Intraday Price Movement and Trading Activity
On the trading day, Reliance Infrastructure opened with a notable gap up of 5%, signalling strong demand from the outset. The stock touched an intraday high of ₹164.98, representing the upper price band limit of 5% for the day, before settling at the last traded price (LTP) of ₹162.0. The price range for the session was between ₹158.0 and ₹164.98, underscoring significant volatility within the permitted band.
Trading volumes were substantial, with total traded volume reaching approximately 14.92 lakh shares, generating a turnover of ₹24.28 crore. This level of liquidity indicates active participation from market participants, although delivery volumes showed a contrasting trend. The delivery volume on 17 Dec stood at 2.33 lakh shares, marking a decline of 12.06% compared to the five-day average, suggesting a reduction in investor commitment to holding shares beyond the trading day.
Performance Relative to Sector and Market Benchmarks
Reliance Infrastructure’s 1-day return of 3.10% outpaced the power sector’s decline of 0.89% and the Sensex’s marginal fall of 0.21%. This divergence highlights the stock’s relative strength amid a broadly subdued market environment. Over the past five trading sessions, the stock has recorded consecutive gains, accumulating a total return of 25.3%, a remarkable performance within the power sector.
Despite this short-term momentum, the stock’s price remains below its longer-term moving averages, including the 50-day, 100-day, and 200-day averages, while trading above the 5-day and 20-day averages. This technical positioning suggests that while recent buying interest has been strong, the stock has yet to fully recover from prior downward trends.

Upper Circuit Trigger and Regulatory Freeze
Reliance Infrastructure’s price movement triggered the upper circuit limit of ₹164.98, capping the maximum permissible gain at 5% for the day. This regulatory mechanism is designed to curb excessive volatility and speculative trading. Once the upper circuit is hit, trading in the stock is subject to a freeze, preventing further price advances during the session.
The upper circuit hit reflects intense buying pressure that outstripped available supply at lower price levels. However, the freeze also means that a portion of demand remains unfilled, as market participants are unable to transact beyond the price band. This unfulfilled demand often leads to a build-up of buy orders, which can influence subsequent trading sessions.
Market Capitalisation and Sector Context
Reliance Infrastructure is classified as a small-cap company with a market capitalisation of approximately ₹6,436 crore. Operating within the power industry, the company’s stock performance is closely watched by investors seeking exposure to the sector’s dynamics. The power sector has experienced mixed trends recently, with some stocks facing headwinds due to regulatory and operational challenges, while others have benefited from infrastructure investments and policy support.
In this context, Reliance Infrastructure’s recent price action stands out as a notable exception, demonstrating resilience and investor interest despite broader sector pressures.
Liquidity and Trading Size Considerations
Liquidity metrics indicate that Reliance Infrastructure is sufficiently liquid for moderate trade sizes. Based on 2% of the five-day average traded value, the stock can accommodate trade sizes of up to ₹0.46 crore without significant market impact. This level of liquidity is important for institutional investors and traders who require the ability to enter and exit positions efficiently.
However, the decline in delivery volumes suggests that some investors may be engaging in short-term trading strategies rather than long-term accumulation. This pattern can contribute to price volatility and may warrant close monitoring in the coming sessions.

Outlook and Investor Considerations
The recent surge in Reliance Infrastructure’s share price, culminating in the upper circuit hit, reflects a strong short-term buying interest. Investors should note that while the stock has outperformed its sector and the broader market in the last five days, it remains below key longer-term moving averages, indicating that the broader trend may still be under pressure.
Additionally, the regulatory freeze following the upper circuit hit means that some demand remains unmet, which could translate into further price movement in subsequent sessions if buying interest persists. Conversely, the decline in delivery volumes may signal caution among investors regarding sustained accumulation.
Given these mixed signals, market participants are advised to monitor trading volumes, price action relative to moving averages, and sector developments closely before making investment decisions.
Summary
Reliance Infrastructure’s stock performance on 18 Dec 2025 was marked by a strong rally that pushed the price to the upper circuit limit, supported by significant trading volumes and a notable gap up at the open. The stock outperformed its sector and the Sensex, reflecting robust investor interest despite a decline in delivery volumes and the imposition of a regulatory trading freeze. As a small-cap player in the power sector, Reliance Infrastructure’s price action warrants attention from investors seeking exposure to this segment, with careful consideration of liquidity and technical indicators.
