Sensex And Nifty Extend Winning Streak To Fourth Day As GST Optimism And Rating Upgrade Lift Market Mood

The Indian stock market continued its upward momentum for the fourth consecutive session on Tuesday, August 19, 2025, buoyed by a mix of domestic policy optimism and global cues. Benchmark indices Sensex and Nifty 50 closed higher, supported by strong buying in auto, oil and gas, FMCG, and infrastructure stocks. Investor sentiment was lifted by expectations of Goods and Services Tax (GST) rationalisation and a recent upgrade in India’s sovereign credit rating by S&P Global. The rally also coincided with easing geopolitical tensions and a steady flow of institutional buying.

Policy Signals And Economic Drivers

Investor enthusiasm was largely driven by positive developments on the policy front:

- Prime Minister Narendra Modi’s announcement on GST rationalisation sparked hopes of tax simplification and improved corporate margins
- S&P Global’s upgrade of India’s credit rating added credibility to the country’s macroeconomic stability
- Hopes of a diplomatic breakthrough in the Russia–Ukraine conflict further eased global risk sentiment

Broader Market Trends And Group Movements

Technical Indicators And Resistance Levels

From a technical standpoint, Nifty remains sandwiched between key moving averages:

- The 20-day SMA at 24,740 acts as near-term support
- The 50-day SMA at 25,020 is a critical resistance level
- A decisive close above 25,020 could open the path toward 25,180–25,250
- Failure to hold above this band may trigger a pullback toward 24,600

Conclusion: Momentum Builds But Eyes On Earnings

The fourth straight day of gains reflects growing investor confidence, supported by policy clarity and macro stability. However, analysts caution that sustained momentum will depend on corporate earnings revival and global market cues. With GST reforms and geopolitical developments in focus, the coming sessions will be crucial in determining whether this rally has legs or pauses for breath.
