Our Highest Rated Mega-Cap Stocks

Featured Companies

Mega-cap companies (those with a market cap above $200B) are the economic titans that define entire industries and shape global commerce. These are the household names with near-monopolistic positions, global ecosystems, and the financial resources to acquire competitors, create new markets, or weather any storm. When mega-caps move, entire sectors follow.

The investment opportunity here isn't about discovering hidden gems, it's about identifying which giants will expand their dominance and compound wealth over decades. At this scale, execution matters more than innovation, and management quality can create or destroy hundreds of billions in value. The best mega-caps operate multiple cash-generating businesses while simultaneously investing in future growth platforms.

Below are the highest rated mega-cap stocks in our research portfolio.

UnitedHealth Group Incorporated UNH

UnitedHealth Group looks like a classic compounder hiding in plain sight: gigantic yet still growing, with a moat built from regulatory licences, data scale and cost advantages few can match. Free cash gushes in, debt is moderate and management historically reinvests capital at mid-teens returns. Headline risks—from Medicare fraud probes to PBM reform—keep the valuation in check, giving patient investors a shot at buying a durable market leader below its long-run fair value.

Berkshire Hathaway Inc. BRK-B

Berkshire is still the financial Fort Knox it was in Buffett’s hey-day: monopoly-like rail & utility assets, oceans of cheap insurance float earning fat T-Bill yields and a war chest big enough to buy half of Wall Street if things get ugly. Legal fires smoulder in Oregon and climate critics howl, but the cash keeps gushing. With the stock priced at a teenager-level P/E and a one-third discount to our base-case value, long-term investors get both resilience and upside without needing a crystal ball.
