Why is Retina Paints falling/rising?

As of 18-Sep, Retina Paints Ltd's stock price is currently at Rs 73.00, reflecting an increase of Rs 1.9, or 2.67%. The stock has shown a positive performance today, outperforming its sector by 2.91% and opening with a gain of 2.53%. It reached an intraday high of Rs 73, indicating strong upward momentum. Additionally, the stock has traded in a narrow range of Rs 0.1, and there has been a significant increase in investor participation, with delivery volume rising by 706.45% compared to the 5-day average. However, the stock's longer-term performance has been less favorable, with a decline of 7.07% over the past month and 6.41% over the past year, while the benchmark Sensex has shown positive returns during these periods.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has gained 1.80% over the past week and 2.14% over the past month. This suggests that while Retina Paints is experiencing a short-term rally, it has underperformed the market in the longer term, as evidenced by its year-to-date return of -0.48% compared to the Sensex's 6.24%. The overall market sentiment appears to be more favorable for the benchmark, which may indicate that the recent rise in Retina Paints' stock price is driven by specific factors rather than a broader market trend.
