Why is New India Assura falling/rising?

As of 07-Aug, New India Assurance Company Ltd's stock price is currently at Rs 194.80, reflecting an increase of Rs 4.35, or 2.28%. The stock has shown a mixed performance recently, with a 1-week decline of 2.96% and a 1-month increase of 3.95%. Today's trading saw the stock reach an intraday high of Rs 195.5, indicating positive momentum, although it also experienced a low of Rs 185.8. The stock's performance today outperformed its sector by 2.06%. However, there has been a notable decline in investor participation, with delivery volume dropping by 32.81% compared to the 5-day average, which may indicate waning interest despite the current price increase. Unfortunately, there is no information available regarding positive or negative factors affecting the stock.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has decreased by 0.69% over the past week while New India Assurance has declined by a greater margin. Year-to-date, the stock has underperformed the Sensex, which has gained 3.18%, while New India Assurance has fallen by 3.08%. This suggests that while the stock is experiencing a short-term rise, its overall performance remains weak compared to the market, particularly over longer periods such as the past year, where it has declined by 25.97% against the Sensex's modest gain of 1.45%.
