The formula behind every great compounding story, high returns reinvested into growth, trailed the Indian market when run as a screen.

We built 186 portfolios from the screen, one for every starting month, held one, three and five years. As with every strategy we test, the range of outcomes tells a fuller truth than the single line, and here the two disagree sharply.

Held one year, the compounders beat the index in about 46% of starts. Held three years, roughly 63%; held five, about 66%, at a median near 22% a year. Patience helped, as it usually does. But unlike the clear winners it never approached a sure thing, and the reason sits in the headline number below.

The shape of it: good years in the middle, famine at the start

Over a single year, half of all starts landed between roughly −21% and +91%, the best year above +142%, the worst near −36%. A generous spread. The trouble is where the lean years fell: heavily in the screen's opening stretch, which is exactly the stretch the single ten year line is forced to live through. Most windows that avoided that opening did respectably. The one everyone quotes did not.

The single run: the famous formula, famously behind

Straight through from 2018, the top thirty compounded at about 7.4% a year against the index's 12.5%, and ₹10 lakh grew to roughly ₹18 lakh while the index reached ₹26 lakh. Worse, the more faithfully you followed the ranking, the worse it got: the screen's ten favourite companies earned barely 1% a year through a 64% fall. The formula's arithmetic is not in question; what the market spent this period doing was repricing the famous compounders that arithmetic points to, and no screen built on fame survives its repricing.

The fall was ordinary; the recovery was not

Across start dates, the worst fall over a five year hold typically reached about 42% and topped out near 55%, no worse than the other small cap screens and gentler than several winners. Falling was not this screen's problem. Its problem was what came after: baskets priced for perfection recover slowly, because the repricing that hurt them is permanent, not cyclical. The clear winners fell as hard and climbed back faster.

What it actually owned

The basket is recognisably the quality growth shelf of the Indian market: Central Depository Services in every single rebuild, Tips Music, Prudent Corporate, capital light businesses earning spectacular returns and growing fast. Nothing about the list is foolish. Everything about it was popular, and popularity is a price.

The equation was never the problem

High returns reinvested into growth really is how fortunes compound; the arithmetic has built every great business story India has. What this test shows is subtler: by the time a compounder is measurable in a screen, it is usually already famous, and fame is paid for in advance. The investors who made fortunes on these businesses bought the arithmetic before it was obvious. The screen, arriving after, bought the same arithmetic at a price that had the future already inside it. Held patiently, across many starts, it still edged the market more often than not. But the lesson worth keeping is the one the ten favourite stocks taught at 1% a year: quality is a fact, and price is what decides whether the fact pays you.

So we took it to Krest, and ran it through the whole test.
