Why is ONGC falling/rising?

As of 22-Aug, Oil & Natural Gas Corporation Ltd. (ONGC) is experiencing a decline in its stock price, currently at 236.30, reflecting a decrease of 1.95 points or 0.82%. The stock has fallen after two consecutive days of gains and is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, ONGC has seen a slight decline of 0.25%, while its performance over the past month shows a more significant drop of 4.10%. Despite these declines, there has been a rise in investor participation, with delivery volume increasing by 10.59% against the 5-day average. The company maintains a high dividend yield of 5.77%, and its strong ability to service debt is supported by a low Debt to EBITDA ratio of 1.41 times. However, the stock has generated a return of -27.10% over the past year, coinciding with a 20.9% fall in profits, which may contribute to investor caution.
In the broader market context, ONGC's short-term performance has lagged behind the benchmark Sensex, which has gained 0.88% over the past week. While ONGC's long-term growth prospects appear healthy, with net sales growing at an annual rate of 11.73%, the recent negative returns compared to the benchmark may be influencing investor sentiment. The stock's valuation remains attractive, trading at a discount relative to its peers, and it benefits from high institutional holdings at 37.23%. Nevertheless, the overall market environment and the stock's recent performance suggest that investors are currently cautious, leading to the observed decline in price.
