Mid-cap stocks have the best odds of scaling into $100 billion corporations thanks to their tested business models and large addressable markets. But the many opportunities in front of them attract significant competition, spanning from industry behemoths with seemingly infinite resources to small, nimble players with chips on their shoulders.

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 best left ignored.

Two Mid-Cap Stocks to Sell:

Solventum (SOLV)

Market Cap: $11.48 billion

Founded in 1985, Solventum (NYSE: SOLV) develops, manufactures, and commercializes a portfolio of healthcare products and services addressing critical customer and therapeutic patient needs.

Why Is SOLV Risky?

1. Absence of organic revenue growth over the past two years suggests it may have to lean into acquisitions to drive its expansion
2. Performance over the past three years shows each sale was less profitable, as its earnings per share fell by 31.6% annually
3. Free cash flow margin shrank by 26.7 percentage points over the last four years, suggesting the company is consuming more capital to stay competitive

Solventum’s stock price of $66.18 implies a valuation ratio of 10.1x forward P/E. Read our free research report to see why you should think twice about including SOLV in your portfolio.

HP (HPQ)

Market Cap: $16.81 billion

Born from the legendary Silicon Valley garage startup founded by Bill Hewlett and Dave Packard in 1939, HP (NYSE: HPQ) designs and sells personal computers, printers, and related technology products and services to consumers, businesses, and enterprises worldwide.

Why Do We Pass on HPQ?

1. Sales were flat over the last five years, indicating it’s failed to expand this cycle
2. Incremental sales over the last two years were much less profitable as its earnings per share fell by 2.6% annually while its revenue grew
3. Eroding returns on capital suggest its historical profit centers are aging

HP is trading at $18.40 per share, or 7x forward P/E. If you’re considering HPQ for your portfolio, see our FREE research report to learn more.

One Mid-Cap Stock to Watch:

MACOM (MTSI)

Market Cap: $18.58 billion

Founded in the 1950s as Microwave Associates, a communications supplier to the US Army Signal Corp, today MACOM Technology Solutions (NASDAQ: MTSI) is a provider of analog chips used in optical, wireless, and satellite networks.

Why Do We Like MTSI?

1. Annual revenue growth of 27.8% over the last two years was superb and indicates its market share increased during this cycle
2. Offerings are mission-critical for businesses and result in a top-tier gross margin of 54.5%
3. Earnings growth has comfortably beaten the peer group average over the last five years as its EPS has compounded at 22.2% annually

At $250.65 per share, MACOM trades at 52.1x forward P/E. Is now the right time to buy? See for yourself in our full research report, it’s free.
