1 S&P 500 Stock for Long-Term Investors and 2 We Turn Down

GOOGL Cover Image

The S&P 500 (^GSPC) is home to the biggest and most well-known companies in the market, making it a go-to index for investors seeking stability. But not all large-cap stocks are created equal - some are struggling with slowing growth, declining margins, or increased competition.

Even among blue-chip stocks, not all investments are created equal - which is why we built StockStory to help you navigate the market. That said, here is one S&P 500 stock that could deliver good returns and two best left off your watchlist.

Two Stocks to Sell:

Avery Dennison (AVY)

Market Cap: $13.34 billion

Founded as Kum Kleen Products, Avery Dennison (NYSE: AVY) is a manufacturer of adhesive materials, display graphics, and packaging products, serving various industries.

Why Does AVY Give Us Pause?

  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. Free cash flow margin shrank by 3.4 percentage points over the last five years, suggesting the company is consuming more capital to stay competitive
  3. Diminishing returns on capital suggest its earlier profit pools are drying up

Avery Dennison’s stock price of $171.08 implies a valuation ratio of 16.6x forward P/E. Check out our free in-depth research report to learn more about why AVY doesn’t pass our bar.

Cincinnati Financial (CINF)

Market Cap: $23.99 billion

Founded in 1950 by independent insurance agents seeking stable market options for their clients, Cincinnati Financial (NASDAQ: CINF) provides property casualty insurance, life insurance, and related financial services through independent agencies across 46 states.

Why Does CINF Fall Short?

  1. Scale is a double-edged sword because it limits the company’s growth potential compared to its smaller competitors, as reflected in its below-average annual revenue increases of 6.8% for the last five years
  2. Expenses have increased as a percentage of revenue over the last four years as its combined ratio degraded by 8.4 percentage points
  3. Estimated book value per share growth of 2.8% for the next 12 months implies profitability will slow from its two-year trend

At $153.40 per share, Cincinnati Financial trades at 1.7x forward P/B. Dive into our free research report to see why there are better opportunities than CINF.

One Stock to Buy:

Alphabet (GOOGL)

Market Cap: $2.56 trillion

Started by Stanford students Larry Page and Sergey Brin in a Menlo Park garage, Alphabet (NASDAQ: GOOGL) is the parent company of the eponymous Google Search engine, Google Cloud Platform, and YouTube.

Why Will GOOGL Outperform?

  1. Alphabet’s dominant Google Search sits on the pantheon of the best businesses ever. This is reflected in its robust long-term revenue growth and elite operating margin.
  2. The company’s profit margins have become even higher over time, speaking to its scale advantages and operating efficiency not only in its core Search business but also in Google Cloud Platform and YouTube.
  3. Revenue growth and increasing operating margins are the key ingredients for strong EPS growth. Google has these, and when also factoring in its share repurchases, you can see why EPS has exploded over the long term.

Alphabet is trading at $211.46 per share, or 22x forward price-to-earnings. Is now the right time to buy? Find out in our full research report, it’s free.
