GDP Growth vs. Corporate Earnings Growth: Why They Can Diverge

Two Growth Rates That Rarely Match

"India is the fastest-growing major economy, so Indian stocks must do well." The argument is common and only partly right. GDP growth and company earnings growth are related, but they measure different things and can diverge for long stretches.

Real vs Nominal

GDP growth is usually reported in real terms, after removing inflation. Company profits are reported in nominal terms, in actual rupees. The right comparison is with nominal GDP.

In the April to June 2026 quarter, India's real GDP grew 7.8% and nominal GDP grew 10.3%, according to MoSPI. A company whose profits grew 8% that quarter was growing slower than the economy in rupee terms, not faster.

The Listed Universe Is Not the Economy

Listed companies are a small and unusual part of India's economy.

• Missing sectors. Agriculture, small and informal businesses, and most government activity have no listed shares.
• Different weights. The Nifty is weighted heavily toward financial services, IT, energy and consumer companies, not toward the sectors that make up most of GDP.
• Foreign revenue. IT services and pharma companies earn much of their revenue abroad, so their growth depends on the US and Europe as much as on India.
• Formalisation. When business shifts from small informal firms to large listed ones, listed profits can grow faster than the economy without the economy growing any faster.

Margins Swing, GDP Does Not

GDP measures the total value of output. Profits are what is left after costs. When margins change, profits can move much faster or slower than revenue.

Illustrative example. An economy's nominal output grows 10%, and so does a company's revenue, from ₹1,000 crore to ₹1,100 crore.

A one-point change in margin turns 10% revenue growth into anything from roughly zero to 21% profit growth. Across the whole corporate sector, margins move with commodity prices, interest rates, wages and competition.

This is why the share of corporate profits in GDP rises and falls over time. In India, it fell to a low around FY20 and recovered strongly afterwards. One brokerage report put the profit share of GDP at about 4.3% in FY26.

A Worked Example: Sector Mix

Illustrative example. Imagine an economy where agriculture grows 3%, manufacturing 7%, and financial services and IT 12% in nominal terms. Suppose agriculture makes up a fifth of GDP but almost none of the stock index, while financials and IT make up half the index.

An index tilted toward the fastest-growing sectors can show faster earnings growth than the economy as a whole, with no change in margins. The reverse is also possible. If the index is heavy in a sector going through a downturn, such as IT during a global slowdown, index earnings can lag even while domestic GDP grows strongly.

So before comparing index earnings with GDP, check which sectors each one is really measuring.

Policy Can Move the Profit Share

Profits after tax also depend on tax rates. In September 2019, India cut its base corporate tax rate for companies choosing the new regime from 30% to 22%. That lifted post-tax profits for many companies without any change in their business. Lower interest costs after companies reduced debt, and stronger balance sheets at banks, also helped profits recover after FY20.

These are one-time shifts. Once a tax cut has been absorbed, it does not keep adding to growth year after year.

Recent Divergence

Recent years show both directions. Through much of 2025, Nifty earnings growth slowed to single digits for several quarters while the economy kept growing at around 7% in real terms, one of the reasons foreign investors cited for selling. Then in the June 2026 quarter, Nifty companies reported profit growth of about 18%, the highest in ten quarters, according to Motilal Oswal, well above nominal GDP growth of 10.3%.

Neither pattern lasts forever. Margins that expand eventually stop expanding, and margins that shrink eventually recover.

The Long-Run Limit

Over very long periods, total corporate profits cannot grow much faster than nominal GDP, because profits cannot become the whole economy. So assumptions that index earnings will grow well above nominal GDP for decades deserve suspicion. Over shorter periods of three to five years, margins, sector mix and formalisation can create large gaps in either direction.

Habits for Comparing Growth

1. Use nominal GDP when comparing with earnings.
2. Check index sector weights against the sectors driving GDP.
3. Track margins, not just revenue, to see where profit growth comes from.
4. Look at profits as a share of GDP to judge where the cycle is.
5. Be wary of long-run earnings forecasts well above nominal GDP.

The Reframe

GDP tells you how fast the economy's pie is growing. Earnings tell you how big a slice listed companies are keeping. Investors are paid from the slice, not the pie.
