Before they were titans

India has produced extraordinary wealth creation over the past 30 years. Does this mean investors should simply buy the country’s largest companies? History suggests the answer is more nuanced. Some of India's largest companies have been excellent investments. But some of its most extraordinary returns have occurred earlier i.e. while businesses were making the transition from substantial companies into market leaders. 

In other words, there may be an important difference between being big and becoming big.

Motilal Oswal's long-running Wealth Creation Studies provide a useful way of examining this. Its research divides India's listed companies into three groups: Mega companies are the largest 100 by market capitalisation, Mid companies are ranked 101–250, and Mini companies sit below rank 250. The firm's 25-year study from 1995 to 2020 found that companies which started and remained in the Top 100 generated an average share-price return of around 13% per annum. That's a good outcome.

But the ten companies that began between ranks 101 and 250 and subsequently entered the Top 100 returned an average 21% per annum. Four companies made the even bigger journey from below rank 250 into the Top 100. Their average return was approximately 24% per annum. The effect of those differences over 25 years is enormous. ₹100 compounding at 13% becomes roughly ₹2,100. At 21%, it becomes almost ₹11,800. But there's a catch.

Becoming big is rare

It would be easy to interpret those numbers as evidence that investors should simply buy smaller Indian companies. The data says otherwise. Of the companies ranked 101–250 in 1995, 99 subsequently fell below the Top 250. Their average annual return was negative 1%. Of the companies that started below rank 250, the overwhelming majority remained there and generated an average return around zero. 

The exceptional wealth creation wasn't produced by being smaller. It came from the relatively small number of businesses that successfully became much larger. 

And the latest data suggests the phenomenon remains relevant.

What happened from 2020 to 2025?

Companies that were already among India's largest 100 and remained there returned an impressive 29% annually. But 21 of the 150 companies starting between ranks 101 and 250 entered the Top 100. Their average total return was 56% per annum. ₹100 compounding at 29% for five years becomes approximately ₹357. At 56%, it becomes roughly ₹925.

But importantly, only a minority of the starting cohort achieved that transition. Fifty-seven moved in the opposite direction and fell below rank 250. That is what makes this a stock-selection story rather than simply a mid-cap story.

Is this uniquely Indian?

Not entirely. Australia has produced plenty of similar examples. Companies such as Pro Medicus, NEXTDC, Technology One, HUB24 and Life360 have climbed into the S&P/ASX 100 in recent years. So, we shouldn't conclude that companies becoming giants is somehow unique to India. Nor can we yet make a clean claim that India's rate of upward corporate mobility is greater than Australia's. India's historical data ranks companies directly by market capitalisation, while S&P/ASX index membership also incorporates free float, liquidity and index eligibility requirements, making a direct comparison difficult.

The more defensible observation is that India offers a large and rapidly evolving universe of companies competing to become tomorrow's leaders. And the dispersion between those that succeed and those that don't, can be enormous.

Finding tomorrow's giants

That may be the more interesting way to think about investing in India. The argument isn't that investors should avoid India's largest companies. Many are outstanding businesses, and the historical returns from companies that maintained their leadership positions have been strong. Nor is the argument simply to buy smaller companies.

It is that some of India's greatest wealth creation has occurred during the journey from substantial company to dominant company. The difficult part, of course, is identifying those businesses before the transition occurs.

That requires more than finding growth. It requires identifying companies with large addressable markets, durable competitive advantages, strong balance sheets, capable management and the ability to reinvest capital at attractive rates for many years.

India's biggest investment opportunity, therefore, may not simply be owning today's giants. It may be finding tomorrows.
