3 S&P 500 Stocks We Think Twice About

MAS Cover Image

While the S&P 500 (^GSPC) includes industry leaders, not every stock in the index is a winner. Some companies are past their prime, weighed down by poor execution, weak financials, or structural headwinds.

Some large-cap stocks are past their peak, and StockStory is here to help you separate the winners from the laggards. That said, here are three S&P 500 stocks that don’t make the cut and some better choices instead.

Masco (MAS)

Market Cap: $15.29 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 Avoid MAS?

  1. Absence of organic revenue growth over the past two years suggests it may have to lean into acquisitions to drive its expansion
  2. Anticipated sales growth of 1.3% for the next year implies demand will be shaky
  3. Diminishing returns on capital suggest its earlier profit pools are drying up

At $73.88 per share, Masco trades at 19.7x forward P/E. To fully understand why you should be careful with MAS, check out our full research report (it’s free).

Corning (GLW)

Market Cap: $55.34 billion

Supplying windows for some of the United States’s earliest spacecraft, Corning (NYSE: GLW) provides glass and other electronic components for the consumer electronics, telecommunications, automotive, and healthcare industries.

Why Are We Wary of GLW?

  1. Sizable revenue base leads to growth challenges as its 4% annual revenue increases over the last two years fell short of other industrials companies
  2. 4.1 percentage point decline in its free cash flow margin over the last five years reflects the company’s increased investments to defend its market position
  3. Below-average returns on capital indicate management struggled to find compelling investment opportunities, and its falling returns suggest its earlier profit pools are drying up

Corning’s stock price of $64.60 implies a valuation ratio of 25.9x forward P/E. Read our free research report to see why you should think twice about including GLW in your portfolio.

GE HealthCare (GEHC)

Market Cap: $33.73 billion

Spun off from industrial giant General Electric in 2023 after over a century as its healthcare division, GE HealthCare (NASDAQ: GEHC) provides medical imaging equipment, patient monitoring systems, diagnostic pharmaceuticals, and AI-enabled healthcare solutions to hospitals and clinics worldwide.

Why Does GEHC Worry Us?

  1. Organic revenue growth fell short of our benchmarks over the past two years and implies it may need to improve its products, pricing, or go-to-market strategy
  2. Performance over the past four years shows its incremental sales were much less profitable, as its earnings per share fell by 3.7% annually
  3. Free cash flow margin dropped by 9.6 percentage points over the last five years, implying the company became more capital intensive as competition picked up

GE HealthCare is trading at $74 per share, or 17.9x forward P/E. If you’re considering GEHC for your portfolio, see our FREE research report to learn more.
