What moved the market

NIFTY closes higher as crude prices fall sharply

Indian equity benchmarks ended Friday's session on a mixed but broadly positive note, with the NIFTY 50 gaining while the IT sector weighed on sentiment.

The NIFTY 50 closed at 23,346, up 0.33% for the day, supported by a steep drop in global crude oil prices and broadly positive cues from Asian markets. The NIFTY Bank index rose 0.54% to close at 56,359, reflecting relative strength in financial stocks. The SENSEX, however, ended virtually flat at 74,295, down a marginal 0.03%, suggesting that gains were uneven across the broader index composition. Midcap and smallcap segments outperformed large caps, advancing over 1% during the session. India VIX, a measure of near-term market volatility, fell sharply by 7.36% to 11.39, indicating that traders were pricing in lower uncertainty heading into the weekend.

The NIFTY IT index was the clear underperformer, declining 1.03% to 28,855. Technology stocks faced pressure, consistent with global trends around interest rate expectations and concerns about US technology spending. On the institutional flow front, both Foreign Institutional Investors and Domestic Institutional Investors were net buyers in the cash segment. FIIs purchased a net of approximately Rs 600 crore, while DIIs added a net of around Rs 1,020 crore, providing a degree of underlying support to the market. The Indian rupee remained largely stable, with the USD/INR reference rate at 95.94, down 0.02% on the day, though the currency has faced a broader weekly decline amid global interest rate pressures.

Global & geopolitical watch

Crude slides, US opens higher, BOJ disappoints

  • Brent Crude. Brent crude fell sharply by 4.54% to close at 100.06 US dollars per barrel, a move that eased cost-pressure concerns for import-dependent economies such as India. Softer crude prices were cited as one of the primary tailwinds for domestic equities during Friday's session.
  • US Markets. The S&P 500 and Nasdaq opened higher in the US session on Friday, with investors responding positively to the decline in oil prices, though signals from broader macroeconomic conditions remained mixed. The Dow Jones opened relatively flat as market participants continued to assess conflicting data points.
  • Bank of Japan. The Japanese yen fell to a two-week low against the US dollar after the Bank of Japan's latest interest rate hike failed to meet market expectations, with two policymakers dissenting from the decision. The outcome has raised questions among investors about the pace and conviction of further monetary tightening in Japan.
  • Eurozone Bonds. Eurozone government bond yields were on track for their first weekly decline since early August, as investors reduced their expectations of additional European Central Bank rate hikes. US Treasury yields steadied after the benchmark 10-year yield had briefly crossed 5% earlier in the week.
  • Gold. Gold on COMEX edged down 0.16% to 4,393 US dollars per troy ounce, equivalent to approximately Rs 1,35,495 per 10 grams, as a degree of risk appetite returned to global markets following the fall in crude oil prices.
  • Indian Bonds. Indian government bonds recorded a fifth consecutive weekly loss, pressured by a US Federal Reserve rate hike of 25 basis points and RBI liquidity measures that have kept domestic bond market sentiment cautious. Global yields reaching multi-decade highs have added to the headwinds facing domestic fixed-income markets.

Free-float market-cap weighting: what it is and why it shapes the indices you track

When you hear that the NIFTY 50 or SENSEX moved by a certain percentage on a given day, that number is not a simple average of 50 or 30 stock prices. Both indices use a method called free-float market-capitalisation weighting to decide how much influence each company has on the overall index level. Understanding this method helps explain why a sharp move in one or two large companies can drive the headline index number even when most stocks are broadly stable, as was visible today when NIFTY IT's 1.03% decline and NIFTY Bank's 0.54% gain pulled the NIFTY 50 and SENSEX in slightly different directions despite both tracking the broader Indian market.

An index weighted by free-float market capitalisation reflects only the shares that are actually available to ordinary investors in the open market, not the total shares a company has issued.

Market capitalisation is calculated by multiplying a company's total number of shares by its current share price. However, not all of those shares trade freely on the stock exchange on any given day. A significant portion is often held by promoters, governments, or strategic investors who have no intention of selling in the near term. Free-float market capitalisation strips those locked-in shares out of the calculation and counts only the shares that are genuinely available for public trading. If a company has issued 100 shares in total but promoters hold 60, only the remaining 40 shares are considered the free float, and the index uses that smaller number when calculating the company's weight.

The practical consequence is that a company's weight in an index like the NIFTY 50 is determined by how large its freely tradeable market value is relative to the combined freely tradeable market value of all 50 companies in the index. A company with a very high total market cap but a small free float will have a lower index weight than its headline size might suggest, while a company with a large free float will have a proportionally bigger influence on daily index movements. This design is intended to make the index a more realistic reflection of the investable market, since it tracks only the portion of each company that investors can actually access when making decisions about their portfolios.
