Investors are facing a challenging landscape marked by concerns over a potential artificial intelligence (AI) bubble, rising global debt, and escalating geopolitical tensions. Amid this uncertainty, experts recommend strategies aimed at preserving and growing wealth through diversification and long-term investment.

Healthcare is highlighted as a resilient sector due to the consistent demand for medical care, pharmaceuticals, diagnostics, and devices regardless of economic conditions. Trevor M Polischuk, portfolio manager at Worldwide Healthcare Trust, points to companies such as Abbvie, known for immunology treatments; Gilead Sciences, a leader in HIV therapies; and Merck, which is noted not only for its current cancer drugs but also for its pipeline of upcoming therapies. The Polar Capital Global Healthcare fund focuses on broad exposure within the sector, holding significant positions in firms like Abbott Laboratories, a specialist in medical technologies.

The technology sector, however, has seen significant declines. Following its peak on October 6, around £3 trillion has been shaved off the Nasdaq index’s value, with shares of Alphabet — the parent company of Google and a key member of the so-called "Magnificent Seven" tech giants — falling 13% in a single trading day and declining roughly one-third since May. Other tech stalwarts such as Amazon and Intel have also experienced sharp drops, leading some analysts to describe the current period as "tech carnage." Despite these setbacks, some experts suggest that the correction might present investment opportunities for those willing to withstand volatility.

David Coombs, head of multi-asset investments at Rathbones, advocates for adherence to two key investment principles: diversification and time in the market. By spreading investments across various asset classes, sectors, and regions, investors reduce the risk of simultaneous downturns. Moreover, maintaining investments during volatile periods rather than selling can help preserve capital and position funds to benefit from market recoveries.

Commodities are another area attracting investor interest given their role as a driver of inflation. Over the past year, oil prices have increased by 87%, while copper has gained 31%. Investors can gain exposure through tracker funds or direct stock investments in companies such as Freeport, a copper miner, and Rio Tinto, the largest global iron ore producer. Gold remains a traditional safe haven, though it does not generate income and has shown mixed performance, rising 82% over three years but declining 8% in the past year. Greg Eckel of Canadian General Investment highlights Franco-Nevada, a company that finances mining operations in exchange for revenue shares and offers a history of steady dividend growth.

Utilities are seen as stable investments due to their essential nature and often monopolistic characteristics, which allow companies to maintain a steady customer base and pass on rising costs. Coombs favors companies like Wisconsin Energy in the U.S., and National Grid and SSE in the U.K. Waste Management, a U.S. firm specializing in waste collection, is also among his recommendations. Juliet Schooling Latter, research director at FundCalibre, points to the Regnan Sustainable Water And Waste Fund, which invests in utilities such as United Utilities, Severn Trent, and Veolia. These firms benefit from enduring trends including urbanization, infrastructure aging, resource efficiency, and regulatory tightening, and are generally less vulnerable to geopolitical risk.

Finally, “modern” utilities—technology companies providing critical everyday digital services like Microsoft, Alphabet, and Amazon—are considered another avenue for investors seeking exposure to essential services that have entrenched consumer demand.

Overall, experts emphasize the importance of building a diversified portfolio balanced across sectors and geographies, coupled with a patient, long-term approach to weather current market volatility and safeguard financial growth.
