Why is Shaily Engineer. falling/rising?

As of 30-Jun, Shaily Engineering Plastics Ltd is experiencing a decline in its stock price, currently at Rs 1,662.50, reflecting a decrease of Rs 30.6 or 1.81%. The stock has underperformed its sector by 2.48% today, having touched an intraday low of Rs 1,658.3. Over the past week, the stock has decreased by 3.80%, and in the last month, it has fallen by 17.61%. Despite a strong long-term performance with a 107.28% increase over the past year, the stock's recent movement is influenced by its higher trading volatility, as indicated by its moving averages being lower than the 5-day, 20-day, 50-day, and 100-day averages. Additionally, while the company has demonstrated strong fundamentals, including a low Debt to EBITDA ratio and consistent operating profit growth, the stock is facing pressure due to its high valuation metrics and a relatively expensive PEG ratio of 1.3.
In the broader market context, the stock's recent performance contrasts sharply with the benchmark, as the Sensex has gained 2.09% over the past week and 2.65% over the past month. This divergence highlights the stock's struggles despite its impressive long-term returns, which significantly outpace the market's overall performance. The increase in institutional holdings suggests confidence in the company's fundamentals, yet the current market sentiment appears cautious, possibly due to the stock's high valuation relative to its earnings growth. This combination of factors contributes to the stock's downward movement in the short term, despite its strong historical performance.
