Bubble 

Market bubbles are a recurring phenomenon in financial history. For new investors, understanding what a bubble is, how it forms, and how to avoid being caught in one is vital to protecting your portfolio. This article explains everything you need to know about bubbles in the investment world using examples from the different markets. 

What is a Bubble? 

A bubble refers to a situation where the price of an asset, such as stocks, real estate, or commodities, rises sharply to levels that are much higher than its actual or intrinsic value. These inflated prices are usually driven by strong investor enthusiasm, speculation, and the belief that prices will continue to rise indefinitely. 

However, such growth is unsustainable. Eventually, when confidence fades or reality sets in, the bubble bursts. Prices collapse rapidly, often leaving investors with significant losses. 

Understanding Bubble 

Bubbles often occur when investors collectively ignore the actual value of an asset and focus instead on its rising price. As more people buy in, demand increases and prices rise further, creating a feedback loop. This phase is primarily driven by market sentiment rather than real performance. 

For example, in a stock market bubble, companies might not have strong earnings or sound financials, but their stock prices surge simply because everyone else is buying them. Investors often act out of fear of missing out (FOMO), and herd behaviour dominates rational thinking. 

When enough people start to realise that the price is unjustified, panic sets in. Selling accelerates, prices fall, and the bubble bursts. 

Types of Bubble 

Bubbles are not limited to the stock market—they can affect different kinds of assets. Common types include: 

a) Stock Market Bubble

Occurs when share prices are driven by speculation, not fundamentals. An example is the technology stocks of the late 1990s in the US, which achieved extreme valuations despite little profit or revenue to justify them. 

b) Real Estate Bubble

Happens when property prices climb far above their market value due to speculation and cheap borrowing. These bubbles are particularly dangerous because property is a long-term investment, and corrections can take years to recover. 

c) Credit Bubble

Occurs when there’s excessive lending, often with little regard for creditworthiness. A housing-related credit bubble in the US contributed significantly to the financial crisis of 2008. 

d) Commodity Bubble

Occurs when physical goods, such as oil, gold, or agricultural products, are bought and sold at inflated prices due to investor speculation rather than actual supply and demand. 

e) Cryptocurrency Bubble

A modern example is where digital currencies, with limited real-world utility or regulation, see dramatic price swings due to online hype and speculative buying. 

Stages of a Market Bubble: From Boom to Bust 

Bubbles typically go through five clear stages: 

1. Displacement

A new idea, innovation or trend captures investor attention. This might be a new technology, deregulation, or entry into a new market. 

2. Boom

Prices start to rise steadily. Positive news attracts more investors, leading to increased media coverage and wider interest. 

3. Euphoria

At this stage, caution is abandoned. Everyone wants a piece of the action. Prices skyrocket, and even weak or unprofitable assets are bought blindly. 

4. Profit-taking

Early investors begin to exit and take profits. Prices may stabilise temporarily, but market confidence begins to weaken. 

5. Panic

The turning point arrives. Investors rush to exit, triggering sharp price declines. Panic selling takes over, and the bubble bursts. 

Examples of Bubbles 

1. Meme Stock Bubble – United States (2021–2022)

This bubble involved stocks like GameStop (GME) and AMC Entertainment (AMC). In early 2021, retail investors, organised mainly through Reddit (r/WallStreetBets), began buying shares of companies heavily shorted by hedge funds. The goal was to create a “short squeeze” by rapidly driving up share prices. 

At one point, GameStop’s share price jumped from under US$20 to over US$400 in just a few weeks without any fundamental change in the company’s performance. AMC followed a similar trend. This was pure speculative buying, and many latecomers suffered heavy losses once prices crashed back to earth in late 2021 and 2022. 

These stocks were overvalued based on traditional valuation metrics, yet people kept buying in the hope that prices would keep rising. Once investor excitement faded, prices dropped rapidly. 

2. Singapore Property Mini-Bubble – 2022–2023

In Singapore, the residential property market saw a rapid price rise between 2022 and early 2023. Factors such as low interest rates, high demand for new homes, and supply constraints led to soaring prices. 

Condos and HDB resale flats saw record prices, with buyers rushing to purchase in fear of future price increases. However, by late 2023, the government introduced new cooling measures and increased supply, leading to a moderation in prices and a slowdown in transaction volumes. 

This example illustrates how rising prices, driven by fear, speculation, and a short supply, can inflate a bubble, even in a regulated market like Singapore’s.
