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.
Even among blue-chip stocks, not all investments are created equal - which is why we built StockStory to help you navigate the market. Keeping that in mind, here is one S&P 500 stock that could deliver good returns and two best left off your watchlist.
Two Stocks to Sell:
Hilton (HLT)
Market Cap: $72.53 billion
Founded in 1919, Hilton Worldwide (NYSE: HLT) is a global hospitality company with a portfolio of hotel brands.
Why Do We Think HLT Will Underperform?
- Revenue per room has disappointed over the past two years due to weaker trends in its daily rates and occupancy levels
- Subpar operating margin of 22.1% constrains its ability to invest in process improvements or effectively respond to new competitive threats
- Free cash flow margin is not anticipated to grow over the next year
Hilton’s stock price of $318.42 implies a valuation ratio of 35.2x forward P/E. If you’re considering HLT for your portfolio, see our FREE research report to learn more.
Gilead Sciences (GILD)
Market Cap: $163.4 billion
From its groundbreaking work in developing the first single-tablet regimens for HIV treatment, Gilead Sciences (NASDAQ: GILD) develops and markets innovative medicines for life-threatening diseases including HIV, viral hepatitis, COVID-19, and cancer.
Why Are We Wary of GILD?
- The company has faced growth challenges as its 3.6% annual revenue increases over the last five years fell short of other healthcare companies
- Free cash flow margin shrank by 7.5 percentage points over the last five years, suggesting the company is consuming more capital to stay competitive
- Diminishing returns on capital suggest its earlier profit pools are drying up
Gilead Sciences is trading at $132.70 per share, or 15.3x forward P/E. Dive into our free research report to see why there are better opportunities than GILD.
One Stock to Buy:
Quanta (PWR)
Market Cap: $111.4 billion
A construction engineering services company, Quanta (NYSE: PWR) provides infrastructure solutions to a variety of sectors, including energy and communications.
Why Will PWR Outperform?
- Average backlog growth of 21.2% over the past two years shows it has a steady sales pipeline that will drive future orders
- Market share will likely rise over the next 12 months as its expected revenue growth of 18.7% is robust
- Earnings growth has massively outpaced its peers over the last two years as its EPS has compounded at 26% annually
At $743.60 per share, Quanta trades at 51.2x forward P/E. Is now the right time to buy? Find out in our full research report, it’s free.
