Automating your investing

The most effective investment technique available to an individual is removing themselves from the process.

Why defaults matter

The evidence.

Automatic enrolment substantially increased pension participation in every country that introduced it, which is a demonstration of the power of defaults over intentions.

Automatic escalation of contributions increases saving rates.

And research on trading frequency consistently finds that more discretionary activity produces worse outcomes.

Which together suggest that the fewer decisions a system requires, the better it performs.

What to automate

The list.

Contributions, by standing order on payday, before spending happens.

Contribution increases, either by an annual escalation feature where offered or by a diarised annual review.

Investment of contributions, so that money does not sit in cash awaiting a decision.

Dividend reinvestment, which accumulating funds do automatically.

Rebalancing, either through a multi-asset fund that does it internally or through a diarised rule.

And the review itself, scheduled rather than triggered.

Why timing contributions is the wrong instinct

The common error.

Holding contributions in cash awaiting a better entry point requires the timing judgement that the evidence suggests is not achievable.

Money contributed regardless of market level buys more when prices are low, which is the mechanical benefit.

And the decision not to invest this month is a decision, made monthly, with the same poor expected value each time.

Which is why the standing order should be set and not revisited.

The behavioural function

Beyond convenience.

Automated contributions continue through declines, which is exactly when discretion would stop them.

Automated rebalancing buys what has fallen, which is exactly what discretion resists.

And the absence of a monthly decision removes the monthly opportunity to be influenced by news, sentiment and comparison.

Which means automation is not primarily about saving effort — it is about removing the points at which behaviour intervenes.

The multi-asset shortcut

The most complete automation.

A single global multi-asset fund at an appropriate risk level, contributed to monthly, rebalances internally and requires no allocation decisions.

Which reduces the entire ongoing management to one standing order.

It costs slightly more than the components and removes the decisions that cost more than the difference for most people.

And target date variants additionally adjust the risk level over time, which removes another decision at the cost of an embedded assumption about retirement.

What cannot be automated

Which requires attention.

The initial decisions: objectives, horizon, allocation, account type, platform.

Responses to changed circumstances: income, dependants, health, horizon.

Cost reviews, since charges change and cheaper equivalents appear.

Tax allowance use, which has annual deadlines.

And the annual review itself, which should be diarised.

Which is a small amount of work concentrated into an annual session rather than distributed as continuous low-level attention.

Adding friction to the rest

The complement to automation.

Remove trading apps from devices.

Turn off price notifications.

Remove saved payment details from any speculative platform.

Impose a mandatory delay before acting on any idea.

And require any change to be written down with the reasoning before execution, which alone eliminates a substantial proportion of impulses.

The failure modes

What to watch.

Contributions failing due to insufficient funds, which is prevented by timing them after payday.

Automated purchases sitting in cash because the investment instruction was not set up.

Contributions continuing into an account that is no longer appropriate.

Amounts becoming inappropriate as income changes.

And the false sense that no attention at all is required, which is where cost drift and allowance deadlines are missed.

Setting it up

Practically.

Choose the account and platform.

Choose the fund or funds.

Set the standing order for the day after payday.

Set the automatic investment instruction, so the money is invested rather than held.

Set a calendar reminder for the annual review.

Write the policy document.

And then, deliberately, do not look at it until the review.
