Why is SP Refractories falling/rising?

As of 22-Sep, SP Refractories Ltd is currently priced at 108.30, with no change in price (0.00%). The stock has been underperforming recently, with a significant decline of 26.33% over the past month and a year-to-date drop of 38.06%. Although today's performance shows that it has outperformed its sector by 2.51%, it is trading lower than all key moving averages, indicating a bearish trend. Additionally, there has been a notable increase in investor participation, with delivery volume rising by 114.29% against the 5-day average, suggesting some renewed interest despite the overall downward trajectory.
In the broader market context, SP Refractories' recent performance contrasts sharply with the Sensex, which has gained 1.34% over the past month. This indicates that while the stock is struggling, the overall market is experiencing modest growth. The stark difference in returns, particularly the stock's 1-year decline of 43.89% compared to the Sensex's slight decrease of 2.28%, highlights the challenges SP Refractories faces in attracting investor confidence amidst a generally stable market environment.
