Insights from Robert Shiller
As we listen to the financial channels during the day, it seems that every hour there is some interview with a pundit around the “AI bubble”. Having been through 2000 and 2009, we know one individual that is, in our humble opinion the Greatest of All Time when it comes to identifying the signs of a potential “bubble”. Tom has started a new book “ How stories go viral and drive major economic events”. Early in the book he mentions 12 signals that you may be entering bubble territory, so we went to Google Gemini to give us a summary of these signals. We are happy to discuss any, or all, of the below.
While a definitive, static "twelve signs" checklist isn't attributed to Robert Shiller, his work, particularly the seminal book Irrational Exuberance, outlines a comprehensive list of psychological and structural factors that define and fuel speculative asset bubbles. The following is a synthesis of the key behavioral and systemic indicators Shiller identified through his analysis of market history.
The psychological drivers
1. "New Era" theories: A bubble is often accompanied by a compelling narrative that justifies unprecedented price increases, claiming that traditional valuation measures are outdated because the economy or a particular industry has entered a "new era".
2. Psychological contagion: Investor enthusiasm, spurred by news of rising prices, spreads through social and psychological feedback loops. This often includes herd behavior, where individuals invest because others are doing so, regardless of their own analysis.
3. Envy and gambler's excitement: Stories of people making easy money in the market trigger feelings of envy and fear of missing out (FOMO) among those on the sidelines. This draws in an ever-wider class of inexperienced investors.
4. Overconfidence and overvaluation: Investor optimism becomes excessive, leading to the belief that recent price gains will continue indefinitely. This pushes asset prices to levels far beyond their intrinsic, fundamental value.
5. Media frenzy and amplification: The media plays a significant role in broadcasting stories of success, which helps spread the narrative and intensify public excitement.
The structural and economic indicators
6. Rapid price increases: A bubble is most obviously signaled by a sharp and significant increase in the price of an asset over a relatively short period.
7. Elevated trading volume: High speculation drives trading volumes to unsustainable levels as investors seek quick gains, rather than holding assets for their long-term value.
8. Decline in lending standards: The increase in speculative demand is often fueled by cheap and easy credit. Lenders lower their standards to accommodate a wider pool of buyers, as seen during the 2000s housing bubble with practices like "NINJA" loans (no income, no job, or assets).
9. Increased leverage: Investors use high levels of margin debt and other forms of leverage to increase their purchasing power and magnify returns. This makes the entire system more vulnerable to a crash.
10. Tortured rationalizations: As prices become increasingly detached from fundamentals, investors develop convoluted and flimsy arguments to justify the continued rise.
11. Focus on capital gains: The narrative shifts from the asset's underlying value—like dividends or rent—to the expectation of future capital gains. Investors begin to see assets purely as speculative objects to be resold for a higher price.
12. Increased inequality: Historically, periods of extreme asset bubbles have coincided with a growing wealth gap. As a bull market progresses, a disproportionate amount of wealth flows to those at the top.
