"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.

These trade-offs can cause headaches for even the most seasoned professionals, which is why we started StockStory - to help you find high-quality companies that can grow their earnings no matter what. That said, here are two industry titans whose competitive advantages create flywheel effects and one whose momentum may slow.

One Mega-Cap Stock to Sell:

Walmart (WMT)

Market Cap: $782.5 billion

Known for its large-format Supercenters, Walmart (NYSE:WMT) is a retail pioneer that serves a budget-conscious consumer who is looking for a wide range of products under one roof.

Why Are We Hesitant About WMT?

Sizable revenue base leads to growth challenges as its 4.8% annual revenue increases over the last six years fell short of other consumer retail companies Widely-available products (and therefore stiff competition) result in an inferior gross margin of 24.7% that must be offset through higher volumes Performance over the past six years shows its incremental sales were much less profitable, as its earnings per share fell by 10.9% annually

At $97.68 per share, Walmart trades at 36.6x forward P/E. Check out our free in-depth research report to learn more about why WMT doesn’t pass our bar.

Two Mega-Cap Stocks to Watch:

Apple (AAPL)

Market Cap: $3.09 trillion

Creator of the iPhone and App Store, Apple (NASDAQ:AAPL) is a legendary developer of consumer electronics and software.

Why Do We Like AAPL?

Apple's revenue base is so large because nearly everyone in the U.S. has an iPhone, but this is a double-edged sword. Growth must now come from upgrades, a harder pitch that has resulted in sluggish top-line performance recently. Still, Apple's devices have endured for decades, speaking to its brand, design ethos, and technological chops. Its success is rare in the world of consumer electronics, which is fraught because of commoditization, competition, and obsolescence risk. The company may not have the best gross margin because of its hardware orientation, but it still manages to produce elite operating and free cash flow margins. This shows it doesn’t need over-the-top marketing campaigns to convince people to buy its products.

Apple’s stock price of $206.60 implies a valuation ratio of 27.6x forward price-to-earnings. Is now a good time to buy? Find out in our full research report, it’s free.
