Micro trades at 9.2x forward P/E. Is now a good time to buy? Find out in our full research report, it’s free.
