### The Trade Deal's Impact and Budget Day Echoes
The Indian equity market experienced a significant uplift following the announcement of an India-US trade deal on February 3, 2026. This agreement included a reduction in US tariffs on Indian goods from 50% to 18%, a move widely expected to bolster export competitiveness for Indian manufacturers [13, 29]. The immediate market reaction saw the Nifty 50 index surge, closing around 25,728 [29]. This positive sentiment appeared to overshadow initial reactions to the Union Budget presented on February 1, 2026, which had reportedly led to a sharp negative reaction including a dip in the Nifty 50 to 24,825.45 due to an increase in Securities Transaction Tax on derivatives [35]. The subsequent rally indicates the trade deal's substantial influence on investor confidence.
### Valuation Premium and Divergent Performance
Despite the recent positive momentum, the Nifty 50 is trading at a valuation premium, with a Price-to-Earnings (P/E) ratio hovering between 22.4 and 25 [7, 18]. This compares to the MSCI Emerging Markets index's P/E of approximately 17, suggesting that current market multiples may be stretched [18]. While the Nifty 50 exhibits resilience, the broader market indices show a more divergent performance. The Nifty MidCap 100 index is trading around 59,307 [2, 3, 4], and the Nifty SmallCap 100 index is at approximately 16,989 [5, 31]. Historically, Indian equities lagged global peers in 2025, with small and mid-cap segments facing headwinds from foreign portfolio investor (FPI) outflows and liquidity pressures, despite growing interest from domestic investors [14, 17, 27]. This underlying caution within smaller capitalization stocks contrasts with the Nifty's recent gains.
Sectorally, the market's positive response was broad-based, with realty, infrastructure, and energy sectors showing strength, while the information technology (IT) sector experienced underperformance relative to the wider market [29].
### Analyst Outlook and Technical Levels
Kunal Shah, Senior Technical Analyst at Mirae Asset ShareKhan, has outlined key technical levels to monitor for the Indian indices. For the Nifty 50, the 25,440 level, which was the Budget Day high, has now shifted to a crucial support floor [News1]. Immediate resistance is noted in the 25,900–26,000 zone, with a decisive breakout potentially propelling the index towards 26,500–26,700 [News1].
The Nifty MidCap 100 faces an immediate hurdle at 60,450. A sustained move above this level would signal a bullish shift, though consolidation is anticipated within the 58,600–60,450 range in the near term [News1]. The Nifty SmallCap 100, reflecting a more cautious undertone, has immediate upside hurdles at 17,500 and 18,000, with a critical support level at 16,200, below which the index could test the 15,000 psychological level [News1]. Investors are watchful for whether the current rally's breadth expands or remains concentrated, particularly given the premium valuations and the ongoing divergence between large-cap strength and mid/small-cap caution.
