📰 Trading news and events: results, RBI days, the Budget and elections

🎯 In 30 seconds: Some market-moving events are on a calendar (quarterly results, RBI policy meetings, the Union Budget, election results) and some are not (a fraud, a regulatory order, a war). Prices react to the gap between the news and what was expected, and they react in seconds, often before you finish reading the headline. On 3 June 2024 the Nifty 50 rose 3.25% on exit polls; the next day, when the real results disappointed, it fell 5.93%. Plan event days before they happen: smaller size, limit orders, no trading in the first minutes, and knowledge of the price bands and circuit breakers that can stop trading altogether.

Listening to the match on the radio

Imagine following a cricket match on a radio that runs a few seconds behind the live feed. When you hear "and that's a six", the crowd in the stadium has already cheered, the bookmakers have already changed their odds and the bowler is walking back to his mark.

That is what trading on news feels like for most people. By the time a result, a policy decision or a breaking story reaches your phone, professional traders with direct data feeds and computer programs have already acted on it. The price you see is the price after the reaction.

Scheduled and unscheduled events

The first step is knowing what is coming. The main scheduled events for Indian shares:

Unscheduled events are the ones nobody can plan for: a large order win, a promoter arrest, an auditor resigning, a fire at a plant, a SEBI order, a sudden change in a government policy, a war or a pandemic. Listed companies must report material events to the exchanges promptly under SEBI's listing rules, so the first official word usually appears on the NSE and BSE corporate announcement pages.

Why reacting to headlines is hard

• Speed. Programs read exchange filings and news wires in fractions of a second. A human tapping an app is minutes behind.
• Expectations. Prices move on the surprise, not the news. A company reporting a 20% profit jump can fall if analysts expected 30%. A rate cut that everyone predicted may barely move the market.
• The overnight gap. News that arrives after 3:30 p.m. is priced in at the next morning's pre-open auction (9:00 to about 9:08 a.m. on NSE). By 9:15 the opening price already reflects it.
• Reversals. The first move is often wrong or overdone. Prices can swing hard one way in the first 15 minutes and the other way by noon.
• Wide spreads. In fast markets the gap between the best buy and sell prices widens. A market order can fill far from the last price you saw.

Results days

Results are the most common event for any single share. Indian companies announce them during or after market hours, and the board meeting date is disclosed to the exchanges in advance, so you can always know which of your shares report this week.

What usually happens:

• Results after the close: the share gaps at the next day's open. Your stop-loss cannot protect you from the gap; see the gap example in Swing trading.
• Results during the session: the price can jump within a minute of the filing appearing on the exchange website. If the share is outside the F&O segment, it can hit its daily price band and lock there.
• The conference call and investor presentation often come later and can change the reaction, because management's comments on the next few quarters matter as much as the past quarter's numbers.

For a beginner, the simplest rule is to be out of a share, or holding a small enough position to survive a gap of two or three times your normal stop, before it reports.

RBI policy days

The RBI's Monetary Policy Committee sets the repo rate, the rate at which the RBI lends to banks. The decision and the policy statement are published on the last day of each meeting, usually followed by the Governor's statement and a press conference. Rate-sensitive shares (banks, finance companies, real estate, autos) and the government bond market react the most.

Often the rate decision itself is fully expected. What moves prices is the stance and the commentary: hints about future cuts or hikes, inflation and growth forecasts, and any changes to rules for banks. Reading the statement, not the headline, is the only way to know what changed. Dates for the year are announced in advance; the 2026-27 schedule was released on 23 March 2026.

Budget day

The Union Budget changes tax rates, government spending and sometimes the rules of the market itself, so the whole market can swing during the Finance Minister's speech. In recent years it has been presented on 1 February. In 2026 that was a Sunday, and NSE and BSE held a full live trading session with normal timings (NSE circular of 16 January 2026).

A budget can change your own trading costs. Budget 2026 raised STT on derivatives from 1 April 2026: on sales of futures from 0.02% to 0.05%, and on sales of options from 0.10% to 0.15% of the premium. Delivery and intraday STT on shares did not change. Changes like these are announced in a speech and then confirmed in the Finance Act, so wait for the official text before acting on a headline.

Election results: 3 and 4 June 2024

The 2024 Lok Sabha election shows how expectations, not news, move prices.

• Monday 3 June 2024. Exit polls over the weekend had predicted a large majority for the ruling alliance. The Nifty 50 rose 733.20 points, or 3.25%, to close at a record 23,263.90.
• Tuesday 4 June 2024. As counting showed a much smaller tally than the exit polls suggested, the market fell hard. The Nifty 50 closed at 21,884.50, down 1,379.40 points or 5.93%, its biggest one-day fall since March 2020. The Sensex fell 4,389.73 points.

Traders who bought on the exit polls lost the whole gain and more within a day. The lesson is not that elections are predictable. It is that nobody, including the exit polls, knew the result in advance, and positions sized for a normal day were exposed to a move several times larger.

Circuit breakers and price bands

Indian exchanges have two kinds of brakes.

Market-wide circuit breakers. If the Nifty 50 or the Sensex, whichever gets there first, moves 10%, 15% or 20% from the previous close, trading across the equity market stops. NSE's rules, as of October 2026:

After a halt, trading restarts with a 15-minute pre-open call auction. The levels are worked out each day from the previous close. In March 2020, during the COVID-19 crash, the 10% level was hit twice, on 13 March and 23 March, and trading stopped for 45 minutes each time.

Price bands on single shares. Shares outside the F&O segment have a fixed daily band of 2%, 5%, 10% or 20% either way. Shares in F&O have no fixed band but a dynamic operating range that the exchange widens in steps. When a share hits its band on news, you may see only buyers (upper circuit) or only sellers (lower circuit) and be unable to trade at all. See The rules every Indian trader runs into.

An event-day plan

1. Know your calendar. Every Sunday, list this week's results for shares you hold or watch, RBI and Budget dates, major data releases and any election counting day.
2. Decide before, not during. For each event, choose one: exit before it, hold a reduced size, or hold as normal because the position is small. Write down why.
3. Size for the gap. Assume the share can move two or three times your normal stop distance overnight. Can you take that loss? If not, cut the size. Hypothetical: 200 shares of Sharma Foods at ₹500 with a stop at ₹485 risk ₹3,000. A results gap of three times that distance, to ₹455, would cost ₹9,000. If ₹3,000 is your limit even on a gap, hold about 66 shares (₹3,000 / ₹45) through the results instead.
4. Wait out the first minutes. Do not place market orders in the first 15 minutes after a big announcement or the 9:15 open. Use limit orders.
5. Read the source. Open the actual filing on the NSE or BSE website or the RBI statement, not a forwarded summary.
6. Review afterwards. In your trading journal, note what you expected, what happened and whether the plan held.

Try it

On NSE's website, open the board meetings page under corporate filings and list five companies reporting results in the next two weeks. For each, note the date, the share's closing price the day before results, and its price at 9:30 a.m. and at 3:30 p.m. on the day after the results are out. Read the results filing itself on the exchange's announcement page and write one line on what surprised the market. Then open the RBI's press release with the MPC schedule and note the next decision date; on that day, record the Nifty Bank's move in the first 30 minutes and by the close. How often was the first move the right one?
