Sensex Breaks Below Its April Low to Hit a Fresh 2026 Bottom as Auto Stocks Crack

The Sensex has given up the last line of defence it held for most of 2026. In Thursday afternoon trade the BSE benchmark slid as low as 71,528, just under the 71,545 mark it touched on April 2, setting a new calendar-year low. The Nifty 50 dropped below 22,400 for the first time since that same early-April sell-off, and at one point traded around 22,266, down roughly 1.6% on the day.

The fall was sharp rather than gradual. From an intraday high of about 72,573, the Sensex shed more than 1,000 points in a few hours, and by 2 PM it was down about 1,008 points, or 1.4%, at 71,473. The total market value of BSE-listed companies shrank by roughly Rs 8.7 lakh crore during the session, to about Rs 464 lakh crore.

Auto stocks set the tone

The single biggest drag came from automakers, which reacted badly to their September sales numbers. Bajaj Auto was the worst performer in the Nifty 50, falling about 7% to around Rs 10,060 after weak domestic two-wheeler volumes (see our coverage of its September sales).

The selling did not stay with one company. Mahindra & Mahindra and Maruti Suzuki each fell more than 4%, while Eicher Motors and Hero MotoCorp also lost ground. The Nifty Auto index dropped as much as 4% intraday, making it the weakest sector on the board. Metal, defence and consumer durables indices each lost more than 2%.

Breadth was decisively negative. More than 3,200 stocks were declining on the BSE against fewer than 1,000 advancing, and 41 of the 50 Nifty constituents were in the red at one stage.

Why the floor gave way

Several pressures arrived at once. Brent crude was trading near $99.7 a barrel, up about 1.7%, as uncertainty over US-Iran talks kept supply worries alive. The rupee weakened to about 96.11 against the dollar, from 95.98 at Wednesday's close.

Foreign investors remain the market's most persistent sellers. Foreign institutional investors were estimated to have sold equities worth around Rs 44,000 crore in September alone, extending a two-year stretch of heavy outflows.

Market strategists also pointed to two less obvious factors. One is liquidity: a crowded pipeline of IPOs has been pulling money out of the secondary market at a time when foreign buyers are absent, leaving fewer bids for existing stocks. The other is the Reserve Bank of India's upcoming October policy meeting. With bond yields rising and fears of an inflation spike building, some traders now see a real chance of a rate hike in October, a sharp shift from the easing cycle of 2025.

The calendar added to the caution. Indian markets are shut on Friday, October 2, for Gandhi Jayanti, and traders appeared unwilling to carry fresh positions into a three-day break with crude and global yields this volatile.

The one bright spot

Information technology stocks held onto the gains they made at the open, when a brokerage call on mid-sized IT firms lifted the sector (see our market-open report). The Nifty IT index was still up around 2% in the afternoon, a rare cushion on a day when midcap and smallcap indices fell roughly 1.5% each at their lows.

What to watch

Thursday's break below the April low matters because that level had acted as a floor through several rounds of selling this year. Whether the Sensex can reclaim it after the long weekend is likely to depend on three things: the direction of crude oil, the tone of the RBI's October policy decision, and whether foreign selling finally slows. Until at least one of those turns, analysts expect rallies to meet supply.
