Ask most investors how they intend to do well in the sharemarket and the answer, in one form or another, is that they plan to pick winners. Ask how they plan to identify those winners and the conversation usually turns to sectors: which industry is about to run, which theme has momentum, which corner of the market the money is flowing into. Both instincts feel natural. Both are largely misdirected. The evidence suggests that long-term returns are driven by the quality of individual businesses, not the labels they sit under — and that the most reliable way to improve a portfolio is not to find the next star, but to remove the weakest holdings and let time do the rest.

The trouble with sector thinking

Sector labels are a filing system, not an investment insight. They tell you what a company is grouped with, not what it is worth. A business classified under mining services may in truth be an engineering company with recurring consumable revenues that grow through commodity upturns and downturns alike. A company labelled healthcare may behave nothing like its sector peers, because its economics rest on distribution capability, patents and management quality rather than on any industry-wide tide.

The deeper problem is that sector thinking encourages investors to buy exposure rather than businesses. The industry line — that a portfolio must hold banks, resources, healthcare and technology in roughly index-like proportions — quietly forces investors into companies they would never choose on merit. Even professional fund managers privately concede the point: mandates oblige them to hold businesses they wish they didn’t own. That restriction is by design, and it serves a purpose, but the purpose is consistency with a benchmark. It caps results at the average of whatever the sector or index happens to produce. An investor answerable only to themselves carries no such obligation, and giving that freedom away is a costly, invisible decision.

Why elimination beats prediction

Predicting which company will be the market’s next star is genuinely difficult — even most professionals, hemmed in by mandates and benchmarks, struggle to do it consistently. The popular response is to give up on selection altogether and buy the whole basket through an index fund. But that answer conceals a symmetry worth naming: by definition, a passive investor can never do better than the market average, because the average is precisely what they have bought — every excellent business and every mediocre one, in whatever proportions the index happens to hold them. Indexing is not a way of winning the game; it is a decision to accept a draw. And it is still a decision — the moment you choose where to put your money, you are an active investor whether you admit it or not.

Here is the asymmetry that changes the game: while winners are hard to predict, losers are comparatively easy to spot. There is far more useful information about weak businesses than about future stars. Deteriorating returns on capital, rising debt, acquisitive management with a poor record, earnings that never convert to cash — the warning signs are visible in the accounts for anyone willing to look. Scan any index and some constituents will disqualify themselves almost immediately.

That observation points to a practical discipline. Rather than hunting for reasons to buy, hunt for reasons to reject. Be as demanding as you like: any credible flaw is grounds for elimination. Only when a business survives every objection does it earn deeper research. The process leaves a small pond stocked with the best fish — a short list of durable, well-managed companies — and concentrates the investor’s limited hours where they can actually compound. Remove the bottom fifth of any index and the remainder, held patiently, has a fighting chance of doing something far better than average.

The honest trade-off every investor faces

None of this is free. Knowing a business well enough to own it through an unpopular stretch — well enough to read a results announcement the way an owner reads a report from their managing director — takes real work. Every investor therefore faces the same honest choice. Do the work yourself, deeply, on a small number of businesses. Do it alongside others, pooling expertise so that hundreds of experienced eyes cover ground no individual could. Or delegate it entirely, through an adviser or a low-cost index vehicle, and consciously accept the average — which, it should be said, is a perfectly respectable outcome and far better than pretending to do the work while actually guessing.

What does not work is the middle path: holding individual companies without understanding them, on the strength of a sector story or a headline. That approach carries all the risk of concentration with none of the protection of knowledge. Everyone has a circle of competence built over a working lifetime; the sensible starting point is to invest inside it, and to be candid about what sits beyond it.

Time does the heavy lifting

The final piece is patience. Over months, share prices swing on sentiment, sector fashion and noise; over decades, they track earnings. A business that grows its earnings steadily will be materially larger in ten and twenty years, and its market value will follow, however erratically the journey unfolds. Periods of undervaluation are not a malfunction of this process — they are the mechanism by which patient investors are paid. When a strong sector falls from favour and drags good businesses down with it, the disciplined response is not to flee the label but to examine whether anything about the business itself has changed. Often nothing has, except the price.

This is also why missing an opportunity is rarely fatal. Markets revisit quality. A well-run company that runs away from fair value will, more often than not, be offered again within a year or eighteen months — to the investor who did the research slowly, kept the short list ready, and could therefore move quickly when price finally met value. The winners, in the end, are not picked. They are what remains after everything else has been shown the door — and then given the one ingredient no strategy can substitute for: time.
