Investors should be wary of waiting for an ideal market environment before putting surplus cash to work, UBS said in a strategy note, recommending that excess liquidity be allocated into diversified portfolios even as major equity indexes trade close to record highs.
The bank acknowledged several credible reasons for restraint - geopolitical frictions, inflationary pressures, uncertainty about interest-rate paths, lofty valuations and open questions about how durable artificial intelligence-related spending will be. But UBS warned that sitting on cash until those risks fade risks leaving capital underinvested over the long run.
UBS examined three decades of data and found that when U.S. stocks hit fresh highs, the year that followed often produced returns that were comparable to or better than prior performance. The bank also noted that market responses to geopolitical incidents have typically proved transient, with investor focus reverting to economic metrics and corporate results.
On fundamentals, UBS projects global corporate earnings to expand by roughly 21% in 2026. The bank said this growth should be supported by resilient economic activity and by profit gains that extend beyond a narrow set of technology companies.
While advocating for deployment of surplus cash, UBS stressed that cash remains appropriate for short-term needs like upcoming spending, tax bills and other planned commitments. The bank pointed out that with deposit rates falling and inflation present, large idle cash balances can lose purchasing power over time and become less effective at meeting long-term objectives.
UBS suggested a pragmatic approach: lock in current bond yields for capital required over shorter horizons, and then either invest remaining balances immediately or in stages. A phased approach can help reduce the behavioral risk associated with buying near record highs, though the bank was clear that such a tactic does not guarantee superior returns.
Diversification was a key practical recommendation. UBS highlighted that many individual investors run concentrated portfolios - nearly 40% of self-directed equity investors on UBS’s platform hold more than half of their equity allocation in ten or fewer stocks. To mitigate concentration risk, the bank recommended broadening exposure across equities, quality fixed income, infrastructure and selected alternative assets.
UBS identified several long-term investment themes investors may consider: artificial intelligence, power and resources, longevity, China, Japan and emerging markets. In the fixed-income sleeve, the bank pointed to investment-grade credit, high-yield debt and emerging-market bonds as potential income sources, while noting that shorter-maturity bonds can offer some protection should equity volatility pick up.
Implications for investors
- Surplus cash should be evaluated against short-term liabilities and long-term goals; excess balances may need redeployment to avoid erosion from inflation and lower deposit rates.
- Careful diversification across asset classes and geographies can address concentration risks present in many individual equity portfolios.
- Using bonds to lock yields for near-term capital needs while deploying remaining cash either immediately or gradually is a practical way to balance income and market-timing concerns.
