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.

Luckily for you, our mission at StockStory is to help you make money and avoid losses by sorting the winners from the losers. That said, here is one mid-cap stock with massive growth potential and two that may have trouble.

Two Mid-Cap Stocks to Sell:

SS&C (SSNC)

Market Cap: $20.87 billion

Founded in 1986 as a bridge between technology and financial services, SS&C Technologies (NASDAQ: SSNC) provides software and software-enabled services that help financial firms and healthcare organizations automate complex business processes.

Why Does SSNC Fall Short?

1. Expenses have increased as a percentage of revenue over the last five years as its adjusted operating margin fell by 1.3 percentage points
2. Capital intensity has ramped up over the last five years as its free cash flow margin decreased by 4.1 percentage points
3. Low returns on capital reflect management’s struggle to allocate funds effectively

SS&C’s stock price of $84.27 implies a valuation ratio of 13.1x forward P/E. Read our free research report to see why you should think twice about including SSNC in your portfolio.

Citizens Financial Group (CFG)

Market Cap: $22.4 billion

Tracing its roots back to 1828 as a community-focused institution, Citizens Financial Group (NYSE: CFG) is a regional bank that provides retail and commercial banking services to individuals, small businesses, and large corporations across 14 states.

Why Are We Wary of CFG?

1. Sales tumbled by 2.2% annually over the last two years, showing market trends are working against its favor during this cycle
2. Annual net interest income growth of 4.5% over the last five years was below our standards for the banking sector
3. Operational productivity has decreased over the last five years as its efficiency ratio worsened by 9.4 percentage points

Citizens Financial Group is trading at $51.84 per share, or 0.9x forward P/B. Check out our free in-depth research report to learn more about why CFG doesn’t pass our bar.

One Mid-Cap Stock to Watch:

Lennox (LII)

Market Cap: $17.61 billion

Based in Texas and founded over a century ago, Lennox (NYSE: LII) is a climate control solutions company offering heating, ventilation, air conditioning, and refrigeration (HVACR) goods.

Why Are We Positive On LII?

1. Excellent operating margin of 17.1% highlights the efficiency of its business model, and its profits increased over the last five years as it scaled
2. Performance over the past two years was turbocharged by share buybacks, which enabled its earnings per share to grow faster than its revenue
3. Industry-leading 52.3% return on capital demonstrates management’s skill in finding high-return investments

At $503.30 per share, Lennox trades at 21.1x forward P/E. Is now the time to initiate a position? Find out in our full research report, it’s free for active Edge members.
