Hint: Not as often as you check the weather.
If checking your investment portfolio was a sport, many South Africans would qualify for the Olympics. Gold medal in Over-Monitoring, silver in Emotional Decision-Making, and bronze for “I Panicked and Sold at the Bottom”.
Let’s get something out of the way upfront: Watching your portfolio too closely is one of the fastest ways to sabotage long-term returns.
Markets move. That’s their job. Your job is to avoid reacting like it’s breaking news every time the JSE sneezes or the rand does what the rand does best – surprise everyone.
So how often should you check your investments? And when does checking become meddling?
Monitoring vs managing: know the difference
There’s a big difference between monitoring your portfolio and managing it emotionally.
- Monitoring is checking that your investments are still aligned with your goals.
- Emotional managing is logging in at midnight because offshore markets were red and now you are questioning every life decision since 1998.
The first builds wealth. The second funds your cardiologist’s private yacht.
The sensible frequency (no, it is not daily).
For most long-term investors, especially those saving for retirement, financial independence, or future income:
- Quarterly check-ins are more than enough
Once every three months allows you to:
- Review performance in context (not panic mode)
- Confirm your asset allocation still makes sense
- Make sure nothing has drifted wildly off course
Checking daily doesn’t make you informed – it makes you anxious. Markets are noisy in the short term, and reacting to that noise usually leads to buying high and selling low. Which, last time I checked, is not a strategy.
What about monthly?
Monthly reviews can make sense if:
- You’re actively contributing large amounts
- You’re close to retirement and managing income drawdowns
- There’s a deliberate strategy in place
If you’re checking monthly just to see how it’s going, ask yourself an honest question: Is this curiosity or control disguised as curiosity?
Annual reviews: the long-term investor’s secret weapon
For disciplined investors with a solid plan, an annual review is often enough.
This is where the real work happens:
- Are your goals still the same?
- Has your risk tolerance changed?
- Has life happened (marriage, kids, business sale, emigration, inheritance)?
Markets change all the time. Life changes are what actually require portfolio adjustments.
Rebalancing: the boring thing that works
Rebalancing sounds dull – and that’s precisely why it’s effective.
Over time, some assets outperform others. Left unchecked, your portfolio quietly morphs into something far riskier (or more conservative) than you intended.
In simple terms, rebalancing is: Selling a bit of what’s done well and topping up what’s lagged – without emotion.
Most investors are well served by:
- Annual rebalancing; or
- Threshold-based rebalancing (for example, if an asset class drifts more than 5%-10% from target).
It’s disciplined, unemotional, and slightly uncomfortable – which usually means it’s the right thing to do.
A South African reality check
We invest in a country with:
- A volatile currency
- Political noise
- Loadshedding (still)
- And a market that can feel small compared to global giants
This makes diversification and discipline non-negotiable.
Constantly reacting to headlines – local or global – is how investors destroy value. The most successful investors I’ve worked with are not the smartest or the most informed.
They’re the most consistent.
The real risk isn’t market volatility
Let’s be blunt.
The biggest threat to your portfolio is not:
- Market crashes
- Interest rate cycles
- Elections
It’s you, armed with a login and a bad day. Good advice, a clear plan, and the ability to do nothing when nothing needs doing – that’s where long-term wealth is built.
If your portfolio needs your attention every week, it’s either:
- Poorly structured, or
- Being used as an emotional support animal
Neither is ideal. Check it with intention. Adjust it with discipline. And then – go live your life.
Portfolios should change when life does – not when markets do.
