Why is HCP Plastene falling/rising?

As of 28-Jul, HCP Plastene Bulkpack Ltd's stock price is currently at 188.00, reflecting a decrease of 6.15, or 3.17%. The stock has been underperforming recently, having fallen consecutively for the last three days, resulting in a total decline of 12.56% during this period. Today's trading saw the stock open with a loss of 5% and reach an intraday low of Rs 184.45, while the weighted average price indicates that more volume was traded closer to this low. In terms of returns, the stock has experienced a 3.76% decline over the past week, although it has shown a positive return of 9.30% over the past month. Despite strong management efficiency and significant profit growth in recent quarters, the stock's long-term performance has been hampered by high debt levels and poor growth in net sales and operating profit over the last five years.
In the broader market context, HCP Plastene's recent performance contrasts with the Sensex, which has declined by 1.59% over the past week. While the stock has outperformed the benchmark with a 9.30% increase over the last month compared to the Sensex's 3.77% decline, the current downward trend raises concerns among investors. The packaging sector, in which HCP operates, has also seen a decline of 2.71%, further contributing to the stock's struggles. Additionally, a significant drop in investor participation, with delivery volume falling by 91.25% against the five-day average, suggests waning interest, which could be influencing the stock's price movement negatively.
