Is 27% profit growth really 27%? This Q2 results season, the answer is: partly. Motilal Oswal expects Nifty 50 profits to grow 27% year on year in the July to September 2026 quarter. That would be the fastest growth in 17 quarters.
Three quick checks show how much of that is new growth. The rest comes from a weak comparison, a weaker rupee and a few strong sectors.
Why Q2 results look bigger this earnings season
Every quarterly result is compared with the same quarter a year earlier. That comparison is called year on year, or YoY. If last year's quarter was weak, this year's growth looks large even when the business has not changed much.
That is the set-up this quarter. In the July to September 2025 quarter, Nifty 50 profits grew just 2% YoY, according to Motilal Oswal's review at the time. It was the sixth quarter in a row of single-digit growth.
So the 27% forecast is real, but it starts from a low step. The three checks below help you see how high the business has actually climbed.
Check 1: compare with last year's base
The first check is to look two years back, not one. This removes most of the effect of a weak or strong comparison quarter, which analysts call the base effect.
Here is the arithmetic for the Nifty 50 forecast. Imagine profits of ₹100 two years ago:
| Quarter | Profit (₹) | Growth YoY |
|---|---|---|
| July to September 2024 | 100 | |
| July to September 2025 | 102 | 2% |
| July to September 2026 (forecast) | about 129.5 | 27% |
Over two years, ₹100 becomes about ₹129.5. That works out to about 13.8% a year. Healthy, but closer to half the headline than all of it.
You can run the same check on any company. Find its YoY growth for this quarter and for the same quarter last year, then look at the two together. A big jump after a bad year is a recovery, not a new trend.
Check 2: strip out the rupee
The second check matters for any company that earns in dollars, such as IT services exporters. When the rupee weakens, each dollar of revenue converts into more rupees. Reported growth rises even if the company sold no more than before.
Companies that earn abroad often report growth in constant currency. This is growth calculated as if exchange rates had not moved. It tells you what the business did, separate from what the currency did.
TCS's Q2 result shows how big that gap can be. Its revenue rose 11.2% in rupee terms, to ₹73,188 crore. In dollar terms, revenue rose only 2.4%, to $7,642 million. Working back from those two figures, each dollar of TCS's revenue brought in about 8.6% more rupees than a year earlier.
So most of TCS's rupee growth came from the exchange rate, not from new business. If the rupee strengthens later, the same effect works in reverse.
Check 3: see who is carrying the number
The third check is about breadth. An index total can rise sharply because a few sectors surge, while most companies grow slowly.
Motilal Oswal's sector forecasts for this quarter show how uneven the picture is expected to be:
| Sector (Motilal Oswal coverage) | Expected profit growth YoY |
|---|---|
| Telecom | 71% |
| Metals | 44% |
| Oil and gas, excluding oil marketing companies | 34% |
| PSU banks | 27% |
| Private banks | 24% |
Metals and oil and gas earnings move with global commodity prices, which can turn quickly. A forecast that leans on them is more fragile than one spread evenly across consumer, industrial and financial companies. Brokerage previews have also warned that high commodity costs could squeeze margins in other sectors.
When you read a strong aggregate number, ask which sectors produced it. Then ask whether the company you hold is in one of them.
Worked example: reading TCS's Q2 result
TCS kicked off the season on 8 October 2026. Here is its result put through all three checks, plus one more line worth reading: margin.
Operating margin is the share of revenue left after running costs, before interest and tax. A falling margin means costs grew faster than revenue.
| Measure | Q2 FY26 | Q2 FY27 | Change |
|---|---|---|---|
| Revenue (₹ crore) | 65,799 | 73,188 | +11.2% |
| Revenue ($ million) | about 7,463 | 7,642 | +2.4% |
| Operating profit (₹ crore) | 16,565 | 17,553 | +6.0% |
| Operating margin | 25.2% | 24.0% | down 1.2 points |
Read across the rows and the story changes. Rupee revenue grew 11.2%. Dollar revenue grew 2.4%. Operating profit grew about 6%, slower than revenue, because the margin fell from 25.2% to 24.0%. Compared with the previous quarter, constant-currency revenue grew 1.3%.
None of this makes the result good or bad. It tells you what drove the headline, which is the point of reading a result.
What these checks cannot tell you
The checks clean up the growth number. They do not tell you whether a share is worth buying or selling at today's price.
That depends on what the market already expected, which is a question of valuation. A company can post strong underlying growth and still see its share price fall, if investors had expected more. Reading results is one part of fundamental analysis, not the whole of it.
Slower real growth is also not automatically a warning. A large company growing 6% in operating profit through a difficult year may be doing well. The checks give you the right number to judge, not the judgement itself.
Tools such as a stock screener can help you compare that number across companies in the same sector.
