Stock Market Outlook Today, August 22

Despite the initial weakness, the bulls defended key support levels, triggering a sharp intraday rebound that pushed the Nifty to the day's high within an hour. Following the recovery, the index remained largely range-bound, hovering around the 25,100 mark.

On the weekly expiry day, the Nifty continued its bullish streak for the sixth consecutive session, led by strength in pharma stocks such as Cipla and Dr. Reddy's, along with financial major Bajaj Finserv. However, some stocks like Tata Consumer, Bajaj Auto, and Eternal weighed down on the index, ending as the top laggards.

Sectorally, Nifty Pharma, Healthcare, and Realty emerged as the top performers, indicating a shift in focus toward defensive and rate-sensitive sectors. On the flip side, FMCG, PSU Bank, and Auto stocks came under pressure, reflecting ongoing sectoral rotation in the market.

Sensex, Nifty Prediction Today for August 22, 2025

The Sensex and Nifty outlook for August 22 suggests a continued positive bias, particularly as long as the Nifty holds above the crucial 25,000 mark. The index is expected to trade within a range of 24,800 to 25,300, with key support levels placed at 24,900 and 24,800, while resistance is likely to be encountered around 25,200 to 25,300.

Based on options data, the broader trading range is projected between 24,600 and 25,600, indicating room for both consolidation and upward movement. Market sentiment remains constructive, and a sustained move above 25,000 could lead to a breakout towards 25,300, keeping the bulls in control.

According to Chandan Taparia of Motilal Oswal, the market maintains a positive bias as long as Nifty sustains above the 25,000 mark. If this level holds, the momentum is likely to carry the index towards the 25,200 to 25,300 zone in the near term. On the downside, support levels are shifting higher, with the next base placed around 24,900 and 24,800.

Technically, the weekly chart has shown an inside-bar breakout, while the daily chart reflects a series of higher highs and higher lows over the last six sessions, a clear indicator of ongoing bullish strength. The recent gap-up opening, driven by optimism surrounding GST reforms, has further supported the market's uptrend this week.
