Share Market Rules That Are Still True in a Bad Year

Most share market advice is written for a rising market, which is why so much of it stops being repeated during the years when it would actually have been useful.

The rules below are the ones that hold up in a difficult year, which is the only period worth testing advice against, and none of them requires a view about where anything is going.

Decide the Horizon Before Anything Else

Money needed within a year and money not needed for a decade have to be handled in completely different ways, and mixing them causes most avoidable damage.

Every other decision follows from this one, which is why advice that starts with a stock to buy has skipped the part that determined the outcome.

Keep an Emergency Reserve Separate

Money set aside for the unexpected is what prevents investments being sold at the worst possible moment for reasons unconnected to markets.

Building the reserve first looks like a delay and is in fact what protects everything that follows, as investment advisory sets out.

Position Size Decides Whether Being Wrong Matters

The proportion of your capital in any single holding determines whether an ordinary mistake is a lesson or a serious problem.

No amount of research changes that arithmetic, and no source of ideas can make the decision for you.

Concentration Is How Plans Fail

A holding large enough to matter converts a temporary setback into a permanent one, regardless of how sound the reasoning was.

Most people who lose a substantial amount in the market did so in one position rather than across many.

Diversification Means Different Behaviour

Holdings that rise and fall together are one position with additional paperwork, whatever number of company names appears in the account.

What matters is whether they respond to different things, which is worth checking before the fourth or fifth purchase.

Never Borrow to Invest

Leverage converts a temporary fall into a forced sale, which is how otherwise sound plans end permanently rather than temporarily.

The absence of borrowing is what allows time to do the work that everything else depends on.

Costs Are Certain and Returns Are Not

Brokerage, product charges and tax treatment together form a number that compounds against you over the periods people actually hold investments.

Reducing total cost is the only improvement available that does not depend on anything going right.

Frequency Is a Cost Decision

Every transaction has a cost, so an approach requiring constant activity carries a structural disadvantage before any question of skill arises.

This applies to investing exactly as it applies to trading, as intraday tips describes for the shorter horizon.

Know What the Business Does

Being able to state in one sentence what a company sells and who pays for it is a low bar that a surprising number of holdings fail.

Positions failing it are the ones sold at the worst moment, because there was never any reasoning available to hold on to.

Write Down Why You Bought

A note recording the reasoning at the time of purchase is what allows a decision to be evaluated later rather than remembered selectively.

Without it, lucky outcomes and good decisions look identical, and the next decision is no better informed than the last.

Write Down What Would Make You Sell

Deciding in advance what change in the business or in your circumstances would end the holding prevents the decision being made by the price.

Holdings without such a condition are usually kept until the discomfort becomes unbearable, which is rarely the right moment.

A Recommendation Is Not a Decision

A suggestion to buy something leaves the size, the horizon, the exit and the fit with everything else entirely undecided.

Those four determine the outcome and all of them remain yours, however good the source was.

Ideas That Follow the Price Are Late

Recommendations arriving after something has already risen substantially describe what happened rather than anticipating anything.

By the time an idea circulates widely it is generally reflected in the price, which is why acting late is a recognisable pattern of loss.

Forecasts About Levels Are Not Usable

Predictions of where an index will finish the year are wrong often enough to be unusable, however confidently they are delivered.

Nothing in a sound plan depends on that number, which is a useful test of whether the plan is sound.

Check Registration Before Paying for Advice

Where advice is charged for, registration for that specific activity is verifiable independently and determines what recourse exists.

It is the first check rather than the last, as choosing an advisor sets out.

Understand How Any Adviser Is Paid

Fees paid by you and commissions paid by product providers create different incentives, both legitimate when disclosed and both worth knowing.

The answer should be specific, and advisory fees explained covers what each structure implies.

Free Advice Has a Price

Where nothing is charged directly, the cost usually sits inside whatever is recommended and is frequently larger than a transparent fee.

Asking who is paying for the recommendation generally produces a clear answer worth having before acting.

Contribute Regularly Rather Than Cleverly

Adding a fixed amount on a schedule removes the timing decision, which is a judgement wrong often enough to be unusable.

It also removes the most common reason contributions stop, which is waiting for a better moment that never announces itself.

Increase Contributions Before Chasing Returns

In the early years the balance is small enough that additional contributions matter more than any difference in performance.

Raising the amount when income rises is the most effective action available at that stage.

Time Matters More Than Timing

The period over which money stays invested affects the result more than the rate of return, because growth compounds on itself.

Interruptions are expensive in a way that never appears as a loss on any statement.

Behaviour Decides More Than Selection

Selling during a fall and buying after a rise converts an ordinary return into a poor one, and it is the most common way results are damaged.

That input is entirely within your control and receives almost none of the attention that stock selection does.

Review Annually, Not Daily

An annual review of allocation, costs and whether the reasons for holding still apply is sufficient for almost any arrangement.

More frequent review produces activity rather than information, as investment advisory services describes.

Keep Trading Money Separate

Short-horizon trading is a different activity with different rules, and mixing it into long-term holdings damages the assessment of both.

Keeping them in separate accounts makes each one honestly reviewable.

Simplicity Has Measurable Value

A complicated arrangement that sits half-implemented delivers nothing regardless of how well it would have worked on paper.

A plan that is understood is a plan that survives the periods when following it feels uncomfortable.

The Rules That Fail in a Bad Year

Anything requiring a forecast, anything requiring borrowing and anything requiring you to act quickly all stop working when conditions turn.

That is a reasonable test to apply to any advice before adopting it, as advisory services for beginners sets out.

Ignore Comparisons With Other People

Publicly visible accounts of investing are selected towards the decisions that worked, which makes an ordinary year look like failure and prompts changes nobody needed.

Comparing your position against your own plan, rather than against someone else’s reported outcome, is the only comparison that carries any information at all.

Expect Several Bad Years in a Working Lifetime

Periods where holdings fall substantially and stay there are a normal feature of the market rather than evidence that something has gone wrong with your approach.

Deciding in advance how you will behave during one is considerably easier than deciding while it is happening, which is when the decision is made worst.

FAQs

What should be decided first?

The horizon for each pot of money. Every other decision follows from it, and mixing horizons causes most avoidable damage.

How large should a single holding be?

Small enough that being wrong is a lesson rather than a serious problem. Concentration is how most plans fail.

Does diversification mean owning many names?

No. Holdings that move together are one position. What matters is whether they respond to different things.

Why avoid borrowing to invest?

Because a temporary fall becomes a forced sale, which ends a plan permanently rather than temporarily.

How much difference do costs make?

A great deal, because they are certain and compound. Reducing them improves results regardless of what markets do.

How often should holdings be reviewed?

Annually. More frequent review produces activity rather than information.

What test should any advice pass?

Whether it still works in a bad year. Anything requiring a forecast, borrowing or speed usually does not.
