This Citi framework is interesting because it does not argue that a bear market is imminent. Rather, it argues that many of the ingredients historically present at major market peaks are already in place. What stands out immediately is valuation. US equities are trading at 28x trailing earnings, 22x forward earnings, and a CAPE ratio of 46. Those levels are comparable to, and in some cases exceed, conditions seen at prior major peaks. The US equity risk premium has compressed to just 2.5%, meaning investors are accepting historically low compensation for taking equity risk. At the same time, sentiment remains elevated. Analyst bullishness is above average, fund flows remain positive, and Citi’s panic/euphoria indicator sits firmly in euphoric territory. Historically, major bear markets rarely begin when investors are fearful. They usually begin when optimism is widespread and risk is perceived to be low. Corporate behavior also resembles late-cycle conditions. US capex growth is projected at 33% in 2026, far above historical norms and one of the highest readings in the table. Importantly, much of this spending is concentrated in AI infrastructure, data centers, semiconductors, and power systems. Investors view this as productive investment today, but history shows that periods of aggressive capital spending can sometimes lead to overcapacity later. The most important counterargument is profitability. Unlike previous market peaks, corporate fundamentals remain exceptionally strong. US ROE sits at 21%, earnings are 34% above previous peaks, leverage is relatively contained, and credit spreads remain tight. In other words, this is not a market being driven purely by speculation. Earnings are genuinely strong. That is why this cycle looks different from 2000. During the dot-com bubble, valuations exploded while profitability remained weak. Today, the largest technology companies are generating enormous cash flows, dominant market positions, and some of the highest returns on capital ever seen. The chart’s “sell signal” count reflects this tension. The US currently registers 11.5 out of 18 warning signals, higher than most periods but still below the extremes seen in 2000 and 2007. In other words, conditions look stretched, but not yet at the levels historically associated with the start of major secular bear markets. The bigger question is what happens if earnings continue surprising to the upside. Markets ultimately care less about valuation in isolation and more about the relationship between valuation and future earnings growth. If AI-driven productivity gains materially accelerate earnings over the next several years, today’s multiples may eventually look less extreme than they appear. This is why the current market is so difficult to handicap. The bears see valuations, euphoric sentiment, and compressed risk premia. The bulls see the strongest earnings cycle in decades, unprecedented AI investment, and some of the highest-quality corporate balance sheets ever observed. Our interpretation is that this chart is not necessarily signaling an imminent bear market. Instead, it suggests future returns are becoming increasingly dependent on execution. When valuations are already elevated, companies must continue delivering extraordinary earnings growth to justify current prices. The margin for disappointment becomes much smaller. That is particularly relevant today because much of the market’s optimism rests on AI. If AI delivers the productivity and earnings acceleration investors expect, valuations can remain elevated for years. If those expectations prove too optimistic, the compression in multiples could be painful even if earnings continue growing.
