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. 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:
Assurant (AIZ)
Market Cap: $11.68 billion
With roots dating back to 1892 when it was founded by a Civil War veteran, Assurant (NYSE: AIZ) provides specialized insurance products and services that protect major consumer purchases like mobile devices, vehicles, homes, and appliances.
Why Does AIZ Worry Us?
- 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 5.1% for the last five years
- Scale presents growth limitations compared to smaller competitors, evidenced by its below-average 4.6% annualized growth in net premiums earned for the last five years
- Large asset base makes it harder to grow book value per share quickly, and its annual book value per share growth of 2.7% over the last five years was below our standards for the insurance sector
Assurant’s stock price of $233.39 implies a valuation ratio of 2x forward P/B. To fully understand why you should be careful with AIZ, check out our full research report (it’s free for active Edge members).
Two Stocks to Buy:
The Trade Desk (TTD)
Market Cap: $17.72 billion
Built as an alternative to "walled garden" advertising ecosystems, The Trade Desk (NASDAQ: TTD) provides a cloud-based platform that helps advertisers and agencies plan, manage, and optimize digital advertising campaigns across multiple channels and devices.
Why Are We Bullish on TTD?
- Average billings growth of 20.1% over the last year enhances its liquidity and shows there is steady demand for its products
- User-friendly software enables clients to ramp up spending quickly, leading to the speedy recovery of customer acquisition costs
- Disciplined cost controls and effective management resulted in a strong trailing 12-month operating margin of 18.9%, and its rise over the last year was fueled by some leverage on its fixed costs
At $36.60 per share, The Trade Desk trades at 5.6x forward price-to-sales. Is now a good time to buy? See for yourself in our comprehensive research report, it’s free for active Edge members .
Moody's (MCO)
Market Cap: $87.95 billion
Founded in 1900 during America's railroad boom when investors needed reliable information on bond risks, Moody's (NYSE: MCO) provides credit ratings, risk assessment tools, and analytical solutions that help organizations evaluate financial risks and make informed investment decisions.
Why Do We Love MCO?
