Stock Bulls Have a Worryingly Long List of 2026 Risks to Ponder

Inflation and Rates

Article content

Markets are still anchored to the assumption that inflation is cooling and policy rates will drift lower. But inflation may not play ball, with price pressures potentially flowing from heavy AI spending or lingering tariff effects. The upshot would be the Fed keeping rates higher for longer — or even tightening financial conditions. Bond yields would likely rise, pushing up equity discount rates and challenging investors’ tolerance for lofty valuations.

Rate volatility itself is a risk: abrupt repricing in the front end of the curve tends to spill over into equities, particularly among growth stocks. For investors positioned for a benign rates backdrop, the asymmetry is clear — surprises skew negative.

Geopolitics and Trade

Article content

Geopolitical risk lurks as a latent but potent threat to equities. Tensions between the US and China, conflicts that ripple through energy markets, or disruptions to critical supply chains — including semiconductors and rare-earth minerals — could trigger abrupt risk-off moves.

Trade policy is another wildcard, particularly if tariffs return to the political spotlight. For markets, the issue is less about forecasting outcomes than pricing uncertainty. History shows that geopolitical shocks often lead to spikes in volatility, dollar strength and equity drawdowns, even if the long-term economic impact proves manageable. In a market priced for stability, such events carry an outsized impact.

Macroeconomic Slowdown

The consensus is that the US economy will prove robust, while hopes for Europe revolve around a spending spree among governments. But any cracks in this narrative will be closely watched.

Questions around how consumers are coping with cost-of-living pressures and how bank balance sheets are handling credit risk will be top of mind. A forced slowdown in fiscal spending or dips in corporate hiring could quickly translate into weaker earnings, particularly outside megacap tech companies. With expectations for earnings growth still optimistic, any downside revisions could trigger broader de-risking.

“One thing that keeps me up a little bit at night is the macro softening,” said Helen Jewell, international chief investment officer of fundamental equities at BlackRock Inc. “My nervousness is that actually you end up in a K-shaped economy and its knock-on effect of the consumer,” she said.

The Sideshows

Deteriorating liquidity during drawdowns, crowded trading as well as increased flows from leveraged ETFs, systematic investors and passive strategies may not be risk events in themselves, but they make stocks more reactive under stress.

The pace at which volatility spikes have faded have helped markets to overcome episodes of stress, but this poses a challenge for hedging and market timing. It can potentially encourage investors to execute faster, sparking episodes of sell first, ask questions later.

Buybacks have proved a major pillar of market support, but might vanish should the economy falter. Add to the list of concerns increasing sensitivity in markets to government financing and public deficits. The same goes for regulatory and legal shocks, which are worth keeping in mind for 2026, as AI remains arguably lacking in clear rules.

And finally there is consensus risk. When most investors agree on why markets are rising — AI productivity, the economic outlook and rate cuts — the risk isn’t being wrong eventually, but being wrong together. The vulnerability may lie in the market structure’s itself — where positioning, liquidity and sentiment interact in ways that turn small catalysts into large moves.
