Why is Syrma SGS Tech. falling/rising?

As of 17-Sep, Syrma SGS Technology Ltd's stock price is currently at Rs 798.15, reflecting a decline of Rs 21.85 or 2.66%. The stock has underperformed its sector today by 2.87%, with an intraday low of Rs 791.4, indicating a significant drop of 3.49%. Over the past week, the stock has decreased by 5.76%, although it has shown a strong performance over the past month with a gain of 15.29%. Despite the recent decline, the company has demonstrated healthy long-term growth, with net sales increasing at an annual rate of 40.92% and operating profit at 42.30%. However, the falling investor participation, with a 14.73% drop in delivery volume against the 5-day average, may be contributing to the current price movement.
In the broader market context, the Sensex has increased by 1.56% over the past week, contrasting with Syrma's decline, which highlights the stock's underperformance relative to the benchmark. While the stock has generated impressive returns of 80.90% over the past year, its current valuation appears expensive, with a high enterprise value to capital employed ratio of 7.6. Additionally, despite the positive trend of increasing institutional investor participation, which has risen by 1.56% over the previous quarter, the stock's recent price drop suggests that market sentiment may be cautious, particularly in light of its high valuation metrics compared to peers.
