Reading cyclicals

Arjun's uncle sells umbrellas. In the monsoon, when it rains every day, he sells hundreds and makes a lot of money. In the dry summer, almost nobody buys an umbrella, and he barely earns anything. His business goes up in the rains and down in the summer, up in the rains and down again - a wave that repeats every year.

Now imagine two friends looking at the umbrella business. One looks in the middle of the monsoon, sees piles of money, and thinks "this business is amazing, it will always be like this!" The other looks in the dry summer, sees empty shelves, and thinks "this business is dying." Both are fooled - because they forgot the wave. The monsoon money will not last, and the summer emptiness will not last either. Each is just one point on a repeating cycle.

Peter Lynch warned that a whole group of companies work like the umbrella seller. He called them cyclicals - businesses that go up and down with the economy. And he found something surprising and back-to-front about reading them: the usual rules flip upside down. A cheap-looking price can mean danger, and an expensive-looking price can mean opportunity. This study is about reading against your instinct.

First, two words. A cyclical is a company whose profit rises and falls with the economy - makers of cement, steel, cars, or chemicals boom when the country is building and buying, and slump when it stops. And P/E is the price of a share compared to its yearly profit: a low P/E normally looks cheap and safe, a high P/E normally looks expensive. For most companies, that rule is a helpful guide. For cyclicals, Lynch said, it flips.

Here is why it flips. At the top of the cycle - the busy monsoon - the cyclical company is earning enormous profit. Since P/E is price ÷ profit, and the profit is huge, the P/E number looks tiny, so the share looks wonderfully cheap. But this is the most dangerous moment! The good times cannot last; when the economy slows, that huge profit will shrink, and the price will fall. The "cheap" P/E was a trap set by a peak that is about to end.

At the bottom of the cycle - the dry summer - the company is earning almost nothing. With profit near zero, the P/E number looks huge, so the share looks terribly expensive. But this may be the moment of opportunity! The bad times will not last forever; when building and buying pick up again, profit will come roaring back. The "expensive" P/E was hiding the fact that profit was temporarily crushed.

So Lynch's read for cyclicals is deliberately upside-down: a very low P/E can be a warning of the top, and a very high P/E can hint at the bottom. With cyclicals you cannot look at profit for a single year and trust it - you must ask where on the wave the company is right now.

illustrative Rapid Steel is a cyclical. In a booming year, when the whole country is building, it earns ₹50 of profit per share. Its share price is ₹250, so its P/E is 250 ÷ 50 = 5 - a very low number that screams "cheap!" A person who did not understand cyclicals rushes to buy, thinking they found a bargain.

Then the building boom cools, as booms always do. The next year Rapid Steel earns only ₹5 of profit per share - one-tenth of before. The price, seeing this, falls to ₹100. Now its P/E is 100 ÷ 5 = 20 - suddenly it looks "expensive," even though the price is far lower than when it looked cheap. The person who bought at the "cheap" P/E of 5 has lost a lot, because they bought at the top of the wave.

A reader who understood cyclicals would have done the opposite: seen that a P/E of 5 in a boom year is a danger signal, not a bargain, and been most interested later, in the gloom, when profits were crushed and everyone else had given up. The wave, not the single year, is the real story.

You cannot see the wave's timing. Knowing a cyclical is at the top does not tell you when it will fall - it might stay high for another year or two. Knowing it is near the bottom does not tell you when it will rise - the gloom can last far longer than you expect. The flip-rule warns you which way the risk leans; it does not hand you a date.

A bottom can also be an ending. Sometimes a struggling cyclical is not resting at the bottom of a wave - it is genuinely dying, and there will be no rebound. A high P/E at a trough is only an opportunity if the cycle actually turns back up. If the whole industry is fading forever, "buy the gloom" simply means buying something that keeps falling. You must judge whether it is a cycle or a slow death.

Not every up-and-down company is a true cyclical. Some profit swings come from one-time events, not a repeating economic wave. Applying the flipped rule to a company that is not really cyclical will mislead you. First make sure the swings truly follow the wider economy, again and again, before you trust the pattern.

India has many cyclicals - cement, steel, cars, sugar, real estate, many chemicals - all rising and falling with how much the country is building and buying. So this reversed-reading skill is genuinely useful here. But two Indian cautions matter. First, the wave can be long and slow; a cyclical at the top can stay there while a whole boom runs its course, and a cyclical in the gloom can stay gloomy for years - patience and timing are hard, and nobody can call the turn precisely. Second, never confuse a passing dip with a permanent decline; you must decide whether an industry will truly cycle back up or is fading for good. The lesson to carry is humble and specific: for cyclicals, do not trust a single year's profit, and treat a very low P/E in good times with suspicion rather than joy.

• First check it is truly cyclical. Does its profit rise and fall again and again with the wider economy? If not, this rule does not apply.
• Never trust one year's profit for a cyclical. Ask where on the wave - top, bottom, or middle - the company sits right now.
• Treat a very low P/E in boom times as a warning, not a bargain. Huge current profit may be about to shrink.
• Treat a very high P/E in gloomy times with curiosity, not fear. Crushed current profit may be about to recover.
• Ask if the bottom is a rest or an ending. A trough is only an opportunity if the cycle will actually turn back up.
• Don't expect to time it. The rule tells you which way the risk leans, never the exact day the wave will turn.
