1 S&P 500 Stock for Long-Term Investors and 2 We Ignore

The S&P 500 (^GSPC) is often seen as a benchmark for strong businesses, but that doesn’t mean every stock is worth owning. Some companies face significant challenges, whether it’s stagnating growth, heavy debt, or disruptive new competitors.

Even among blue-chip stocks, not all investments are created equal - which is why we built StockStory to help you navigate the market. That said, here is one S&P 500 stock that could deliver good returns and two that could be in trouble.

Two Stocks to Sell:

A. O. Smith (AOS)

Market Cap: $10.68 billion

Credited with the invention of the glass-lined water heater, A.O. Smith (NYSE:AOS) manufactures water heating and treatment products for various industries.

Why Is AOS Not Exciting?

1. Sales were flat over the last two years, indicating it’s failed to expand this cycle
2. Projected sales growth of 3.6% for the next 12 months suggests sluggish demand
3. Earnings growth underperformed the sector average over the last two years as its EPS grew by just 2.2% annually

A. O. Smith’s stock price of $75.81 implies a valuation ratio of 19.2x forward P/E.

Tesla (TSLA)

Market Cap: $1.54 trillion

Originally founded by Martin Eberhard and Marc Tarpenning in 2003, Tesla (NASDAQ:TSLA) is an electric vehicle company accelerating the world’s transition to sustainable energy.

Why Do We Steer Clear of TSLA?

1. Tesla's scale advantage in EV production leads to gross margins that exceed incumbents such as General Motors and Ford. However, a softer macroeconomic backdrop and tariff pressures have weighed on automobile sales, which are highly cyclical.
2. The company's execution ability is a question mark given its long history of delays, such as the Cybertruck and Robotaxi launches. Its sizeable investments in projects with uncertain return timelines, like Optimus, also raise skepticism from investors.
3. On the bright side, Tesla's Megapack product solves a critical problem for utilities needing renewable energy storage solutions. This innovation has made the energy segment the most profitable and fastest-growing business line for the company.

Tesla is trading at $415.65 per share, or 205.2x forward price-to-earnings.

One Stock to Watch:

Elevance Health (ELV)

Market Cap: $72.2 billion

Formerly known as Anthem until its 2022 rebranding, Elevance Health (NYSE:ELV) is one of America's largest health insurers, serving approximately 47 million medical members through its network-based managed care plans.

Why Are We Fans of ELV?

1. Annual revenue growth of 10.3% over the last five years was above the sector average and underscores its products and services value to customers
2. Unparalleled scale of $197.6 billion in revenue enables it to spread administrative costs across a larger membership base
3. Stellar returns on capital showcase management’s ability to surface highly profitable business ventures

At $333.67 per share, Elevance Health trades at 12.6x forward P/E. Is now a good time to buy?
