Why is National Plastic falling/rising?

As of 05-Sep, National Plastic Technologies Ltd is currently priced at 230.90, reflecting an increase of 2.4 (1.05%). The stock has shown a positive trend recently, gaining 3.2% over the last two days, although it opened with a loss of 3.28% today, reaching an intraday low of Rs 221. Despite the recent gains, the stock has underperformed in the longer term, with a year-to-date decline of 43.64% compared to a 3.29% increase in the benchmark. The company has demonstrated healthy long-term growth with net sales increasing at an annual rate of 36.24%, and while profits have risen by 8.5% over the past year, the stock's return of -40.02% indicates significant challenges, particularly a high Debt to EBITDA ratio of 3.72 times, which raises concerns about its ability to service debt.
In the broader market context, the stock's recent performance contrasts with the Sensex, which has gained 1.13% over the past week. While National Plastic has outperformed its sector by 0.88% today, its overall returns have lagged behind the market significantly over the past year. The stock's long-term performance remains strong, with a 201.63% increase over three years and a remarkable 664.57% rise over five years, but the recent volatility and substantial declines in the short term highlight the challenges it faces in the current market environment.
