Investment Strategies Explained

There is no best investment strategy. There are recognised approaches, each designed for a different objective, each with a characteristic way of going wrong. This lesson describes the main ones and is deliberately even-handed: none is recommended, and each is presented with its failure mode attached.

Strategy follows objective

The question "which strategy should I use" cannot be answered without first answering three others: what is the money for, when might you need it, and how much decline can you tolerate without selling?

That last one is the one people get wrong. Almost everyone overestimates their tolerance for loss when the market is calm. The relevant test is not what you believe you would do if your portfolio fell by a third — it is what you actually did the last time something you owned fell sharply. A strategy you will abandon at the worst moment is worse than a more modest one you can hold.

Value investing

Value investing seeks securities trading below an estimate of their intrinsic worth, on the reasoning that the market periodically misprices businesses and that the gap may close over time.

In practice it means estimating what a business is worth from its financials and buying only at a meaningful discount to that estimate. It requires the fundamental analysis toolkit and, more demandingly, a willingness to buy things that are unpopular.

How it fails. A share can be cheap because the business is genuinely deteriorating — the value trap. Cheap shares can also stay cheap for years, and being right about value while being wrong about timing is, for anyone who cannot wait, indistinguishable from being wrong. Value investing also requires you to hold positions while others are making money elsewhere, which is psychologically harder than it sounds.

Growth investing

Growth investing seeks companies whose revenue and earnings are expanding rapidly, accepting a higher valuation on the expectation that the growth continues.

The focus is forward-looking: the size of the market a company can address, the durability of its advantage, the rate at which it is expanding. Traditional valuation ratios often look expensive, and growth investors argue that is the point.

How it fails. The high valuation embeds an expectation, and expectations disappoint. A company priced for rapid growth that merely grows moderately can fall very hard, because both the earnings and the multiple applied to them contract at once. Growth strategies also tend to be concentrated in a small number of sectors, which means less diversification than the number of holdings suggests.

Dividend and income investing

Dividend investing prioritises companies that distribute cash to shareholders regularly, with the objective of producing income rather than only capital appreciation.

The appeal is tangible: a return that arrives as cash rather than as a paper gain. It typically favours established, profitable, slower-growing businesses.

How it fails. Dividends are not contractual. A company may reduce or omit a dividend at any time, and the companies most likely to do so are often those whose yield looked most attractive beforehand. Chasing the highest yields systematically selects for companies in trouble, because yield rises as price falls. Dividend strategies also concentrate in a few sectors, and the income is taxable, which affects the real return.

Index and passive investing

Rather than selecting individual companies, index investing seeks to hold a broad market in proportion, accepting the market's return rather than attempting to beat it.

The arguments in its favour are strong and largely empirical: costs are lower, no security selection skill is required, diversification is automatic, and a substantial body of evidence indicates that most active managers do not beat their benchmark consistently after fees.

How it fails. You get the whole market, including its declines, with no mechanism for avoiding them. In a market where a few very large companies dominate the index, a capitalisation-weighted approach concentrates you in exactly those companies — which is not what most people imagine they are buying. And in a market where index products are limited, the practical options may be narrower than the theory assumes.

Rupee-cost averaging

Investing a fixed amount at regular intervals regardless of price. When prices are low the fixed amount buys more units; when high, fewer.

Its real benefit is behavioural rather than mathematical. It removes the decision of when to invest, which is the decision people handle worst, and it makes investing a habit rather than a series of judgements made under emotional pressure.

How it fails. It is not protection against loss. Averaging into a company that continues to decline simply means buying more of a falling asset — the technique has no view about whether the underlying investment is sound. It also cannot help with the decision of what to buy, only when.

Buy and hold

Buying with the intention of holding for years, on the reasoning that trading costs and taxes compound against you and that time in the market matters more than timing it.

How it fails. It is often used as a euphemism for refusing to reassess. Holding an investment whose original rationale has been demolished is not patience, it is avoidance. Buy and hold requires periodic honest review of whether the reason you bought still applies — which is precisely why writing that reason down at purchase is worth the two minutes it takes.

Active trading

Frequent buying and selling to profit from shorter-term price movements, usually informed by technical analysis.

How it fails. The costs are certain and the edge is not. Every trade pays commission, taxes and the bid-ask spread, and those accumulate relentlessly regardless of whether the trade was a good idea. Research across markets consistently finds that the majority of frequent individual traders underperform a simple buy-and-hold approach after costs. It also demands time and emotional discipline that most people with other jobs do not have available.

This is not an argument that no one should trade. It is an argument that trading should be entered into with clear eyes about what is being paid for the attempt.

Asset allocation

Rather than a strategy for picking securities, asset allocation is a decision about how much to put in different kinds of asset — equities, fixed income, cash, real assets — according to objective and risk tolerance.

It receives less attention than security selection and, in most research, explains considerably more of the variation in portfolio outcomes. The mix matters more than the individual choices within it.

Related to it is rebalancing: periodically restoring the intended proportions after market movement has shifted them. It enforces selling some of what has risen and buying some of what has fallen, which is difficult to do and is exactly why writing the rule down in advance helps.

Choosing between them

A few honest observations rather than a recommendation.

These approaches are not mutually exclusive; most real portfolios combine several. The strategy you can actually maintain through a bad period beats a theoretically superior one you abandon. Costs and taxes reduce every strategy's return and are among the few variables you control. And past performance — of a strategy, a fund or a share — is not a reliable guide to what follows.

If you are choosing between approaches for the first time, the more useful question is not which produces the highest return in a good year, but which you would still be following after a bad one.

What every strategy pays

Whatever the approach, the same charges apply: brokerage commission agreed with your broker, CDC and NCCPL charges, the SECP fee, and taxes including withholding tax and capital gains tax. Strategies involving more frequent trading pay these more often, which is the single most predictable difference between them.

Our Fees, Charges & Taxes page explains each line and who sets it. No rates are quoted in this lesson because they are revised periodically and a figure written here would eventually be wrong.

How each one fails

Collected in one place, because the failure modes are more useful than the descriptions:

• Value — the value trap, and cheap staying cheap for years.
• Growth — expectations priced in, then disappointed, with multiple and earnings falling together.
• Dividend — dividends cut, and high yields selecting for distress.
• Index — the full downside, and concentration in whatever dominates the index.
• Averaging — averaging steadily into something that keeps falling.
• Buy and hold — patience used as cover for not reassessing.
• Active trading — certain costs against an uncertain edge.

Frequently asked questions

The decision behind the decision

Most discussion of strategy focuses on which one produces the highest return. The more useful question is which one you can actually follow — through a year when it does not work, when something else is obviously doing better, and when the sensible thing feels wrong.

None of the above is a recommendation, and none of it accounts for your circumstances. If you want a view that does, that is a conversation with a qualified adviser, not a lesson on a website.
