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 are two S&P 500 stocks that could deliver good returns and one that may struggle.
One Stock to Sell:
Conagra (CAG)
Market Cap: $6.54 billion
Founded in 1919 as Nebraska Consolidated Mills in Omaha, Nebraska, Conagra Brands today (NYSE: CAG) boasts a diverse portfolio of packaged foods brands that includes everything from whipped cream to jarred pickles to frozen meals.
Why Should You Sell CAG?
- Declining unit sales over the past two years suggest it might have to lower prices to stimulate growth
- Performance over the past three years shows each sale was less profitable as its earnings per share dropped by 13.8% annually, worse than its revenue
- Free cash flow margin shrank by 4.8 percentage points over the last year, suggesting the company is consuming more capital to stay competitive
Conagra is trading at $13.72 per share, or 8.3x forward P/E. If you’re considering CAG for your portfolio, see our FREE research report to learn more.
Two Stocks to Watch:
Microsoft (MSFT)
Market Cap: $3.04 trillion
Originally named "Micro-soft" for microcomputer software when founded in 1975, Microsoft (NASDAQ: MSFT) is a global technology company that develops software, cloud services, devices, and AI solutions for consumers, businesses, and organizations worldwide.
Why Is MSFT a Top Pick?
- Microsoft is one of the great brands not just in tech but all of business. It produces mission-critical software and bundles it together, resulting in cream-of-the-crop gross margins.
- The company's elite unit economics lead to robust profit margins that improve over time. This speaks to the scale advantages and operating efficiency across its diverse portfolio, which spans everything from Office and Azure to Minecraft.
- Microsoft has a virtuous cycle of returns. Its dominant market position enables it to generate strong free cash flow, and it reinvests these funds into promising ventures that further strengthen its competitive moat.
