"Too big to fail" is how we would describe the megacap stocks in this article today. While they will likely stand the test of time, it’s not all sunshine and rainbows as their scale can limit their ability to find new sources of growth.
This dynamic can trouble even the most skilled investors, but luckily for you, we started StockStory to help you navigate these trade-offs and uncover exceptional companies that break the mold. Keeping that in mind, here are two industry titans that still have big upside potential and one that could be stalling.
One Mega-Cap Stock to Sell:
Tesla (TSLA)
Market Cap: $1.55 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 Should You Sell TSLA?
- 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.
- 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.
- 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.
At $409.04 per share, Tesla trades at 184x forward price-to-earnings. If you’re considering TSLA for your portfolio, see our FREE research report to learn more.
Two Mega-Cap Stocks to Watch:
AMD (AMD)
Market Cap: $666 billion
Founded in 1969 by a group of former Fairchild semiconductor executives led by Jerry Sanders, Advanced Micro Devices (NASDAQ:AMD) is one of the leading designers of computer processors and graphics chips used in PCs and data centers.
Why Will AMD Beat the Market?
- Impressive 26.8% annual revenue growth over the last five years indicates it’s winning market share this cycle
- Demand for the next 12 months is expected to accelerate above its two-year trend as Wall Street forecasts robust revenue growth of 47.4%
- Earnings growth has comfortably beaten the peer group average over the last five years as its EPS has compounded at 23% annually
AMD is trading at $407.71 per share, or 48.5x forward P/E. Is now the right time to buy? See for yourself in our in-depth research report, it’s free.
Caterpillar (CAT)
Market Cap: $412.5 billion
With its iconic yellow machinery working on construction sites, Caterpillar (NYSE:CAT) manufactures construction equipment like bulldozers, excavators, and parts and maintenance services.
Why Is CAT on Our Radar?
- Healthy operating margin of 16.9% shows it’s a well-run company with efficient processes, and its rise over the last five years was fueled by some leverage on its fixed costs
- Free cash flow margin expanded by 5 percentage points over the last five years, providing additional flexibility for investments and share buybacks/dividends
- Industry-leading 36.6% return on capital demonstrates management’s skill in finding high-return investments
Caterpillar’s stock price of $893.38 implies a valuation ratio of 37x forward P/E. Is now the time to initiate a position? Find out in our full research report, it’s free.
