The Four Phases Of A Bubble

Interesting chart showing the four psychological phases of a bubble via Prof Jean-Paul Rodrigue.

To become a good investor, you have to be very prescient. If you can be in the “Stealth” or “Awareness” phases above then you are leagues ahead of everyone else. Of course the tricky part is that being too early is often the same as being too late.

But to become a great investor, you also have to master the psychology of bubbles and business cycles. So it’s important for investors to study these four phases and view each of their investments through this lens.

Here’s how Prof. Rodrique describes the four phases:

Bubbles (financial manias) unfold in several stages, an observation which backed up by 500 years of economic history. Each mania is obviously different, but there are always similarities; simplistically four phases can be identified:

Stealth. Those who understand the new fundamentals realize an emerging opportunity for substantial future appreciation, but at a risk since their assumptions are so far unproven. So the “smart money” gets invested in the asset class, often quietly and cautiously. This category of investor tends to have better access to information and a higher capacity to understand the wider economic context that would trigger asset inflation. Prices gradually increase, but often completely unnoticed by the general population. Larger and larger positions are established as the smart money start to better understand that the fundamentals are well grounded and that this asset class is likely to experience significant future valuations.

Awareness. Many investors start to notice the momentum, bringing additional money in and pushing prices higher. There can be a short-lived sell off phase taking place as a few investors cash in their first profits (there could also be several sell off phases, each beginning at an higher level than the previous one). The smart money takes this opportunity to reinforce its existing positions. In the later stages of this phase the media starts to notice with positive reports about how this new boom benefits the economy by “creating” wealth; those getting in becoming increasingly “unsophisticated”.

Mania. Everyone is noticing that prices are going up and the public jumps in for this “investment opportunity of a lifetime”. The expectations about future appreciation becomes a “no brainer” and a linear inference mentality sets in; future prices are an extrapolation of past price appreciation, which of course goes against any conventional wisdom. This phase is however not about logic, but a lot about psychology. Floods of money come in creating even greater expectations and pushing prices to stratospheric levels. The higher the price, the more investments pour in. Fairly unnoticed from the general public caught in this new frenzy, the smart money as well as many institutional investors are quietly pulling out and selling their assets. Unbiased opinion about the fundamentals becomes increasingly difficult to find as many players are heavily invested and have every interest to keep asset inflation going. The market gradually becomes more exuberant as “paper fortunes” are made from regular “investors” and greed sets in. Everyone tries to jump in and new intrants have absolutely no understanding of the market, its dynamic and fundamentals. Prices are simply bid up with all financial means possible, particularly leverage and debt. If the bubble is linked with lax sources of credit, then it will endure far longer than many observers would expect, therefore discrediting many rational assessments that the situation is unsustainable. At some point statements are made about entirely new fundamentals implying that a “permanent high plateau” has been reached to justify future price increases; the bubble is about to collapse.

Blow-off. A moment of epiphany (a trigger) arrives and everyone roughly at the same time realize that the situation has changed. Confidence and expectations encounter a paradigm shift, not without a phase of denial where many try to reassure the public that this is just a temporary setback. Some are fooled, but not for long. Many try to unload their assets, but takers are few; everyone is expecting further price declines. The house of cards collapses under its own weight and late comers (commonly the general public) are left holding depreciating assets while the smart money has pulled out a long time ago. Prices plummet at a rate much faster than the one that inflated the bubble. Many over-leveraged asset owners go bankrupt, triggering additional waves of sales. There is even the possibility that the valuation undershoots the long term mean, implying a significant buying opportunity. However, the general public at this point considers this sector as “the worst possible investment one can make”. This is the time when the smart money starts acquiring assets at low prices.

Bubbles can be very damaging, especially for those who arrived late with the hope of getting something for nothing. Even if they are inflationary events, the outcome of a bubble’s blow off is very deflationary as large quantities of capital vanish in the wave of bankruptcies and financial defaults they trigger. Historically, they tended to be far in-between, but between 1995 and 2008 three bubbles took place back-to-back; the stock market (deflated in 2000), real estate (deflated in 2006) and commodities (deflated in 2008).
