Why the biggest investment risk is often what you don’t see

Former Wall Street Journal columnist Morgan Housel once wrote: “Risk is what’s left over after you think you’ve thought of everything.”

That idea has stayed with me. We spend so much time trying to predict, model, and prepare for what might go wrong, but the biggest dangers are often the ones we never even considered.

After spending years working closely with financial markets and investors, my own understanding of risk has evolved.

What I’ve learnt is simple: risk isn’t universal.

It changes depending on who you are, what you own, and what you need your money to do. Importantly, asset managers and individual investors often talk about ‘risk’ as if they’re speaking the same language, but they’re not.

For most asset managers, risk is defined as permanent capital loss.

The focus is at the security or portfolio-construction level:

Diversification;
Position sizing;
Stop-losses;
Derivative protection; and
Risk budgets and guardrails

These are all tools designed to ensure that no single investment can catastrophically impair the portfolio. This type of risk is known. When you buy a share or a bond, you accept upfront that markets move, mistakes happen, and losses are possible.

Most individual investors in South Africa don’t think about risk this way.

What investors want is sensible risk-taking that gives their capital the best chance to grow above inflation.

Investor risk tolerance isn’t fixed; it shifts as life circumstances change.

A young professional with a long-time horizon may be comfortable with higher volatility, while someone approaching retirement becomes more sensitive to drawdowns that could affect their income. Major life events, changing jobs, starting a family, selling a business, or entering retirement all reshape the balance between required returns and emotional comfort.

Understanding that your perception of risk will evolve is critical to ensuring your investment strategy evolves with you.

I’ve personally experienced this.

My grandmother entrusted me with her investment portfolio when I was still a wealth manager. At the time, the strategy made perfect sense. Her capital was conservatively invested, the income was stable, and on paper everything was working exactly as planned.

Then life intervened.

She had an unfortunate fall and broke her femur. Overnight, medical expenses surged, and the level of care she required at her retirement village increased materially. Nothing had gone ‘wrong’ in the portfolio. Markets hadn’t crashed. The investments hadn’t failed. But her circumstances had changed, and with them, the definition of risk.

Suddenly, decisions that once felt prudent became constraints.

Capital preservation mattered, but so did liquidity and income certainty. At just over 90 years old, her ability to tolerate volatility was limited, and her margin for error was effectively zero. The real risk wasn’t market loss. It was the possibility that her capital could no longer support the life she needed to live.

That experience fundamentally changed how I think about risk. It reinforced that the greatest threats to an investor’s outcome are often invisible until the moment they become unavoidable.

I’ve seen the opposite problem too.

A younger investor, early in his career, earning well and saving consistently, but deeply uncomfortable with volatility. The portfolio was conservatively positioned, designed to avoid the discomfort of the market. It felt safe.

Years later, the issue wasn’t losses, it was progress. Returns lagged the progress of his life. As responsibilities increased, expenses did too, and it became obvious that the portfolio had never been given the opportunity to do the heavy lifting required of it.

There was no single bad year to point to. No dramatic mistake. Just a long stretch of underexposure to growth when time was the greatest asset.

The risk wasn’t what the investor experienced; it was what they quietly missed out on.

South Africans investors generally want three things:

Growth above inflation;
The ability to draw down sustainably; and
A level of volatility they can emotionally tolerate.

Even if they don’t use the jargon, what most investors really care about is risk-adjusted returns, not just high returns at any cost, but returns that justify the volatility required to achieve them.

Here’s where the unseen risk creeps in.

What happens when an investor’s tolerance for volatility doesn’t match the return they actually need to sustain their lifestyle?

This is the quiet risk that derails many financial plans, the risk of outliving your capital because your portfolio never had the chance to grow fast enough.

When this mismatch occurs, investors face three possible choices:

Move up the risk curve: Accept higher volatility than you’re truly comfortable with and hope the long-term returns make up for it.
Adjust your lifestyle: Acknowledge that your current risk profile cannot realistically produce the returns required, meaning you either draw down less or accept the real possibility of capital depletion over time.
Find better risk-adjusted returns within the same risk band: Seek out an asset manager with a stronger track record of generating excess return for the same level of risk. This allows investors to potentially improve long-term outcomes without increasing volatility, arguably the most elegant solution. The difficulty can be finding an asset manager whose investment philosophy and process is tailored to optimising absolute returns within controlled volatility targets.

When we think about risk, we tend to imagine market crashes, geopolitical shocks, recessions, and black swans. Financial markets are forward-looking, so these events typically get priced in quickly and digested into future growth and earnings projections.

Those are real risks, but typically not the biggest danger for most long-term investors.

The biggest danger is the slow, silent erosion of purchasing power, the moment your portfolio falls behind your lifestyle needs and inflation, forcing decisions you didn’t plan for.

Lifestyle longevity risk is what keeps most investors up at night.

Like all meaningful risks, it’s usually the one you don’t see coming.

Now consider an asset manager with a multi-decade-long track record of elevating investor returns while keeping risk constrained, generating some of the strongest inflation-beating, risk-adjusted outcomes in the market.
