3 Mega-Cap Stocks with Exciting Potential

Megacap stocks dominate their sectors and their actions influence economies worldwide. The flip side though is that their sheer size means they have less room for explosive growth as scale works against them.

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 three industry titans whose competitive advantages create flywheel effects.

Costco (COST)

Market Cap: $432.7 billion

Designed to be a one-stop shop for the suburban consumer, Costco (NASDAQ:COST) is a membership-only retail chain that sells groceries, apparel, toys, and household items, often in bulk quantities.

Why Do We Watch COST?

1. Locations open for at least a year are seeing increased demand as same-store sales have averaged 6.6% growth over the past two years
2. Enormous revenue base of $293.6 billion compensates for its low gross margin and provides significant leverage in supplier negotiations
3. ROIC punches in at 35%, illustrating management’s expertise in identifying profitable investments, and its rising returns show it’s making even more lucrative bets

Costco is trading at $966.65 per share, or 45.1x forward P/E. Is now the right time to buy? See for yourself in our comprehensive research report, it’s free.

Philip Morris (PM)

Market Cap: $281.7 billion

Founded in 1847, Philip Morris International (NYSE:PM) manufactures and sells a wide range of tobacco and nicotine-containing products, including cigarettes, heated tobacco products, and oral nicotine pouches.

Why Will PM Beat the Market?

1. Differentiated product offerings are difficult to replicate at scale and result in a best-in-class gross margin of 66.5%
2. Healthy operating margin of 36.5% shows it’s a well-run company with efficient processes
3. PM is a free cash flow machine with the flexibility to invest in growth initiatives or return capital to shareholders

Why Should You Buy V?

1. Annual revenue growth of 15% over the past five years was outstanding, reflecting market share gains this cycle
2. Performance over the past five years was boosted by share buybacks, which enabled its earnings per share to grow faster than its revenue
