Why is Simm. Marshall falling/rising?

As of 07-Jul, Simmonds Marshall Ltd is currently priced at 140.00, reflecting a decrease of 5.5, or 3.78%. The stock has been underperforming, having fallen for the last two days with a total decline of 4.34%. Despite opening with a gain of 2.37% today and reaching an intraday high of Rs 149.25, it also touched a low of Rs 139. The stock has shown strong performance over the past week and month, with returns of 7.44% and 12.49%, respectively. However, year-to-date, it is down 6.67%. The company has consistently reported positive results over the last nine quarters, with significant growth in profit before tax and profit after tax, indicating strong fundamentals that may support its valuation despite the recent price decline.
In the broader market context, the Sensex has seen a slight decline of 0.20% over the past week, while the fasteners sector, in which Simmonds Marshall operates, has fallen by 2.1%. This suggests that the stock's recent decline may be influenced by sector-specific challenges rather than company-specific issues. Additionally, while the stock has outperformed the benchmark over the past year with a return of 28.32% compared to the Sensex's 4.31%, its year-to-date performance indicates a divergence from this trend. The stock's attractive valuation, as indicated by its low PEG ratio and strong return on capital employed, suggests that it may be a hold for investors despite the recent price movement.
