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.

Why spending more in early retirement can improve lifetime income

Conventional wisdom encourages retirees to preserve superannuation. But if those likely to qualify for the Age Pension later in life spend a little more today, it may deliver higher lifetime income and a more stable retirement.

Will you run out of money in retirement?

Fear of running out has become a defining retirement anxiety. Why do some retirees die with substantial wealth while others deplete their nest egg? Evidence suggests the answer is more complicated than we think. 

The investment that sidesteps the new tax traps

Tax rules have changed, but many investors are still using yesterday’s strategies. Insurance bonds may offer advantages for those seeking greater control, tax efficiency and certainty about their wealth.

Testamentary trusts have secured the CGT exemption

Treasury’s latest CGT reform draft delivers a win for testamentary trusts and deceased estates, exempting estate-derived gains from the 30% floor. However, questions on death and divorce rollovers remain unresolved.

Meg on SMSFs: What do we think about reversionary pensions these days?

Reversionary pensions have long been a staple of SMSF estate planning, but are they still the best option? Meg Heffron revisits a once-clear favourite and asks whether changing super rules have shifted the balance.

How does the 4% rule stack up?

The 4% rule has long been retirement's gold standard. But after a difficult period for investors, fresh analysis suggests a more conservative approach may significantly improve the chances of making savings last.

Latest Updates

Planning

Testamentary trusts survived the trust tax. The drafting battle has just begun.

The fight over testamentary trusts looked settled. Then the draft legislation arrived. Hidden in a technical detail is a question that could force many families to rethink wills they thought were already future-proof.

Investment strategies

The new capital gains tax trap for your portfolio

Investors have long accepted one portfolio rule without much question. A major tax shift could change that calculation entirely, forcing difficult trade-offs between risk, discipline and an overlooked cost lurking beneath.

Economy

Population growth masks Australia’s productivity problem

For years, investors have benefited from a seemingly reliable growth story. But recent national accounts raise uncomfortable questions about what has really been driving Australia’s economy and whether that can continue unchecked.

Investment strategies

Why tomorrow’s winners may not be today’s index leaders

The stocks that built retirement balances over the past decade now dominate many portfolios. The new challenge is whether these companies can continue meeting the increasingly high expectations embedded in today's share prices.

Investing

What earnings surprises reveal about future returns

Sometimes the most important information in an earnings result isn't the number itself. It's the possibility that the market's assumptions have been fundamentally wrong and future earnings may look very different.

SMSF strategies

Individual SMSF Trusteeship directly liable for ATO fines

A rarely discussed detail buried in SMSF structures could dramatically change who wears the cost when something goes wrong. With penalties rising, a decision many dismissed as administrative may deserve a second look.

Investment strategies

The currency bet you didn’t know you made

Buying global shares means making two bets: on the companies and on the Australian dollar. Most investors consciously choose only the first. Last financial year, the second bet cost 8.5% in returns for many investors.
