The Motley Fool is highlighting five stocks for long-term investors seeking diversified holdings in today’s richly priced market. Motley Fool co-founder and CEO Tom Gardner recently shared his picks spanning the risk spectrum: Cisco Systems, MSCI, and Kingstone Companies as cautious positions; Marvell Technology as moderate; and BillionToOne as an aggressive choice.
Gardner argues that most investors should own at least 50 stocks to navigate the disruption AI is bringing across every industry. He points to legendary investor Peter Lynch, who held more than 500 companies at Fidelity Magellan while delivering 29% annualized returns for over a decade, as evidence that broad diversification doesn’t prevent market-beating performance.
The Motley Fool’s track record supports the long-term approach. As of August 25, 2026, the Stock Advisor service has delivered +958% in cumulative returns since inception compared to the S&P 500’s +212%, according to the company’s official figures. The service launched its recommendations in February 2002 and has maintained this performance advantage through multiple market cycles.
The five stocks Gardner highlighted reflect his market outlook. Cisco Systems, the networking backbone that powered the internet’s growth, now provides equipment connecting data centers and runs a growing security business following its Splunk acquisition. It generates $13 billion in free cash flow annually with double-digit returns on assets. MSCI provides global benchmarks for institutional investors and runs recurring subscription revenue exceeding $1 billion in annual free cash flow.
Kingstone Companies, a small homeowners insurance provider, has undergone a dramatic turnaround under CEO Meryl Golden, rising from below $1 per share to around $15. The company now operates an 88% combined ratio, meaning it earns a 12% profit margin on its insurance contracts while expanding from New York into California, where many insurers are retreating from wildfire risk.
Marvell Technology provides the chips that move data between servers and data centers—Gardner describes them as “highways and tunnels” complementing Nvidia’s GPU engines. The company is expected to generate $6 billion in free cash flow within a couple of years. BillionToOne, the aggressive pick, specializes in advanced genetic testing for prenatal and oncology applications, searching for disease signals among billions of DNA base pairs.
Gardner emphasizes that in a richly priced market, caution is warranted. When large IPOs come public, he notes, those are “some of the best-informed businesses in history choosing this moment to sell equity to the public”—a signal that valuations are elevated. Three of his five recommendations carry a cautious risk classification, one is moderate, and only one is aggressive, reflecting this defensive posture.
The philosophy underpinning these picks reflects decades of Motley Fool practice. The company does not compete on day trading or short-term predictions; instead, it looks five, ten, and twenty years ahead. Gardner cites Nvidia as an example: the company’s Rule Breakers team first recommended it in 2005 at what is now $0.16 per share. The stock has risen 1,300 times in value since then and was never sold by long-term holders, allowing some members to turn $5,000 into $6 million.
The Motley Fool’s core investing strategy centers on buying quality companies and holding them through market volatility. The service recommends building portfolios of 25 or more stocks, holding them for five years or longer, and investing new money regularly while letting winners run. This approach has resonated with tens of millions of investors worldwide seeking to build long-term wealth without the complexity of frequent trading or market timing.
