TIP 065 : Yale Professor, Robert Shiller's Book, Irrational Exuberance (Investing Podcast)

Episode Summary

Executive Summary: The episode combines a macro market discussion with a book review of Robert Shiller’s Irrational Exuberance. Preston and Stig argue that China, Europe, Japan, and the Fed are all creating distorted conditions through intervention, easing, and policy shifts, while valuation metrics like the Shiller P/E and corporate margins suggest U.S. markets are expensive and vulnerable. They conclude by applying the book’s warnings to today’s speculative environment and advising DIY investing over automated ETF wrappers for simple passive portfolios.

Main Topics: Global macro conditions and central bank policy (Priority: 5/5): The hosts discuss China, Europe, Japan, and the U.S. Fed, emphasizing currency shifts, negative rates, QE, and the uncertainty created by heavy intervention. China’s market recovery and RMB inclusion in the SDR basket (Priority: 4/5): They note China’s stock market rebound from the summer selloff and discuss the IMF adding the RMB to the SDR basket as a sign of China’s rising global financial role. Fed rate decision and implications for markets (Priority: 5/5): Preston and Stig speculate the Fed will raise rates by 25 bps and discuss likely effects: stronger dollar, pressure on U.S. firms, higher stress on dollar debt, and possible commodity weakness. Review of Irrational Exuberance and valuation discipline (Priority: 5/5): The discussion centers on Shiller’s thesis that low rates and investor psychology inflate asset prices, and that high valuations can imply poor long-term returns. The internet, the 'new economy,' and bubble psychology (Priority: 4/5): They compare the dot-com era to 1929, arguing that new technology narratives often justify excessive multiples without changing basic valuation realities. Media amplification and feedback loops (Priority: 3/5): Shiller’s point that media often retrofits stories to market moves is highlighted as a mechanism that intensifies investor sentiment and market hysteria. Automated investing platforms and passive ETF management (Priority: 3/5): A listener question prompts a critique of Betterment/Wealthfront-style services, with the hosts arguing that low-cost ETF portfolios can often be built directly without paying an intermediary.

Key Arguments: China may have stabilized short term, but government intervention and opaque accounting make it unattractive to invest in now. The RMB’s inclusion in the IMF’s SDR basket signals China’s growing global financial importance, even if its currency remains heavily managed. Negative ECB deposit rates and extended QE may support banks but do not reliably translate into real economic growth or broad consumer spending. If the Fed raises rates, the dollar likely strengthens, which could hurt U.S. exporters, compress margins, and stress emerging markets with dollar-denominated debt. Shiller’s core warning is that high market valuations can produce very low long-term returns even if prices continue rising for a while. The dot-com era was driven by a narrative of a 'new economy,' but widespread adoption of new technology does not automatically justify extreme multiples. Journalists often explain market moves after the fact, amplifying sentiment rather than providing causal insight. High corporate margins can support higher valuations, but a sustained margin decline often precedes recessions. Passive investing via ETFs can be done directly at very low cost; hiring a robo-advisor to assemble mostly index funds may add little value. Shiller’s market-timing warnings were broadly right in the 2000 era, but his writing style is dense and dry compared with more entertaining finance books.

Data Points: China market level (August): about 2,900 - Referenced as the level before the summer selloff recovery. China market level (Dec. 7, 2015): about 3,500 - Used to describe a rebound of roughly 10%+ from the August low. RMB weight in SDR basket: just short of 11% - IMF composition after adding the Chinese yuan/RMB. U.S. dollar weight in SDR basket: 42% - Comparison point for the IMF currency basket. Euro weight in SDR basket: 31% - Comparison point for the IMF currency basket. ECB deposit rate: negative and more negative than the prior week - Illustrates Europe’s aggressive easing stance. ECB QE purchase pace: 60 billion euros per month - Monthly bond-buying under the expanded QE program. ECB QE end date after extension: March 2017 - Program extended by six months from the prior expected end. Japan market level (August): 20.5K - Japanese index level before the later pullback. Japan market level (Dec. 7, 2015): 19.6K - Represents about a 5% decline from August. Japan recession count: 4th recession in 5 years - Mentioned as of Nov. 16, reinforcing concern about the economy. Expected Fed move: 25 basis points - Preston’s forecast for the December Fed meeting. Hussman market return forecast: 1% annual return over the next 12 years - Based on current valuation levels and cited as a modern analogue to Schiller’s warning. Amazon P/E multiple: close to 1,000 - Used to illustrate extreme valuation and low implied earnings yield. Normal stock multiple referenced: 15x earnings - Explained as paying $15 for $1 of annual earnings. Market margin peak: around 12% - Referenced as the recent peak in corporate profit margins. Earlier margin range: around 6%-7% - Suggested margin levels from the 1980s. Margin decline signal: 60 basis points - Described as a recurring recession warning threshold. Margin warning lead time: 15 to 18 months - Approximate lag between margin peak/decline and recession onset. Betterment/Vanguard correlation: 95% - Used to argue that a robo-advisor portfolio largely mirrors a market index. Potential market return after 2000-style valuation: near zero over 10 years - Shiller’s historical call, later framed as correct in hindsight.

Pivotal Quotes: "Clearly, sustained low inflation implies less uncertainty about the future." — Alan Greenspan (quoted by Preston): Used to introduce Shiller’s title concept and explain how falling rates can lift asset prices. "How do we know when irrational exuberance has unduly escalated asset values" — Alan Greenspan (quoted by Preston): The defining phrase behind the book’s title and central warning about bubbles. "I see the stock market as being the end result of a well-run economy, not the other way around." — Stig: Stig’s critique of the idea that the stock market should drive policy or economic growth.

Implications: Listeners are encouraged to focus on valuation, margins, and policy distortion rather than headlines. The episode warns that easy money can inflate bubbles, while simple low-cost indexing may be preferable to paying for needless automation.
