Why Sensex and Nifty Jumped: Oil's Fall, Foreign Buying, and What It Means for Your SIP

On 23 October the Sensex closed at 73,123.83, and ₹21 lakh crore of market value had gone in four sessions. By 2:20 pm on Thursday 5 November it stood at 79,228.06, up 8.35%. The Nifty 50 was on course for a sixth straight rise. If you stopped looking at your SIP last month, the screen looks very different today. This piece explains what drove the jump, what has not changed, and what the numbers say for a SIP investor. It follows our article on why the market fell.

Indian market figures for 5 November are from about 2:20 pm, with the market still open, so they will differ from the close. Earlier figures are closing values from NSE and BSE. Flows are from NSDL and the exchanges. This is explanation, not advice, and nothing here is a forecast or a recommendation to buy or sell anything.

How big the jump is

The rise is broad: 2,619 shares were up and 946 down at 2:22 pm. It was also fast. The Nifty's lowest close of the year was 22,231.80 on 8 October. It had climbed only 2.1% by 28 October. Then came six rising sessions in a row, which supplied about 80% of the whole recovery. Today is the Nifty's third-biggest daily rise of 2026 so far.

The total value of BSE-listed companies was ₹494.42 lakh crore at the 4 November close, against ₹452.41 lakh crore on 23 October. Do not read all of that ₹42 lakh crore as a rise in prices. Jio Platforms listed on 28 October and alone added about ₹13 lakh crore.

Force one: oil fell faster than it rose

When we wrote about the fall, crude above $100 was the first cause. Its reversal is the first cause now.

These are press-reported futures prices. The US government's spot series, which runs higher, fell from $120.15 on 30 October to $107.03 on 3 November. The reasons given are hopes of a negotiated end to the US-Iran war, talks mediated by Qatar, and shipments through the Strait of Hormuz close to pre-war levels. The Democrats' midterm win added to those hopes, because investors expect Congress to limit further military action.

India buys most of its oil from abroad and pays in dollars. Cheaper oil means a smaller import bill, less pressure on the rupee and on inflation, and lower costs for companies that burn fuel. Today's list shows this: IndiGo was up 5.72% and Tata Motors Passenger Vehicles 5.39%, while ONGC, which sells oil, was down 2.07%.

The warning: this is hope, not a deal. A senior Iranian official told Reuters the two sides remain far from an agreement, and attacks in the strait continued this week. A reversal could be just as quick.

Force two: foreign investors came back

Foreign investors sold ₹48,056 crore of Indian shares in October up to the 23rd. In November the direction has flipped.

That is ₹14,863 crore in three reports, each covering the previous day's trades. The exchanges' provisional figure for 4 November adds ₹7,284 crore. On that same day, Indian institutions were net sellers of ₹3,712 crore. So foreign money is doing the lifting for now, and Indian funds are selling into it. Banks and finance companies led today: Bajaj Finance was up 6.76%, Shriram Finance 6.56% and ICICI Bank 5.07%.

Force three: lower US yields

The US 10-year Treasury yield eased from 5.15% on 19 October to 4.90% on 4 November. The Federal Reserve held rates at its 28 October meeting, though two members wanted a rise. Lower US yields make Indian shares look less costly next to safe US bonds, which is one reason foreign money can return. It is a modest move so far, and 4.90% is still high.

What has not changed

The same size of bounce faded in April

This is the part most market reports leave out. It is not the first rise of about 10% this year.

The Nifty has now reached almost exactly where April's rally stopped. That proves nothing about what happens next. A market can pause at a level or go through it. It is simply a reminder that a sharp rise and a lasting recovery are different things, and only time shows which one this is.

What it means for your SIP

We used the same example as last month: ₹10,000 invested in the Nifty 50 on the first trading day of each month from January. On 23 October, ten instalments of ₹1 lakh in total were worth ₹93,847, down 6.2%.

Three things stand out. Selling near the low was what cost money: about ₹8,000 on ₹1 lakh in under two weeks. Pausing cost far less, because the units stayed invested. A SIP recovered sooner than a lump sum: ₹1 lakh invested in one go on 1 January is still worth only ₹93,801, down 6.2%, while the SIP is in profit. Its average buying level of about 24,022 is well below January's 26,146. Only four months' instalments are under water: 7 of the 11 are in profit, including the one of 2 November, at 23,440.80, which is already up 4.6%.

The trap on the other side. The same arithmetic can mislead. Six good days do not show that carrying on was right, any more than last month's fall showed it was wrong. The April bounce would have looked just as reassuring at the time. And nobody could have known in advance that these would be the good days: that is the whole difficulty with stepping out and hoping to step back in.

What a jump does not change. If the money is for a goal more than five to seven years away, one week tells you little either way. If you need it within two or three years, a market rise is not a reason to feel safe; equity was risky for that money last month, and it still is. If your EMI went up after the rate rise and the SIP strains your budget, that problem has not gone away either. Indian investors put a record ₹32,490 crore into SIPs in September. AMFI's October figures will show how they reacted to the fall.

The returns use the Nifty 50 price index at 2:20 pm on 5 November. They leave out dividends, fund costs and tax, and a real fund will differ. The first trading day of February was the Budget session on Sunday 1 February. Past moves do not predict future ones.

What to watch next

• US-Iran talks and Brent: the single biggest swing factor. Watch whether Brent holds below $100.
• NSDL's daily figures: whether foreign buying lasts beyond a few sessions.
• 8 November: Muhurat trading for Diwali. It is a short, symbolic session and tells you little about the year ahead.
• Around 10 November: AMFI's October data on SIPs and fund flows.
• Around 15 November: India's October trade figures, including oil and gold imports.
• 2 to 4 December: the RBI's next policy meeting. Cheaper oil makes a further rise less likely only if it lasts.

Frequently Asked Questions

Why did the Sensex go up today? Mainly because oil fell sharply on hopes of an end to the US-Iran war, after the Democrats' win in the US midterms, and because foreign investors have turned buyers. Banks, finance companies and auto shares led the rise.

Why does a fall in oil lift Indian shares? India imports most of its oil. Cheaper oil cuts the import bill, supports the rupee, eases inflation and lowers costs for many companies. Oil producers such as ONGC can fall on the same news.

Is the market's correction over? Nobody can know. The Nifty is about 10% above its October low and about 7% below its January high. A rise of the same size in April faded, and the index went on to a new low.

Should I stop or increase my SIP now? This site does not give investment advice. As arithmetic, a SIP started in January has moved from a 6.2% loss to a 2.1% gain in under two weeks, which shows how little a short period says. Your goal, your time horizon and your monthly budget matter far more than this week's move.

Have foreign investors come back to India? They bought ₹14,863 crore of shares across NSDL's first three reports of November, after selling ₹48,056 crore in October to the 23rd. A few sessions do not make a trend.

Why did small caps rise less today? Today's rise is led by large banks and finance companies. Over the period since 23 October, though, the Smallcap 100 is up 8.12%, about the same as the Nifty, after falling harder.
