We see five key indicators that can help investors to recognize a bubble before it bursts.

What exactly is a stock market bubble?

Before identifying the warning signs, it is important to understand what defines a stock market bubble.

A bubble occurs when stock prices rise significantly above their actual value, driven by the speculation rather than fundamentalsInvestors continue to buy not because companies are performing well, but because they believe prices will continue to rise.

While markets often experiment temporary overvaluations a real bubble is powered by hype, excessive optimism and irrational purchasing behaviors. Eventually the bubbles burst, often leading to serious market crashes and financial losses.

Is it possible that today's market is experiencing this situation? Let's examine the signals.

1. Is a compelling story driving the market?

Remember the boom of dot-com of the late 90s? Investors believed that “the internet would have changed everything”, bringing to massive investments in technology stocks, many of which later collapsed.

Wave real estate bubble of the early 2000s? The widespread belief that “property prices never go down” created an overheated market that eventually triggered a global financial crisis.

Every stock market bubble is driven by a narration, a compelling story that captures the public's imagination and makes investors believe that this time it's different.

Are we seeing a similar trend right now? Are some industries being touted as revolutionary, even though they haven’t yet produced real profits?

2. Do stock prices go up regardless of news?

A healthy market responds to economic news, earnings reports and global events. If a company fails to meet earnings expectations, the price of its shares goes down. If the economy Slows, the market often adapts accordingly.

But in a bubble, everything seems to be pushing stocks higher, even the bad news.

• Missed earnings? Stocks continue to rise.
• Economic slowdown? The market continues to rise.
• Interest rates rising? No impact on the growth of the stocks.

When stock prices They are able to ignore fundamentals and appear immune to negative developments, it could be a sign that investors are acting irrationally, driven more by optimism than by logic.

Does today's market reflect this behavior?

3. Are other assets rising uncontrollably?

Stock market bubbles rarely exist in isolation. When excess money pours into the market, often flows into other speculative investments.

We are currently witnessing:

• Cryptocurrencies on the rise again?
• Luxury collectibles, such as rare sneakers, bags and sports cards, selling for record prices?
• Are non-traditional assets like NFTs and digital art making a comeback?

During past market bubbles, we have witnessed the real estate speculation in the 2000s, to the surge of cryptocurrencies in 2017 and the NFT craze in 2021.

4. Are new traders crowding out experienced investors?

Who are today's loudest stock market participants? During the big bubbles, a new wave of investors often emerges, who argue that traditional investor wisdom is outdated. They argue that Legendary Investors Like Warren Buffett “Don’t Understand” the New Economy.

The same thing happened during the boom of dot-com, when experienced investors were told they didn't "understand" internet stocks. However, when the bubble burst, many of these new traders lost everything, while long-term investors they weathered the storm.

If you hear that the old investment rules no longer apply, it is worth asking: Are we in the midst of another speculative bubble?

5. Are stock valuations historically high?

One of the most important indicators reliable of a market bubble is theextreme overvaluation.

Even though stock prices are rising, they need to be supported by earnings growth. If prices are rising at a rate that is unsustainable relative to fundamentals, a bubble may be forming.

Some key questions to ask yourself:

• Price-to-earnings (P/E) ratios are at all-time highs?
• Companies are valued far beyond their actual revenue or profit potential?
• We are seeing increases in 100%+ of shares in a short period of time without any significant business improvements having occurred?

These are red flags that suggest that the investors are evaluating stocks based on excitement rather than financial reality.

Why Should Investors Care About Stock Market Bubbles?

Identifying a bubble early can help investors protect your assets and make smarter financial decisions. If you suspect a blister, it is recommended to:

• Avoid high-risk investments that could collapse.
• Diversify your portfolio in safer activities.
• Be cautious with speculative tendencies that do not have solid foundations.
• Prepare for potential economic downturns which often follow market bubbles.

Recognizing a bubble does not mean predict market crashes, but be prepared.
