Valuation-driven rotation: follow value, not fashion

Imagine a big open cricket ground on a hot afternoon. When the crowd arrives, everyone rushes to sit on one side - say, near the pavilion, where the famous players walk. That side fills up, gets crowded, hot, and uncomfortable, and the good seats there become "expensive" - you have to squeeze and push to get one. Meanwhile the far side of the ground is almost empty. It has plenty of space and shade, but nobody wants it, because it is not the fashionable side today.

A clever boy named Kabir does something simple. When his side becomes packed and unpleasant, he quietly walks over to the empty, shady side and stretches out in comfort. Later in the match, the crowd's mood changes - maybe the sun moves, maybe the excitement shifts - and everyone rushes to his new side. Now it is crowded. So Kabir moves again, to wherever there is space. He is always drifting away from the packed part and towards the empty part.

Sankaran Naren, a respected Indian fund manager, does something very like this with money across different sectors of the market. A sector is just a group of companies doing similar work - for example, banks, or cement makers, or medicine companies. A fund manager invests other people's money carefully. Naren is known for slowly shifting money out of whichever sector has become crowded and expensive, and into whichever sector has become empty and cheap. This study is about that patient drift - called valuation-driven rotation - where you follow value, not fashion, around the ground.

Two words to hold. Valuation means how dear or cheap a thing is compared to what it actually earns - not just its price tag, but its price next to its worth. A sector can have a high price and still be reasonable if it earns a lot; and it can look cheap only because its price has fallen far below what it earns. Rotation just means slowly moving money from one sector to another over time.

Put together, valuation-driven rotation means: over the years, keep shifting your money towards whatever sector has become cheap on valuation, and away from whatever sector has become expensive. You are not chasing whichever sector is exciting today. You are drifting towards wherever the value has quietly moved.

Why does value keep moving around the ground like this? Because sectors go in and out of fashion. For a few years everyone loves, say, medicine companies; money floods in, prices climb, and that sector becomes dear. While everyone is staring at the fashionable sector, a boring one - say, metal makers - gets ignored, its prices sag, and it becomes cheap even though it is still earning. Then fashion turns: one day the crowd remembers the cheap sector and rushes in, while the once-loved sector, now too expensive, starts to sag. The value has drifted from one side of the ground to the other, just like the shade.

So the reading skill is to keep asking, "which sector has the crowd packed into and pushed dear, and which has the crowd deserted and left cheap?" - and to lean, slowly, towards the deserted-and-cheap side. Naren does not do this in a single afternoon. He rotates gradually, over years, letting the froth build up in the hot sector before stepping away, and letting the cold sector stay cheap and hated for a while before it finally turns. It is the patient walk to the shady side, not a mad dash.

illustrative Aarav's fund can hold two made-up sectors: Software companies (this year's darling) and Steel companies (this year's bore). He measures how dear each is with a simple valuation number - the price you pay for every ₹1 the sector earns. A low number is cheap; a high number is dear.

Right now Software is on fire. People will pay ₹40 for every ₹1 it earns - very dear. Steel is forgotten; people pay only ₹8 for every ₹1 it earns - very cheap. Everything about the mood says "put money in Software." But the valuation says the opposite: Software is crowded and expensive, Steel is deserted and cheap. So Aarav slowly rotates money out of Software and into Steel, feeling foolish while friends brag about their Software gains.

For a year, he looks wrong - Software keeps rising and Steel stays dull. Then the fashion turns. Buildings and factories need steel; Steel's earnings and price rise, and its valuation climbs from ₹8 towards ₹20. Meanwhile Software has become so expensive that it sags, its ₹40 drifting back towards ₹25. The money Aarav rotated into cheap Steel now grows, and the money he took out of dear Software avoided the fall. He never predicted the exact turning month. He simply kept leaning towards the sector with the low valuation and away from the sector with the high one - and waited.

A cheap sector can stay cheap for years. Just because a sector's valuation is low does not mean the crowd will come back soon. Sometimes it stays deserted for a very long time, and you sit there feeling foolish while the fashionable sector keeps climbing. Rotating towards value needs deep patience, because value often takes years to be noticed.

Sometimes a sector is cheap because it is genuinely fading. Not every ignored sector is a hidden bargain. Some are cheap because the world is truly moving away from what they make - a product going out of use, a business the future does not need. Rotating into that is not clever; it is walking towards a corner of the ground that is emptying because it is broken, not because it is out of fashion. Telling "cheap and unloved" apart from "cheap and dying" is the hardest judgement of all.

Rotating too often just burns you out. If you jump sectors every few months chasing small valuation gaps, you end up buying and selling constantly, paying costs and getting whipped around by short mood swings. Valuation-driven rotation is a slow, patient drift measured in years - not a restless hop from sector to sector every season.

In India the fashions of the market shift often, and you can watch them if you pay attention. One year everyone talks about technology shares; another year it is banks; another year it is roads and cement; another year it is medicine. Each fashion pulls the crowd and the prices up, then fades. The idea of quietly leaning towards the ignored, cheap corner while the crowd packs the fashionable one is a genuinely useful eye to develop, and it fits our noisy, mood-driven markets well.

But two things do not transfer easily. First, measuring whether a sector is truly cheap or dear takes real skill - the simple "price for every ₹1 earned" is only a starting hint, and it can mislead. Second, and more important, telling a temporarily-unfashionable sector from a permanently-declining one is genuinely hard, and even experienced managers get it wrong. So a young reader in India can safely learn the shape of the idea - follow value, not fashion, and be patient - while remembering that the real work of judging valuations, and of not walking into a dying sector, takes years to learn and is never a sure thing.

• Spot the crowded side. Notice which sector everyone is excited about and paying dearly for - that is usually the expensive corner to step away from.
• Look at the ignored side. Ask which sector the crowd has deserted and left cheap on valuation - that is where value may be quietly waiting.
• Compare price against earnings, not price alone. A sector is dear or cheap relative to what it earns, so judge valuation, not just the ticker number.
• Check cheap-and-unloved versus cheap-and-dying. Only rotate into a cheap sector that is out of fashion, not one the future is truly leaving behind.
• Drift slowly, over years. Rotate gently and rarely; jumping between sectors every season is not this idea, it is just restlessness.
• Expect to look wrong for a while. A cheap sector can stay cheap a long time, so lean towards value only with patience you can keep.
