Nifty IT was down 19.39% over the 365 days ending with the October 6, 2026 snapshot, while all 10 of its constituents fell that day. Those are separate measures: the index’s one-day decline was 1.10%, and the reported daily breadth does not mean every constituent also lost value over the year.
What the October 6 snapshot shows
Goodreturns reported Nifty IT at 27,990.95 points on October 6, 2026. Its page listed a 1.10% decline for the day, an 8.81% decline over 30 days, and a 19.39% decline over 365 days. It also reported that all 10 constituents fell on October 6. These are figures from a dated market-data page, not live quotes for October 7.

Why “all 10 fell” does not mean all 10 lost over the year
“All 10 stocks fall today” describes the direction of constituent prices on October 6 alone. The 365-day figure describes the index’s performance across a much longer period. Goodreturns’ one-year view showed positive returns for Coforge, Persistent Systems, Oracle Financial Services Software, and Tech Mahindra, even as the index’s reported 365-day return was negative.

There is no contradiction: stocks can fall on a particular day after rising over the preceding year, or rise on a day despite a negative longer-term return. Also, an index-level return is not the same as the return of any one constituent.
How Nifty IT represents the IT sector
Nifty IT is designed to capture the performance of India’s IT segment. The NSE Indices factsheet describes it as a 10-company index calculated using free-float market capitalization. In a weighted index, constituents do not necessarily contribute equally to the index’s move; a company’s influence depends on its weight. That is why counting how many stocks declined (daily breadth) is distinct from measuring the index’s percentage return.

The cited October 6 market-data page reports prices, returns, and the number of constituents that fell, but it does not establish why the decline happened. The available evidence therefore does not support attributing that session’s move to earnings, AI concerns, currency changes, client spending, or another specific factor.
An NSE-hosted Business Standard clipping describes an earlier Nifty IT selloff in April 2026 following weak HCLTech quarterly performance and outlook. That report concerns the April episode, not October 6, and cannot be used to explain this later session: Business Standard clipping hosted by NSE, April 2026.

How to read the figures as an investor
- Check the measurement window before comparing percentages: one day, 30 days, and 365 days answer different questions.
- Do not treat a negative index return as proof that every constituent had a negative return over the same period.
- When comparing individual stocks, use the same start and end dates and the same return window for each one.
- Use the October 6 figures as a historical snapshot, not as a current market quote or an explanation of what moved prices.
