Why is Petro Carbon falling/rising?

As of 11-Aug, Petro Carbon & Chemicals Ltd is experiencing a price increase, with its current price at 175.45, reflecting a change of 2.55 or 1.47% upward. Despite this positive movement today, the stock has been underperforming in the longer term, with a year-to-date decline of 16.77% and a significant drop of 37.68% over the past year. Additionally, the stock is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish trend. Furthermore, there has been a notable decrease in investor participation, with delivery volume falling by 33.33% compared to the 5-day average, which may suggest waning interest among investors.
In the broader market context, Petro Carbon's short-term performance has outperformed the Sensex by 0.64% today, although it has still seen a slight decline of 0.31% over the past week compared to the benchmark's 0.56% drop. This indicates that while the stock is rising today, its overall performance remains weak relative to the market. The year-to-date and yearly returns further highlight the challenges faced by Petro Carbon, contrasting sharply with the Sensex's positive performance of 3.98% year-to-date and 0.89% over the past year.
