A key argument for market bulls is that the Federal Reserve is cutting interest rates while a potential AI bubble is inflating. This is a stark contrast to the dot-com era, when the Fed hiked by 175 basis points, making historical analogies difficult and creating a unique tailwind for equities.
A market enters a bubble when its price, in real terms, exceeds its long-term trend by two standard deviations. Historically, this signals a period of further gains, but these "in-bubble" profits are almost always given back in the subsequent crash, making it a predictable trap.
The recent gold rally was disconnected from institutional indicators like a falling dollar or rising break-evens. Instead, it was propelled by retail investors' fears of currency debasement, leading to meme-like behavior such as people lining up to get physical gold from vaults.
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.
For traders, the defining characteristic of an emerging market isn't GDP but how its sovereign bonds behave during risk-off events. If bonds sell off alongside equities when volatility rises, it's an EM. If they rally as a safe haven, it's a developed market, regardless of economic metrics.
A macro strategist recalls dot-com era pitches justifying valuations with absurd scenarios like pets needing cell phones or a company's tech being understood by only three people. This level of extreme mania highlights a key difference from today's market, suggesting current hype levels are not unprecedented.
Calling a market top is a technical exercise, as fundamentals lag significantly. A reliable sell signal emerges when the market's leadership narrows to a few "generals." When a critical number of these leaders (e.g., three of the top seven) fall below their 200-day moving average, the rally is likely over.
