When an asset sees a massive price surge, it's effectively a "price compression" that pulls years of expected returns into a short period. This raises the probability of future volatility or stagnant performance, as the future gains have already been realized.

A long bull market can produce a generation of venture capitalists who have never experienced a downturn. This lack of cyclical perspective leads to flawed investment heuristics, such as ignoring valuation discipline, which are then painfully corrected when the market inevitably turns.
Massive investment requires issuing assets (bonds, equity), creating supply pressure that pushes prices down. The resulting spending stimulates the real economy, but this happens with a lag. Investors are in the painful phase where supply is high but growth benefits haven't yet materialized.
Veteran investor Jim Schaefer notes a recurring pattern before recessions: a massive, euphoric movement of capital into a specific area (e.g., telecom in 2001, mortgages in 2008). This over-investment inevitably creates systemic problems. Investors should be wary of any asset class currently experiencing such a large-scale influx.
The current AI boom isn't just another tech bubble; it's a "bubble with bigger variance." The potential for massive upswings is matched by the risk of equally significant downswings. Investors and founders must have an unusually high tolerance for risk and volatility to succeed.
Bubbles are created when assets like startup equity are valued astronomically, creating immense perceived wealth. However, this "wealth" is not money until it's sold. A crash occurs when events force mass liquidation, revealing a scarcity of actual money to buy the assets.
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.
Bitcoin's 27% plunge, far exceeding the stock market's dip, shows how high-beta assets react disproportionately to macro uncertainty. When the central bank signals a slowdown due to a "foggy" outlook, investors flee to safety, punishing the riskiest assets the most.
The S&P 500's high concentration in 10 stocks is historically rare, seen only during the 'Nifty Fifty' and dot-com bubbles. In both prior cases, investors who bought at the peak waited 15 years to break even, highlighting the significant 'dead capital' risk in today's market.
Unlike the 2008 crisis, which was concentrated in housing and banking, today's risk is an 'everything bubble.' A decade of cheap money has simultaneously inflated stocks, real estate, crypto, and even collectibles, meaning a collapse would be far broader and more contagious.
When a small, speculative investment like crypto appreciates massively, it can unbalance an entire portfolio by becoming an oversized allocation. This 'good problem' forces investors to systematically sell the high-performing asset to manage risk, even as it continues to grow.
