- Markets open on a Sunday for the first time since 1999 – a rare liquidity event.
- Historical data shows a muted Budget‑day move (≈0.2%) but a 7× larger rally in the following week.
- Capex‑heavy sectors (infrastructure, steel, renewable) could outpace peers after the Budget.
- Technical patterns in the pre‑open session often set the tone for the week.

You missed the last Sunday market opening—don’t repeat that mistake.
Why the Budget Sunday Opening Matters for Indian Equities
On February 1, 2026, the National Stock Exchange and Bombay Stock Exchange will break tradition and trade from 9:15 am to 3:30 pm on a Sunday. The decision, announced in a January 16 circular, aligns the market calendar with the Union Budget presentation at 11 am. For investors, the rarity of a Sunday session means two things: a temporary surge in trading volume and a concentrated window for price discovery before the week’s broader market forces take over. Liquidity spikes can tighten spreads, making it easier to enter or exit positions, but they also amplify volatility when large orders hit the book.
Historical Performance of Nifty on Budget Days vs. Post‑Budget Weeks
Data from the past 15 Budget cycles tells a clear story. The Nifty index averages a modest 0.19% move on the day the budget is delivered, while the Nifty Bank, a proxy for financials, edges up just 0.42%. In contrast, the seven‑day window following the Budget delivers returns roughly seven times larger than the single‑day average. The pre‑Budget week typically sees a modest dip (‑0.52% on average), reflecting investor caution as policy uncertainties loom. Once the budget speech clears the fog, investors re‑price earnings expectations, especially in capex‑intensive industries.
Sector‑Level Implications: Capex‑Driven Winners and Losers
Finance Minister Sitharaman has pledged double‑digit growth in capital expenditure (capex). Historically, such commitments have propelled infrastructure firms, cement makers, steel producers, and renewable‑energy developers. When the budget earmarks funds for highways, ports, or green power, the revenue pipelines for companies like Larsen & Toubro, UltraTech Cement, and Adani Green tighten, often translating into higher forward‑looking earnings multiples. Conversely, sectors that rely on consumption‑driven growth—retail, consumer durables—may lag if the budget skews toward supply‑side spending.
How Peers Like Tata and Adani Are Positioning Ahead of the 2026 Budget
Large conglomerates are already adjusting their exposure. Tata Group’s infrastructure arm has been quietly increasing its stake in government‑linked projects, signaling confidence in a capex‑friendly budget. Adani’s renewable portfolio, now the world’s largest, is set to benefit from any acceleration in clean‑energy subsidies. Both companies have seen modest price appreciation in the pre‑Budget week, suggesting that market participants are pricing in a positive bias. Keep an eye on insider buying trends and strategic partnership announcements in the days leading up to February 1.
Technical Signals to Watch During the Pre‑Open and Live Session
The pre‑open window (9:00 am‑9:08 am) offers a snapshot of market sentiment before the official trading bell. A bullish opening range break (ORB) above the pre‑open high often foreshadows a strong intra‑day rally. Conversely, a failure to hold the pre‑open low can signal weakness. On Budget Sunday, pay particular attention to the 9:15 am open relative to the previous day’s close. A gap up exceeding 0.5% with high volume may indicate that investors have already priced in favorable budget components. Technical tools such as the 20‑day moving average and relative strength index (RSI) can help confirm whether the momentum is sustainable into the week ahead.
Investor Playbook: Bull and Bear Cases for the Next 30 Days
- Bull Case: The budget delivers on its capex promises, triggering a sector rotation into infrastructure, steel, and renewables. Volume spikes on Sunday set a higher baseline, and the Nifty climbs 2‑3% in the following week. Long positions in ETFs tracking the Nifty Infrastructure Index and selective stocks like L&T, UltraTech, and Adani Green outperform.
- Bear Case: The budget falls short of expectations, with modest capex allocations and higher fiscal deficit concerns. Market participants remain cautious, leading to a muted post‑Budget rally. The Sunday liquidity surge dissipates, and the Nifty stalls below 0.5% for the month. Defensive plays in consumer staples and IT become preferable, while high‑beta infrastructure names retrace.
Regardless of which scenario unfolds, the rarity of a Sunday trading session creates a unique entry point. Position yourself early, monitor the pre‑open dynamics, and align your sector bets with the budget’s capex narrative. The real story will likely be written in the week after February 1, not on the day itself.
