What Is a Cyclical Stock — and What Is a Defensive Stock?

When you look at a list of FTSE 100 sectors, you will notice that some industries — mining, construction, travel — tend to boom when the economy is growing and struggle when it shrinks. Others — food retail, utilities, pharmaceuticals — just quietly keep selling what people need, recession or not. This split is one of the most useful frameworks in investing: cyclical stocks versus defensive stocks. Getting your head around it will help you build a more deliberate portfolio rather than picking shares at random.

What makes a stock cyclical?

Earnings that track the economy

A cyclical company sells goods or services that people and businesses tend to delay or reduce when money is tight. In an economic boom — rising wages, strong confidence, cheap credit — demand for cyclical products surges. Revenues climb, profit margins widen, and share prices often follow. In a downturn, the reverse happens: spending pulls back sharply, profits dip, and cyclical shares can fall hard.

The key word here is discretionary. People can choose to put off buying a new car, delay renovating a house, or skip a foreign holiday when their finances feel squeezed. Companies that depend on those choices feel the pinch immediately in their earnings. That is what makes them cyclical — their profitability rises and falls with the economic cycle.

Which FTSE sectors tend to be cyclical?

The FTSE 100 contains a clear cluster of cyclical sectors:

• Housebuilders and construction (e.g. Barratt, Taylor Wimpey) — new home buying is tightly linked to mortgage rates and consumer confidence. When rates rise or jobs feel shaky, completions fall.
• Mining (e.g. Rio Tinto, Antofagasta) — demand for copper, iron ore, and other commodities is driven by industrial activity worldwide. Global growth slows, mining revenues follow.
• Travel and leisure (e.g. easyJet, InterContinental Hotels) — holidays and business trips are among the first things cut when household budgets tighten.
• Banking (e.g. NatWest, Lloyds) — loan demand rises in expansions and falls in recessions; credit losses increase when borrowers struggle.
• Non-food retail (e.g. Marks & Spencer clothing) — spending on clothes, electronics, and furniture tracks consumer confidence closely.

It is worth noting that “cyclical” does not mean low quality. Rio Tinto and easyJet are well-established FTSE constituents — they are simply more sensitive to the direction of the economy than a water company or a pharmaceutical firm.

What makes a stock defensive?

Demand that holds through downturns

Defensive companies sell products or services that people need even when they are cutting back. Recessions do not stop people buying food, taking medicine, paying their electricity bill, or keeping the water running. Because demand for these things stays relatively steady through the economic cycle, the companies providing them tend to enjoy steadier earnings, lower share-price volatility, and — often — more reliable dividends.

The classic defensive characteristic is inelastic demand: the amount people buy barely changes with price or economic conditions. A household will not cut back much on paracetamol because of a recession, but it might easily skip a city break or delay replacing the sofa.

Which FTSE sectors tend to be defensive?

• Consumer staples (e.g. Unilever, Tesco) — everyday food and household products keep selling in good times and bad.
• Utilities (e.g. National Grid, Severn Trent) — people still need electricity and clean water when the economy slows.
• Pharmaceuticals (e.g. AstraZeneca, GSK) — illness does not follow the economic cycle; prescription volumes hold up.
• Tobacco (e.g. British American Tobacco) — an established habit; demand tends to fall slowly even as health awareness rises.
• Telecoms (e.g. BT) — broadband is now treated by most households as an essential, not a luxury.

Why it is hard to time the switch

In theory, the strategy looks obvious: load up on cyclicals before a boom begins, then rotate into defensives just before a recession hits. In practice, almost no one gets this timing right consistently — not even professional fund managers who spend every working day watching economic data.

The problem is that the economy does not send a warning bell when the cycle turns. Recessions are only confirmed in the data after two quarters of negative growth — by which point share prices in cyclical sectors have often already fallen significantly. The same applies at the other end: by the time it is obvious that a recovery is under way, a lot of the cyclical rally is already priced in.

For challenge participants, constantly trying to rotate between cyclicals and defensives at exactly the right moment often leads to selling cyclicals too early in a rally, or switching too late and catching the downturn anyway. Understanding risk and reward means accepting that timing the market is genuinely difficult, even with the best intentions.

A more useful question to ask yourself is: if economic news turns bad tomorrow, how would each of my holdings likely react? Knowing the answer in advance means you can decide whether you are comfortable with that level of exposure before it happens, rather than panicking when headlines turn negative.

How to use this in the Student Investor Challenge

The challenge gives you a virtual £100,000 portfolio and real market prices to work with. Here is how the cyclical/defensive framework can sharpen your thinking:

• Check your sector balance. A portfolio heavily concentrated in mining stocks and housebuilders will perform brilliantly in a bull market but can take large losses when economic data disappoints. Is that a trade-off you are comfortable with?
• All-defensive is not a winning formula either. A portfolio built entirely of utilities and pharmaceutical companies rarely wins the challenge outright. Defensive shares tend to lag when markets are rising strongly because investors rotate into higher-growth cyclical sectors instead.
• Use the mix consciously. Think of cyclicals as the engine of growth and defensives as the shock absorbers. Most thoughtful portfolios contain both. Understanding diversification and asset allocation goes hand in hand with the cyclical/defensive split — they are all about deliberately spreading risk.
• Look at recent profit history. When you are researching a company, check whether its earnings swing widely with the news cycle or stay roughly flat year on year. That pattern is often the clearest clue to which camp it sits in. A company that reported record profits in 2021 and a sharp loss in 2020 is almost certainly cyclical; one whose profits barely budged during the pandemic is probably defensive.

FAQ

Is every company either cyclical or defensive?

Most lean one way or the other, but some sit in between. A supermarket, for instance, sells mostly everyday staples — food, cleaning products — which are defensive. But its non-food range of clothing, electronics, and homewares is more discretionary, giving it a mild cyclical tilt. No label is completely fixed, and companies can shift over time as their business mix changes.

Are cyclical stocks riskier?

They carry more earnings volatility, which usually means wider share-price swings. That is a genuine form of investment risk. But cyclicals also offer more upside in strong economies — their profits can rise dramatically when conditions are favourable. Risk and potential return travel together: higher volatility cuts both ways.

What are some FTSE 100 defensive stocks?

AstraZeneca (pharmaceuticals), National Grid (electricity and gas networks), Unilever (food and household brands), and Severn Trent (water) are commonly cited. They are not immune to bad news — individual companies can still face regulatory problems, pricing pressure, or management missteps — they are simply less sensitive to the economic cycle than cyclical peers.

Should I pick all defensives in the challenge?

Not necessarily. The challenge rewards portfolio growth over the competition period. Purely defensive portfolios often lag in rising markets because defensives tend to trail cyclicals when economic confidence is high and investors chase higher-growth opportunities. A thoughtful mix — and understanding why you own each share — tends to work better than concentrating entirely at one end of the spectrum.
