Why is ONGC falling/rising?

As of 12-Sep, Oil & Natural Gas Corporation Ltd. is experiencing a decline in its stock price, currently at 233.30, reflecting a decrease of 0.35 (-0.15%). The stock has underperformed its sector by 0.63% today and has fallen after two consecutive days of gains. In the past week, the stock has decreased by 0.36%, and over the past month, it has dropped by 0.93%. Despite a high dividend yield of 5.35% and strong fundamentals such as a low Debt to EBITDA ratio and healthy long-term growth in net sales and operating profit, the stock has faced significant challenges, including a 20.65% decline over the past year, which is much steeper than the broader market's decline of 1.28%. In the broader market context, the Sensex has shown a positive return of 1.48% over the past week and 2.08% over the past month, indicating a strong market performance compared to ONGC's recent struggles. The stock's performance has been hindered by flat results reported in June and a significant underperformance relative to the market over the last year, which has likely affected investor sentiment. Additionally, while there is rising investor participation indicated by increased delivery volume, the overall trend and recent price movements suggest a cautious outlook for the stock amidst a recovering market.
