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. That said, here are two mid-cap stocks with huge upside potential and one best left ignored.

One Mid-Cap Stock to Sell:

Fortive (FTV)

Market Cap: $17.55 billion

Taking its name from the Latin root of "strong", Fortive (NYSE: FTV) manufactures products and develops industrial software for numerous industries.

Why Do We Think FTV Will Underperform?

1. Core business is underperforming as its organic revenue has disappointed over the past two years, suggesting it might need acquisitions to stimulate growth
2. Earnings per share were flat over the last five years and fell short of the peer group average
3. Underwhelming 5.5% return on capital reflects management’s difficulties in finding profitable growth opportunities, and its falling returns suggest its earlier profit pools are drying up

At $55.91 per share, Fortive trades at 19.8x forward P/E. To fully understand why you should be careful with FTV, check out our full research report (it’s free).

Two Mid-Cap Stocks to Watch:

MACOM (MTSI)

Market Cap: $17.93 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 Are We Fans of MTSI?

2. Offerings are difficult to replicate at scale and result in a stellar 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
