A basic characteristic of bubbles is the suspension of disbelief by most participants when the speculative price surge is occurring: It's only in retrospect, after the bubble has burst, that they're recognized (to many an investor's chagrin). Nevertheless, some economists have identified five stages of a bubble—a pattern to its rise and fall—that could prevent the unwary from getting caught in its deceptive clutches.
- Financial bubbles are deceptive and unpredictable, but understanding the five stages they characteristically go through can help investors prepare for them.
- The five steps in the lifecycle of a bubble are displacement, boom, euphoria, profit-taking, and panic.
What Is a Bubble?
The term "bubble," in a financial context, generally refers to a situation where the price for something—an individual stock, a financial asset, or even an entire sector, market, or asset class—exceeds its fundamental value by a large margin. Because speculative demand, rather than intrinsic worth, fuels the inflated prices, the bubble eventually but inevitably pops, and massive sell-offs cause prices to decline, often quite dramatically. In most cases, in fact, a speculative bubble is followed by a spectacular crash in the securities in question.
The damage caused by the bursting of a bubble depends on the economic sector/s involved, and also whether the extent of participation is widespread or localized. For example, the bursting of the equity and real estate bubbles in Japan in 1989-1992 led to a prolonged period of stagnation for the Japanese economy—so long that the 1990s are referred to as the Lost Decade. In the U.S., the burst of the dotcom bubble in 2000 and the housing bubble in 2008 led to severe recessions.
5 Steps of a Bubble
Five Stages of a Bubble
Economist Hyman P. Minsky was one of the first to explain the development of financial instability and the relationship it has with the economy. in his pioneering book Stabilizing an Unstable Economy (1986), he identified five stages in a typical credit cycle, one of several recurrent economic cycles.
These stages also outline the basic pattern of a bubble.
A displacement occurs when investors get enamored by a new paradigm, such as an innovative new technology or interest rates that are historically low. A classic example of displacement is the decline in the federal funds rate from 6.5% in May 2000, to 1% in June 2003. Over this three-year period, the interest rate on 30-year fixed-rate mortgages fell by 2.5 percentage points to a historic low of 5.21%, sowing the seeds for the subsequent housing bubble.
Prices rise slowly at first, following a displacement, but then gain momentum as more and more participants enter the market, setting the stage for the boom phase. During this phase, the asset in question attracts widespread media coverage. Fear of missing out on what could be a once-in-a-lifetime opportunity spurs more speculation, drawing an increasing number of investors and traders into the fold.
During this phase, caution is thrown to the wind, as asset prices skyrocket. Valuations reach extreme levels during this phase as new valuation measures and metrics are touted to justify the relentless rise, and the "greater fool" theory—the idea that no matter how prices go, there will always be a market of buyers willing to pay more—plays out everywhere. For example, at the peak of the Japanese real estate bubble in 1989, land in Tokyo sold for as much as $139,000 per square foot or more than 350 times the value of Manhattan property. Similarly, at the height of the internet bubble in March 2000, the combined value of all technology stocks on the Nasdaq was higher than the GDP of most nations.
In this phase, the smart money—heeding the warning signs that the bubble is about at its bursting point—starts selling positions and taking profits. But estimating the exact time when a bubble is due to collapse can be a difficult exercise because, as economist John Maynard Keynes put it, "the markets can stay irrational longer than you can stay solvent." In August 2007, for example, French bank BNP Paribas halted withdrawals from three investment funds with substantial exposure to U.S. subprime mortgages because it could not value their holdings. While this development initially rattled financial markets, it was brushed aside over the next couple months, as global equity markets reached new highs. In retrospect, Paribas had the right idea, and this relatively minor event was indeed a warning sign of the turbulent times to come.
It only takes a relatively minor event to prick a bubble, but once it is pricked, the bubble cannot inflate again. In the panic stage, asset prices reverse course and descend as rapidly as they had ascended. Investors and speculators, faced with margin calls and plunging values of their holdings, now want to liquidate at any price. As supply overwhelms demand, asset prices slide sharply. One of the most vivid examples of global panic in financial markets occurred in October 2008, weeks after Lehman Brothers declared bankruptcy and Fannie Mae, Freddie Mac and AIG almost collapsed. The S&P 500 plunged almost 17% that month, its ninth-worst monthly performance. In that single month, global equity markets lost a staggering $9.3 trillion of 22% of their combined market capitalization.
Tulipmania describes the first major financial bubble, which took place in the 17th-century Holland: Prices for tulips soared beyond reason, then fell as fast as the flower's petals.
Example of a Stock Bubble: eToys
The internet bubble around the turn of the 21st century was an especially dramatic one. Numerous internet-related companies made their public debut in spectacular fashion in the late1990s before disappearing into oblivion by 2002. The story of eToys illustrates how the stages of a stock bubble typically play out.
A Rosy Start
In May 1999, with the internet revolution in full swing, eToys had a very successful initial public offering, where shares at $20 each escalated to $78 on their first trading day. The company was less than three years old at that point and had grown sales to $30 million for the year ended March 31, 1999, from $0.7 million in the preceding year. Investors were very enthusiastic about the stock's prospects, with the general thinking being that most toy buyers would buy toys online rather than at retail stores such as Toys "R" Us. This was the displacement phase of the bubble.
As the 8.3 million shares soared in its first day of trading on the Nasdaq, giving it a market value of $6.5 billion, investors were eager to buy the stock. While eToys had posted a net loss of $28.6 million on revenues of $30 million in its most recent fiscal year, investors were expecting the financial situation of the firm to take a turn for the best. By the time markets closed on May 20, eToys sported a price/sales valuation that was largely exceeding that of rival Toys "R" Us, which had a stronger balance sheet. This marked the boom and euphoria stages of the bubble.
Shortly afterward, eToys fell 9% on concern that potential sales by company insiders could drag down the stock price, following the expiry of lockup agreements that placed restrictions on insider sales. Trading volume was exceptionally heavy that day, at nine times the three-month daily average. The day's drop marked a 40% decline in the stock, from its record high of $86, identifying this as the profit-taking phase of the bubble.
Decline and Fall
By March 2000, the panic stage had arrrived: eToys had tumbled 81% from its October peak to about $16 on concerns about its spending. The company was spending an extraordinary $2.27 on advertising costs for every dollar of revenue generated. Although the investors were saying that this was the new economy, such a business model simply is not sustainable.
In July 2000, eToys reported its fiscal first-quarter loss widened to $59.5 million from $20.8 million a year earlier, even as sales tripled over this period to $24.9 million. It added 219,000 new customers during the quarter, but the company was not able to show bottom-line profits. By this time, with the ongoing correction in technology shares, the stock was trading around $5.
Towards the end of the year, with losses continuing to mount, eToys would not meet its fiscal third-quarter sales forecast and had just four months of cash left. The stock, which had already been caught up in the panic selling of internet-related stocks since March and was trading around at slightly over $1, fell 73% to 28 cents by February 2001. Since the company failed to retain a stable stock price of at least $1, it was delisted from the Nasdaq.
A month after it had reduced its workforce by 70%, eToys fired its remaining 300 workers and was forced to declare bankruptcy. By this time, eToys had lost $493 million over the previous three years and had $274 million in outstanding debt.
The Bottom Line
As Minsky and a number of other experts opine, speculative bubbles in some asset or the other are inevitable in a free-market economy. However, becoming familiar with the steps involved in bubble formation may help you to spot the next one and avoid becoming an unwitting participant in it.
