1 Safe-and-Steady Stock to Own for Decades and 2 Facing Challenges

ADP Cover Image

Stability is great, but low-volatility stocks may struggle to deliver market-beating returns over time as they sometimes underperform during bull markets.

Choosing the wrong investments can cause you to fall behind, which is why we started StockStory - to separate the winners from the losers. Keeping that in mind, here is one low-volatility stock that could offer consistent gains and two stuck in limbo.

Two Stocks to Sell:

OPENLANE (KAR)

Rolling One-Year Beta: 0.89

Facilitating the sale of approximately 1.3 million used vehicles in 2023, OPENLANE (NYSE: KAR) operates digital marketplaces that connect sellers and buyers of used vehicles across North America and Europe, facilitating wholesale transactions.

Why Do We Think KAR Will Underperform?

  1. Sales tumbled by 5.3% annually over the last five years, showing market trends are working against its favor during this cycle
  2. Underwhelming 2.6% return on capital reflects management’s difficulties in finding profitable growth opportunities
  3. 5× net-debt-to-EBITDA ratio makes lenders less willing to extend additional capital, potentially necessitating dilutive equity offerings

OPENLANE is trading at $28.84 per share, or 31.1x forward P/E. Dive into our free research report to see why there are better opportunities than KAR.

The Hanover Insurance Group (THG)

Rolling One-Year Beta: 0.47

Founded in 1852 during a time when fire insurance was crucial for protecting businesses and homes, The Hanover Insurance Group (NYSE: THG) provides property and casualty insurance products through independent agents, serving individuals, small businesses, and mid-sized companies.

Why Are We Cautious About THG?

  1. Annual revenue growth of 5.4% over the last two years was below our standards for the insurance sector
  2. 5% annualized net premiums earned growth over the last two years lagged behind its insurance peers
  3. 2% annual book value per share growth over the last five years was slower than its insurance peers

At $175.98 per share, The Hanover Insurance Group trades at 1.9x forward P/B. Check out our free in-depth research report to learn more about why THG doesn’t pass our bar.

One Stock to Buy:

ADP (ADP)

Rolling One-Year Beta: 0.62

Processing one out of every six paychecks in the United States, ADP (NASDAQ: ADP) provides cloud-based human capital management solutions that help businesses manage payroll, benefits, talent acquisition, and HR administration.

Why Do We Love ADP?

  1. Solid 7.1% annual revenue growth over the last five years indicates its offering’s solve complex business issues
  2. Impressive free cash flow profitability enables the company to fund new investments or reward investors with share buybacks/dividends, and its growing cash flow gives it even more resources to deploy
  3. Rising returns on capital show management is finding more attractive investment opportunities

ADP’s stock price of $298 implies a valuation ratio of 27.6x forward P/E. Is now a good time to buy? Find out in our full research report, it’s free.
