Why is ONGC falling/rising?

As of 02-Sep, Oil & Natural Gas Corporation Ltd. is experiencing a slight increase in its stock price, currently at 239.45, reflecting a change of 0.75 or 0.31% upwards. The stock has shown a positive performance over the last three days, gaining 2.57%, although it underperformed its sector by 0.4% today. Despite being higher than the 5-day and 20-day moving averages, it remains below the longer-term moving averages. The stock's recent performance has been mixed, with a year-to-date return of 0.17%, but a significant decline of 26.62% over the past year. The company has a strong ability to service debt, a healthy long-term growth rate in net sales and operating profit, and a high dividend yield of 4.69%, which may contribute positively to investor sentiment.
In the broader market context, the stock has outperformed the benchmark Sensex over the past week and month, with returns of 2.26% and 1.10%, respectively, while the Sensex has declined. However, the stock's performance over the past year has been notably poor compared to the market, with a decline that is significantly greater than the benchmark's. This underperformance, combined with a recent drop in investor participation indicated by a 66.82% decrease in delivery volume, may raise concerns among investors. Despite these challenges, the stock's high institutional holdings at 37.23% suggest that more knowledgeable investors are backing the company, which could provide some stability amidst its recent volatility.
