Let us take a real period and look at actual numbers.

Between 2010 and 2015, the Nifty moved from roughly 5,200 to around 8,000. That works out to approximately 9% annual returns in rupee terms.

During the same period, the Nasdaq moved from roughly 2,300 to around 5,000. That translates to approximately 17% annual returns in US dollar terms.

Now imagine two investors starting in 2010 with the same amount of money.

• Investor A puts 100% in India.
• Investor B splits the portfolio: 50% in India and 50% in the US.

Investor A compounds at roughly 9% per year.

Investor B earns a blended return closer to 14% per year before accounting for currency.

That difference of 5%age points annually over five years is massive. Over ten or fifteen years, the compounding effect becomes substantial.

There is another layer here.

Between 2010 and 2015, the rupee depreciated against the US dollar. This means that US returns, when converted back into rupees, were higher than the dollar return alone. We will examine currency more carefully in Chapter 4, but it is important to recognise that currency movements can meaningfully affect final outcomes.

So in this example:

• India-only allocation: ~9% CAGR
• 50% India + 50% US allocation: ~13–14% CAGR before currency
• With currency impact included, the blended return would have been higher

The point is not that the US was “better” than India during that period. The point is that combining geographies changed the overall outcome.

Geographic diversification does not remove volatility. It just changes the sources of return. Over long periods, that difference can lead to a very different compounding journey.
