**IT Sector’s Weight in BSE Sensex Hits 18-Year Low Amidst Challenges**
The combined weight of IT companies in the BSE Sensex has fallen to its lowest point in 18 years, according to Bloomberg data. Their representation in the broader Nifty 50 index has also reached a decade low. Currently, IT stocks account for only 11.3% of the Sensex, a significant drop from 18.56% in late 2021 and the lowest since it dipped to 8.8% in 2007. Among the top five IT stocks in the Sensex are Tata Consultancy Services Ltd, Infosys Ltd, HCL Technologies Ltd, and Tech Mahindra Ltd, while Wipro Ltd was removed from the index last year.
This decline coincides with the launch of OpenAI’s ChatGPT in November 2022, which is viewed as a pivotal moment for India’s approximately $283 billion IT services sector. The rise of automation, coupled with ongoing visa issues affecting labor mobility in the US, has disrupted traditional business models, leading to slower revenue growth and declining stock prices, which in turn has reduced their index weights.
The downturn is also evident in the Nifty index. Analysts from Motilal Oswal Financial Services noted that while IT services have maintained a stable profit share of 15% over the past four years, their weight in the Nifty has dropped to a decade low of 10%, down from a peak of 19% in December 2021. This reduction in index weight reflects a relative decline in the market capitalization of these tech giants, as a company’s index weight is determined by its market cap relative to the total market cap of the index.
Since the beginning of the year, shares of the five largest IT firms have experienced significant declines: TCS has fallen by 23.47%, Infosys by 17%, HCLTech by 14.74%, Wipro by 17.14%, and Tech Mahindra by 9.97%. In contrast, the BSE Sensex has risen by 8.64% during the same period, highlighting the sector’s struggle to regain investor confidence.
The financial outlook for these companies has also deteriorated, as evidenced by their price-to-earnings (P/E) ratios reaching multi-year lows. TCS (23.7 P/E) and Infosys (24.4 P/E) are trading at their lowest levels in at least five years, while HCLTech (25.8 P/E) and Wipro (20.3 P/E) are at three-year lows. A lower P/E ratio indicates a weak growth outlook and reduced valuations, reflecting investor sentiment regarding the industry’s near-term prospects.
Amit Chandra, vice-president of HDFC Securities, attributes this decline to a combination of factors, including automation and geopolitical uncertainties, which have collectively impacted the IT sector’s performance.

**What factors have contributed to the decline in IT stocks’ weight in the BSE Sensex?**
The decline in IT stocks’ weight is primarily due to the launch of innovative technologies like ChatGPT, the rise of automation, and ongoing visa issues affecting labor mobility in the US, all of which have disrupted traditional business models and led to slower revenue growth.
