BofA Merrill Lynch Survey Ranks AI Stock Bubble as Top Tail Risk Again

The BofA Merrill Lynch fund manager survey is a key gauge of global asset allocation and market consensus. A “tail risk” is an event with a low probability but potentially severe consequences. Concerns about a bubble remain at the top of the list after a sharp rise in AI stock valuations, echoing the JPMorgan CEO’s warning that current market conditions resemble the run-up to the 2008 financial crisis.

BofA Merrill Lynch’s February survey showed fund manager optimism rising to a six-year high, with more than half expecting the global economy to achieve a “no landing” scenario in which growth continues and recession is avoided. However, an “AI stock bubble” again ranked as the biggest tail risk. Allocations to technology stocks have declined, while investors have also become less enthusiastic about U.S. equities.

BofA Merrill Lynch Fund Manager Survey Flags AI Stock Bubble and Cloud Spending as Key Global Market Risks2026-03-20 · 1 reports · similarity 0.88

The BofA Merrill Lynch Fund Manager Survey is an important gauge of global institutional investors’ asset allocation and risk appetite. As AI stock valuations and investment in cloud infrastructure rise rapidly, markets are increasingly focused on risks involving returns on capital expenditure, corporate credit and excessive concentration in semiconductor holdings.

The latest March survey showed that the fund manager sentiment index fell to a six-month low amid geopolitical tensions and an uncertain economic outlook. An AI stock bubble and capital spending by AI cloud providers were cited as major tail and credit risks, while semiconductors remained the most crowded trade. The report did not disclose specific amounts or the survey date.
