2 Mid-Cap Stocks Worth Your Attention and 1 We Brush Off

Many investors pay attention to mid-cap stocks because they have established business models and expansive market opportunities. However, their paths to becoming $100 billion corporations are ripe with competition, ranging from giants with vast resources to agile upstarts eager to disrupt the status quo.

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 long growth runways and one that could be down big.

One Mid-Cap Stock to Sell:

Masco (MAS)

Market Cap: $14.74 billion

Headquartered just outside of Detroit, MI, Masco (NYSE:MAS) designs and manufactures home-building products such as glass shower doors, decorative lighting, bathtubs, and faucets.

Why Do We Think MAS 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. Flat earnings per share over the last two years underperformed the sector average

3. Diminishing returns on capital suggest its earlier profit pools are drying up

Masco is trading at $72.40 per share, or 17.1x forward P/E. Dive into our free research report to see why there are better opportunities than MAS.
