Early stages of a bull market are often met with investor negativity and equity sell-offs. This pessimism is a typical part of the behavioral cycle that precedes later-stage optimism and the euphoria which ultimately marks the market's peak. It is a sign that the cycle is not yet over.

During periods of intense market euphoria, investors with experience of past downturns are at a disadvantage. Their knowledge of how bubbles burst makes them cautious, causing them to underperform those who have only seen markets rebound, reinforcing a dangerous cycle of overconfidence.
Despite a massive tech stock run-up, key sentiment indicators and surveys of major asset allocators show caution, not the extreme bullishness seen in bubbles like the dot-com era. This suggests the market may not be at its absolute peak yet.
A true market bubble isn't defined by high valuations but by collective psychology. The most dangerous bubbles form when skepticism disappears and everyone believes prices will rise indefinitely. Constant debate about a bubble indicates the market hasn't reached that state of universal conviction.
The primary driver of market fluctuations is the dramatic shift in attitudes toward risk. In good times, investors become risk-tolerant and chase gains ('Risk is my friend'). In bad times, risk aversion dominates ('Get me out at any price'). This emotional pendulum causes security prices to fluctuate far more than their underlying intrinsic values.
Widespread public debate about whether a market is in a bubble is evidence that it is not. A true financial bubble requires capitulation, where nearly everyone believes the high valuations are justified and the skepticism disappears. As long as there are many vocal doubters, the market has not reached the euphoric peak that precedes a crash.
The primary indicator of a healthy bull market is when technical breakouts are sustained and lead to higher prices. If breakouts consistently fail and your positions stagnate, it's a red flag that the underlying trend is weakening, even if indices are high.
Current market bullishness is at levels seen only a few times in the past decade. Two of those instances led to corrections within three months. This euphoria, combined with low volatility and high leverage, makes the market vulnerable to even minor negative news.
Historical bubbles, like the dot-com era, occur only when everyone capitulates and believes prices can only go up. According to Ben Horowitz, the constant debate and anxiety about a potential AI bubble is paradoxically the strongest evidence that the market has not yet reached the required state of collective delusion.
Contrary to intuition, widespread fear and discussion of a market bubble often precede a final, insane surge upward. The real crash tends to happen later, when the consensus shifts to believing in a 'new economic model.' This highlights a key psychological dynamic of market cycles where peak anxiety doesn't signal an immediate top.
Despite the start of a new bull market, current 'frothy' conditions make a significant pullback likely. This should be viewed not as a threat, but as a normal occurrence and a buying opportunity. Near-term catalysts include escalating China trade tensions, stress in funding markets from quantitative tightening, and peaking earnings revisions.
