Why is Sati Poly falling/rising?

As of 18-Sep, Sati Poly Plast Ltd's stock price is currently at 64.30, reflecting a decrease of 3.35, or 4.95%. The stock has significantly underperformed, with a one-week return of -12.28% and a one-month return of -20.52%. Additionally, it has shown a year-to-date decline of 66.68% and a one-year decline of 68.63%. Today's price summary indicates that Sati Poly is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, suggesting a bearish trend. However, there has been a notable increase in investor participation, with delivery volume rising by 49.35% compared to the 5-day average, which may indicate some interest despite the overall negative performance. There is no information available regarding positive or negative factors that could further explain the stock's recent movement.
In the broader market context, Sati Poly's performance has been starkly contrasted by the Sensex, which has gained 1.67% over the past week and 2.20% over the past month. This disparity highlights the stock's struggles relative to the benchmark, particularly as it has not only underperformed in the short term but also significantly lagged behind the market on a year-to-date basis. The overall liquidity of the stock remains adequate for trading, but the persistent decline in its price suggests that investor sentiment is currently negative, further exacerbated by its poor returns compared to the broader market.
