What happened

The Nifty 50 closed at 22,698.85 on 28 October 2026, down 50.90 points, while the Sensex fell 352.64 points to 72,246.03 in its second consecutive session of losses. The primary drag came from the Nifty IT index, which dropped 1.98% in a single session. Infosys led the decline with a fall exceeding 3%, and TCS, HCL Technologies, and Tech Mahindra also saw significant selling. Together, Reliance Industries, Infosys, and Bharti Airtel accounted for over 107 points of the Nifty 50's decline on the day.

The selling in technology stocks was not limited to one session. Concerns have been building around the health of global technology spending, particularly from clients in the United States and Europe. On 28 October, Brent crude climbed about 1.36% to US$115.40 per barrel amid reports of an attack on a Saudi Arabian refinery, which prompted investors to re-evaluate the inflation and margin outlook for Indian companies that earn revenues in US dollars but bear a large share of their costs in rupees. With the US Federal Reserve's policy announcement also pending, institutional investors globally trimmed positions in risk assets, and large-cap IT stocks in India bore much of that caution.

The broader market told a different story. Small-cap and mid-cap indices outperformed, with the Nifty Smallcap 100 rising 0.90% and the Nifty Midcap 100 advancing 0.43% on the same day. The Nifty Auto index gained 1.45%, pointing to confidence in domestically oriented sectors. Foreign institutional investors were net buyers to the tune of ₹4,240 crore even on a day of headline-index weakness.

Why this matters

IT stocks carry a disproportionate weight in the Nifty 50 and Sensex. When Infosys, TCS, Wipro, HCL Technologies, and Tech Mahindra all decline simultaneously, headline indices can fall even when the majority of stocks in the broader market are rising — which is precisely what happened on 28 October. This distortion matters for passive investors holding index funds or exchange-traded funds who own the full IT weight in their portfolio without realising the concentration.

The deeper concern for long-term IT investors is whether the current drag is cyclical or structural. Higher US interest rates typically slow corporate IT spending as companies protect cash. A strong US dollar and softening discretionary budgets in developed markets can reduce growth guidance from IT majors during quarterly earnings. Additionally, IT revenues reported in US dollars face currency headwinds if the rupee strengthens. None of these pressures are new, but they are converging simultaneously, which is why the selloff feels sharper.

Action plan

Do not confuse a sector correction with a business collapse. India's major IT companies remain profitable and cash-generative; the current selling reflects macro uncertainty rather than fundamental deterioration.

If you already hold IT stocks through diversified equity mutual funds, avoid the temptation to switch out at current levels; the positive breadth in mid- and small-cap segments indicates the overall market is not in distress.

Monitor the US Federal Reserve's upcoming decision. A pause or a softer-than-expected statement could prompt a quick reversal in IT stocks that have sold off ahead of the announcement.

For new money, consider staggering entry through a systematic investment plan rather than lump-sum investing into IT-heavy funds until crude oil levels and US rate direction become clearer.

Check whether your portfolio is overweight in large-cap IT. If more than 30% to 40% of your equity exposure is concentrated in this sector alone, diversifying into auto, banking, or pharmaceutical names may reduce overall portfolio volatility.

Bottom line

The IT-driven decline in the Nifty is partly a function of index composition rather than a signal of broad market distress. The headwinds — elevated crude oil prices, a cautious Fed, and slowing global IT spending — are real but well-known. Patient investors who already hold diversified equity funds have little reason to alter course.
