Early Week Gains Supported by Bullish Technical Momentum

Union Bank of India began the week with a modest gain of 0.08% on 20 April, closing at Rs.189.05, marginally above the previous Friday’s close of Rs.188.90. This was accompanied by a shift in technical momentum from mildly bullish to bullish, supported by strong moving averages and bullish Bollinger Bands on daily and monthly charts. The stock’s price action near the upper trading range and positive monthly MACD and KST indicators suggested strengthening momentum despite mixed weekly signals.

On 21 April, the stock continued its upward trajectory, gaining 1.14% to close at Rs.191.20. This rally was underpinned by sustained buying interest and technical confirmation from daily moving averages, which remained firmly bullish. The Sensex also advanced 0.77% that day, but Union Bank outperformed the benchmark, reflecting relative strength within the public sector banking segment.

Intraday High and Outperformance on 22 April Amid Market Weakness

On 22 April, Union Bank of India surged 1.46% to close at Rs.194.00, hitting an intraday high of Rs.197. This represented a 3.06% intraday gain and marked the fourth consecutive day of positive returns. The stock outperformed both its sector and the broader market, which saw the Sensex decline by 0.23%. Technical indicators remained supportive, with the stock trading above all key moving averages and Bollinger Bands signalling bullish conditions. The proximity to the 52-week high of Rs.205.45 underscored the stock’s strong price foundation.

Sharp Reversal and Heavy Selling Pressure on 23 April

The stock’s momentum reversed dramatically on 23 April, with Union Bank of India plunging 7.40% to close at Rs.179.65. Intraday, the share price touched a low of Rs.177.60, marking an 8.62% drop from the previous close. This sharp decline followed four consecutive days of gains and was accompanied by exceptionally high trading volumes exceeding 5.1 crore shares by value and 3.87 crore shares by volume, signalling intense investor activity.

Put option activity surged on this day, with 9,578 contracts traded at the 180 strike price expiring on 28 April, reflecting increased bearish sentiment and hedging. The weighted average price of these options clustered near the day’s low, reinforcing the cautious outlook. Despite the price drop, the stock remained above its 100-day and 200-day moving averages, indicating longer-term support, but it slipped below shorter-term averages, signalling immediate weakness.

This sell-off was sharper than the public sector banking sector’s 2.06% decline and the Sensex’s 0.78% fall, highlighting stock-specific pressures likely driven by profit-booking and technical corrections. The Mojo Score remained at 78.0 with a Buy rating, downgraded from Strong Buy in March, reflecting a tempered but still positive medium-term outlook.

Continued Price Pressure and Elevated Volumes on 24 April

On 24 April, Union Bank of India’s shares declined a further 1.48% to close at Rs.177.00, with trading volumes remaining elevated at over 74.5 lakh shares. The stock underperformed both its sector and the Sensex, which fell by 0.46% and 0.71% respectively. Delivery volumes surged by 218.26% compared to the five-day average, suggesting significant institutional participation, possibly reflecting distribution amid price weakness.

Technical momentum softened from bullish to mildly bullish, with mixed signals from MACD, KST, and RSI indicators across weekly and monthly timeframes. While longer-term monthly indicators remained positive, weekly and daily charts showed caution, indicating a consolidation phase after the recent correction. The stock’s valuation metrics improved, with P/E and P/BV ratios moving into the 'very attractive' category, signalling a potential value opportunity despite near-term volatility.

Key Takeaways: Strengths and Cautionary Signals

Positive Factors: Union Bank of India demonstrated strong technical momentum early in the week, with price gains supported by bullish moving averages and Bollinger Bands. The stock’s proximity to its 52-week high and robust long-term returns—448.55% over five years versus Sensex’s 62.21%—highlight its resilience. Valuation metrics have improved, with P/E at 7.06 and P/BV at 1.09, placing the stock in the 'very attractive' category relative to peers. Delivery volumes surged, indicating active institutional participation.

Cautionary Signals: The sharp 7.40% drop on 23 April amid heavy volumes and put option activity signals increased bearish sentiment and profit-taking. The stock slipped below short-term moving averages, reflecting immediate technical weakness. The downgrade from Strong Buy to Buy by MarketsMOJO and mixed momentum indicators suggest a consolidation phase with potential volatility ahead. Elevated delivery volumes amid price declines may indicate distribution rather than accumulation, warranting close monitoring.

Conclusion: Navigating a Volatile Phase Amid Strong Fundamentals

Union Bank of India’s week was marked by a strong start with bullish technical momentum, followed by a sharp correction driven by profit-booking, heavy trading volumes, and increased bearish positioning in options markets. Despite the near-term weakness and volatility, the stock’s long-term performance, improved valuation, and large-cap status provide a solid fundamental base. Investors should watch key support levels near Rs.177 and resistance around the 52-week high of Rs.205.45, while monitoring volume trends and technical signals for indications of stabilisation or further downside. The current environment calls for a balanced approach, recognising both the risks of short-term price pressure and the opportunities presented by attractive valuation metrics.
