Podcast: Taming the Herd: How to Navigate Bubbles, Biases, and Big Market Moves

The Human Side of Market Bubbles

Speculative bubbles are nothing new. As The Finance Ghost notes, “there’s something new, something shiny, it’s a little bit scarce, and suddenly you have the potential for a hype trade to kick in.” Investors often move together, driven by FOMO and the desire to be right. Kingsley Williams reflects on how herd mentality and biases like action bias and confirmation bias can lead to costly mistakes.

Biases That Trip Up Investors

Satrix has presented on common investor biases, including action bias (the compulsion to do something), confirmation bias (seeking information that supports your beliefs), and cognitive dissonance (holding onto bad investments hoping for a turnaround). Kingsley emphasises the importance of a long-term, set-and-forget strategy, using professional advice and letting compounding work its magic. 

Lessons from Market History

Kingsley shares his experience through major market events, from the dot-com bubble to the global financial crisis and Covid. The dot-com crash saw the Nasdaq-100 drop 81% from its peak, taking 12 years to recover. Yet, those who stayed invested saw extraordinary returns over the long term. The lesson? Diversification and patience pay off. 

Are We in a Bubble Now?

Valuations in developed markets are high, especially in US tech, but Kingsley argues that today’s giants have proven track records and profitability. While bubbles are only clear in hindsight, markets tend to reflect available information efficiently. Diversification and investing for the right term remain key. 

The Role of Social Media and Retail Investors

Social media has the potential to amplify herd behaviour and feedback loops, making bubbles form and burst faster. However, it could also contribute to greater price discovery as a diversity of views are expressed on different platforms.  However, there is a bigger risk of retail investors moving prices in less liquid securities, whereas institutional investors dominate the trading volumes in larger stocks. The Finance Ghost warns that meme stocks and crypto are especially vulnerable to speculative bubbles. 

Cyclical Sectors: Mining and Property

Mining and property are classic cyclical sectors. Kingsley and The Finance Ghost discuss how timing and incentives can drive booms and busts, and why ETFs offer a way to play themes without concentrated risk. The key is to avoid chasing fads and to stay diversified. 

Wisdom from Warren Buffett

Quoting Buffett: “An index fund that they never touched would have done the job. Instead, many investors have had experiences ranging from mediocre to disastrous.” This was primarily due to high costs, due to excessive trading or high investment management fees, decisions based on stock tips and fads, and a start and stop approach to the market, marked by untimely entries and exits. The message is clear: stick with low-cost, diversified investments, avoid timing the market, and only if you insist on trying to time your equity market participation, be fearful when others are greedy, and greedy when others are fearful. 

Final Thoughts: Don’t Get Too Close to the Elephant

The Finance Ghost’s analogy: don’t put yourself two metres from an angry elephant with your money. Most investors are better off with a boring, diversified approach, saving the wild bets for a small part of their portfolio. Kingsley agrees: “Absolutely. That’s the way to manage 90% of your money.”
