October 2026 Stock Market Outlook: Earnings, Interest Rates, Key Events to Watch

India's economy grew 7.8% in the April to June quarter. The Nifty 50 still lost 6.1% in September, marking its worst month since March. That gap shapes the question for October. Can strong growth at home outweigh pressure from oil, the dollar, and foreign selling?

Where the Market Stands

The Sensex closed at 72,480.29 on September 30. The Nifty ended at 22,620.45. The Sensex fell 5.8% in September, its second straight monthly drop. The Nifty sits about 14% below its 52-week high of 26,373. Forty of the 50 stocks ended the month lower. Auto, IT, and banking stocks fell most on September 29, while metals and pharma held up.

Why Foreign Money is Leaving

Foreign investors sold USD 2.7 billion of Indian shares in September. Net selling this year has reached USD 26.8 billion. Much of the pressure is coming from outside India. Global central banks, including the US Federal Reserve, raised rates in September. Higher rates make dollar assets and developed-market bonds more attractive than emerging-market stocks.

The rupee adds to the strain. It slipped past 96 per dollar in September, close to its May record low of 96.96. The RBI stepped in to slow the fall. A weaker rupee can reduce the dollar value of foreign holdings when converted back into dollars. That can lower the appeal of Indian shares, even when company results look healthy.

Oil adds to the pressure. India imports most of its crude. Brent crude has stayed near USD 100 a barrel in recent weeks. Higher prices widen the import bill, weigh on the rupee, and lift inflation.

Local funds have helped. Domestic institutions kept buying and absorbed part of the selling. Some market commentary has pointed to slower auto sales and weaker railway freight. Outside forces explain much of the fall, though not all of it. Flows can reverse fast. A slowdown inside the economy would take longer to repair.

RBI Policy and Inflation

The RBI has held its repo rate at 5.25% for four straight meetings. The next decision is due on October 7. In August, the RBI raised its growth forecast for the year ending March 2027 to 6.7%. Retail inflation reached 4.82% in August, its highest level since December 2024. The RBI expects prices to peak in the October to December quarter.

The central bank is dealing with strong growth, rising prices, and a weak rupee at the same time. ICRA has flagged the risk of a rate hike before December. Banks and other rate-sensitive stocks are the most exposed to the RBI's tone. The tone of the RBI's statement may matter more than the decision itself.

Earnings Face a Tougher Test

Second-quarter results start with TCS. HCL Tech and Infosys follow. IT stocks enter the season under heavy strain. The Nifty IT index fell more than 11% in September on worries about spending by US clients. 

Kotak expects a muted quarter. It sees TCS revenue rising only 2.8% from a year earlier. A weaker rupee usually helps IT exporters. Kotak expects weak revenue growth to offset that gain.

Some market estimates put profit growth at 13% to 14%, down from 18% to 19% in the first quarter. Squeezed margins, higher costs, and tougher year-ago comparisons explain the slowdown. With crude oil high, comments on costs will matter. Changes in expected future earnings can matter more to valuations than the latest reported growth rate. These results will show whether the recent weakness is spreading.

What to Watch

Five items deserve close attention. They are Brent crude, US Treasury yields, the rupee, foreign fund flows, and earnings revisions. India's growth story remains intact. Whether shares reflect it depends on how much of the pressure comes from outside the country.

Final Thoughts

The next test comes after October. The RBI meets again in early December, and third-quarter results arrive in January. Those dates will show whether strong growth is reaching company profits and where oil and the rupee stand by then.

FAQs

1. Why did the Nifty fall in September despite 7.8% GDP growth?

Pressure came largely from outside India. Foreign investors sold USD 2.7 billion of shares, global central banks raised rates, the rupee slipped past 96 per dollar, and Brent crude stayed near USD 100. Strong growth did not offset these forces, and the Nifty lost 6.1% for the month.

2. How does a weak rupee hurt Indian shares?

A falling rupee cuts the dollar value of foreign holdings when converted back into dollars. That lowers the appeal of Indian stocks for overseas investors, even when company results look healthy. It also raises the import bill, adding to inflation.

3. What should investors expect from the RBI's October 7 decision?

The RBI has held the repo rate at 5.25% for four straight meetings, while August inflation hit 4.82%, its highest since December 2024. The central bank faces growth, rising prices and a weak rupee together. ICRA has flagged a possible hike before December, and the tone of the statement may matter more than the decision itself.

4. Why are IT stocks under the most pressure this earnings season?

The Nifty IT index fell over 11% in September on worries about US client spending. Kotak expects TCS revenue to rise just 2.8% year on year, and weak growth may cancel the usual benefit of a weaker rupee. TCS reports on October 8, followed by HCL Tech and Infosys.

5. Which indicators matter most for markets in October?

Five items deserve close attention: Brent crude, US Treasury yields, the rupee, foreign fund flows and earnings revisions. Together they show whether the pressure is easing, staying sticky or turning into currency stress.
