3 Monster Stocks to Hold for the Next 20 Years

Every investor dreams of finding that one stock they can buy, tuck into their portfolio, and forget about for decades -- the kind of company that just keeps compounding wealth through recessions, market panics, and everything in between.

Well, I'm going to give you three. These are consumer goods titans with global reach, proven business models, and recent 2026 updates that show their businesses are accelerating.

If you have a 20-year time horizon, these three stocks deserve a serious look.

1. Costco Wholesale

If there's a retailer built to last two more decades, it's Costco Wholesale (NASDAQ: COST). The warehouse giant just reported January 2026 net sales of $21.33 billion, a 9.3% year-over-year increase, with comparable sales climbing 7.5% when you strip out gas and currency effects. What's honestly bonkers to me is that Costco's e-commerce sales jumped more than 34% over the holidays. That's not the kind of growth you see from a typically in-person shopping company that's running out of steam.

But the magic of Costco has always been its membership model -- and right now, that flywheel is spinning faster than ever. In the first quarter of fiscal 2026, membership fee income surged 14% to $1.329 billion. The paid membership base hit 81.4 million, up 5.2%, with executive memberships -- Costco's most profitable tier -- growing 9.1% to 39.7 million.

Executive members now account for a staggering 74.3% of total sales.

Here's what makes this a 20-year hold: Costco's model gets stronger with scale. More members mean more buying power, lower prices, and higher renewal rates. It's a virtuous cycle that competitors simply cannot replicate.

With 921 warehouses globally and an expanding digital business, there's a long runway of international growth still ahead. The company isn't slowing down. It's just getting started in markets like China, where the potential is enormous.​

2. The Coca-Cola Company

Coca-Cola (NYSE: KO) just reported its full-year 2025 results on Feb. 10, and the numbers reinforced exactly why this company has increased its dividend for 63 consecutive years, making it a Dividend King. (Dividend Kings are companies that have increased their cash dividend every single year for at least 50 consecutive years.) Organic revenue grew 5% for the year.

But what excites me most is the outlook for 2026. CEO James Quincey laid it out clearly: 4% to 5% organic revenue growth, 5% to 6% comparable currency-neutral earnings-per-share (EPS) growth, and approximately $12.2 billion in projected free cash flow.

That's a cash machine firing on all cylinders.​ With pricing power, global distribution that no competitor can match, and a brand portfolio that spans every beverage occasion imaginable, Coca-Cola is the definition of a compounding machine for patient investors.

3. Procter & Gamble

Procter & Gamble (NYSE: PG) isn't the sexiest stock on Wall Street, and that's precisely why I recommend it. This is a company that sells products people use every single day, like laundry detergent, toothpaste, diapers, razors, and it does so across 180 countries.

In its Q2 fiscal 2026 earnings released Jan. 22, net sales totaled $22.2 billion, with seven of 10 product categories posting organic sales growth.​ On top of this, the company is in the middle of a two-year restructuring program designed to increase productivity and sales per head, without requiring future waves of heavy investment once complete.

Five-out-of-seven regions grew organic sales in the quarter, with Latin America leading at 8% and Europe up 6%. Productivity savings contributed 270 basis points to results. And the company is returning enormous capital to shareholders, roughly $15 billion in fiscal 2026 through dividends and share repurchases combined.

The beauty of owning P&G stock over 20 years is the compounding of small advantages. Superior products, stronger brands, relentless cost discipline, and a dividend that has consistently grown annually for over six decades, making it another Dividend King.

In a world full of uncertainty, that kind of international consistency is priceless.

The common thread with these three companies

All three of these companies share something every long-term investor should treasure: durability. Costco's membership moat, Coca-Cola's branding, and P&G's dominance in daily use products give each a structural advantage that doesn't erode over time. If anything, it deepens over time.

Buy them, hold them, and let 20 years of compounding do the heavy lifting.
