Why is I O B falling/rising?

As of 10-Sep, Indian Overseas Bank's stock price is currently at 39.56, reflecting an increase of 0.62 or 1.59%. The stock has been gaining for the last four days, with a total return of 4.24% during this period. However, it has underperformed its sector by 0.34%. In terms of longer-term performance, the stock has shown a 10.47% increase over the past month, but it remains down 23.41% year-to-date and 32.05% over the past year. The stock's moving averages indicate that it is performing better than the 5-day, 20-day, 50-day, and 100-day averages, but it is still below the 200-day moving average. Additionally, there has been a significant decline in investor participation, with delivery volume dropping by 58.44% compared to the 5-day average.
In the broader market context, the stock's short-term return of 10.47% over the past month is notably lower than the Sensex's return of 1.96% during the same period. Despite this, the bank's strong lending practices, evidenced by a low Gross NPA ratio of 1.97% and consistent net profit growth at a CAGR of 19.82%, contribute positively to its long-term fundamentals. The company has reported positive results for the last 22 consecutive quarters, which supports its stability. However, the falling investor participation may indicate a lack of confidence or interest in the stock, which could be affecting its price movement in the short term.
