1 S&P 500 Stock with Competitive Advantages and 2 We Turn Down

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.

Some large-cap stocks are past their peak, and StockStory is here to help you separate the winners from the laggards. Keeping that in mind, here is one S&P 500 stock that is leading the market forward and two best left off your watchlist.

Two Stocks to Sell:

Vulcan Materials (VMC)

Market Cap: $39.55 billion

Founded in 1909, Vulcan Materials (NYSE:VMC) is a producer of construction aggregates, primarily crushed stone, sand, and gravel.

Why Are We Cautious About VMC?

1. Performance surrounding its tons shipped has lagged its peers
2. Demand will likely be soft over the next 12 months as Wall Street’s estimates imply tepid growth of 2.1%
3. Gross margin of 25.2% is below its competitors, leaving less money to invest in areas like marketing and R&D

Vulcan Materials’s stock price of $299.50 implies a valuation ratio of 32.1x forward P/E. To fully understand why you should be careful with VMC, check out our full research report (it’s free).

Solventum (SOLV)

Market Cap: $12.99 billion

Founded in 1985, Solventum (NYSE:SOLV) develops, manufactures, and commercializes a portfolio of healthcare products and services addressing critical customer and therapeutic patient needs.

Why Do We Think SOLV Will Underperform?

1. Absence of organic revenue growth over the past two years suggests it may have to lean into acquisitions to drive its expansion
2. Estimated sales decline of 5.2% for the next 12 months implies a challenging demand environment
3. 30.1 percentage point decline in its free cash flow margin over the last four years reflects the company’s increased investments to defend its market position

At $75.82 per share, Solventum trades at 11.9x forward P/E. Read our free research report to see why you should think twice about including SOLV in your portfolio.

One Stock to Watch:

Vertex Pharmaceuticals (VRTX)

Market Cap: $119.5 billion

Founded in 1989 with a mission to create medicines that treat the underlying causes of disease rather than just symptoms, Vertex Pharmaceuticals (NASDAQ:VRTX) develops and markets transformative medicines for serious diseases, with a focus on cystic fibrosis, sickle cell disease, and pain management.

Why Should VRTX Be on Your Watchlist?

1. Offerings and unique value proposition resonate with customers, as seen in its above-market 14.1% annual sales growth over the last five years
2. Impressive free cash flow profitability enables the company to fund new investments or reward investors with share buybacks/dividends
3. Stellar returns on capital showcase management’s ability to surface highly profitable business ventures

Vertex Pharmaceuticals is trading at $470.36 per share, or 24.9x forward P/E. Is now the right time to buy? Find out in our full research report, it’s free.
