Why is HCP Plastene falling/rising?

As of 17-Nov, HCP Plastene Bulkpack Ltd is experiencing a decline in its stock price, currently at Rs 178.10, which reflects a decrease of Rs 9.35 or 4.99%. The stock has been underperforming, having fallen consecutively for the last two days with a total return of -9.73% during this period. Although the stock reached an intraday high of Rs 192.15, it has traded closer to its low price, indicating weak investor sentiment. Furthermore, the delivery volume has significantly decreased by 66.17% compared to the 5-day average, suggesting a drop in investor participation. Despite its strong long-term performance, with a 5-year return of 2726.98%, the recent trends indicate negative momentum.
Broader Market Context: In the short term, HCP Plastene's performance has been notably better than the benchmark Sensex, with a 1-week return of +9.26% compared to the Sensex's +1.69%. However, the stock's current decline contrasts with its positive year-to-date return of 16.41%, which is significantly higher than the Sensex's 8.72%. This suggests that while the stock has shown resilience over a longer period, recent trading activity and reduced investor engagement are contributing to its current downward trajectory.
