Cuffelinks Special 250th Edition 2018

Special Edition 250 includes over 30 market experts sharing a mistake that made them better investors.

Since Edition 1 of Cuffelinks, we have focussed on independent expert insights from high-profile finance professionals to deliver useful ideas to our community, now over 35,000 strong.

It's an important time to learn these lessons, as the 88-year-old founder of Vanguard, Jack Bogle, recently said in a CNBC interview:

"I have never seen a market this volatile to this extent in my career. Now that's only 66 years, so I shouldn't make too much of it."

We had a fantastic response from people we approached, but something new happened this time. Disappointingly, some fund managers were prevented from offering a response by their legal and compliance team. It's a sad state of affairs when a fund manager is unable to admit a mistake, as we're all supposed to learn from them. The question we asked was:

"What is an enduring investment lesson you learned from making a mistake?"

We also had responses asking what a 'mistake' really is, such as:

"What is a mistake in investing? Too often managers admit to mistakes (that reveals their deep humility) that weren't mistakes; rather the market went against them. As in bridge, you can make excellent decisions with rotten outcomes and rotten decisions with excellent outcomes."

One famous local fund manager wrote that identifying a mistake can relieve stress:

"Insights from past failures can help boost performance on a new task – and this study is the first, as far as I know, to explain why. The researchers report that writing critically about past setbacks leads to lower levels of the 'stress' hormone, cortisol, and more careful choices when faced with a new stressful task, resulting in improved performance. The study, published in the journal Frontiers in Behavioral Neuroscience, is the first demonstration that writing and thinking deeply about a past failure improves the body's response to stress and enhances performance on a new task."

Another was more skeptical:

"The harsh truth is that I don’t believe any investor really learns from their mistakes in any meaningful way. By this I mean we can easily avoid investing in the same dud company, but that doesn’t stop us investing in other dud companies. We can then develop personal heuristics that steer us away from all companies that have similar traits to the dud one we lost money on, only to find out that some of them turn out to be great investments. The problem of course is that history never exactly repeats.

The reasons we make mistakes can usually find their roots in the human foibles we learn about in behavioural finance (anchoring, confirmation bias, recency bias, etc), and because we are human we keep making them. And the problem with the behavioural finance work is that it’s a very good descriptor of why we have stuffed up in the past, but offers little by way of prescription for future success. I reckon the biggest mistakes we are likely to make comes from over-confidence."

Investors learn from previous experiences, whether or not they are considered mistakes at the time, and sharing the lessons from market professionals may help our readers.

Retirement

Retirement spending is not one-size-fits-all

New data challenges the idea that Australians are underspending their super. The bigger issue may be helping retirees navigate complexity, make confident decisions and use their savings to support security, wellbeing and choice.

Taxation

The missing link in the CGT debate

A little-noticed consequence of Labor’s tax changes could have implications well beyond investors’ tax bills. The issue raises bigger questions about incentives, capital allocation and the drivers of long-term economic growth.

Investment strategies

The surprising beneficiaries of the AI boom

While markets obsess over AI winners, a larger, more predictable growth engine is forming. A surge in electricity demand and infrastructure build‑out reveals the quiet, durable assets evolving beneath the AI story.

Superannuation

When losses in super become irreplaceable

The notion of 'you can afford more risk' assumes that losses can be replaced. Above a $2.1 million super balance the law says otherwise, and a worked example shows the refill takes decades, or never happens.

Retirement

Why I object to ‘hitting a number’ for retirement

Many investors dream of “hitting their number” and walking into retirement. But what if reaching that milestone is the moment they should be asking the tough questions? After all, there's a lot more to life than a high portfolio value.
