Why is Simplex Castings falling/rising?

As of 18-Jul, Simplex Castings Ltd is currently priced at 381.25, reflecting a decrease of 7.75, or 1.99%. The stock has recently underperformed its sector by 1.18% and has experienced a trend reversal, falling after three consecutive days of gains. Despite this short-term decline, the stock has shown strong performance over longer periods, with a 1-month return of 19.97% and a year-to-date return of 21.01%. The company has reported significant growth in net profit and sales, with a 184.92% increase in net profit and a record net sales figure of Rs 67.10 crore. However, the recent drop in delivery volume by 83.22% against the 5-day average indicates a decrease in investor participation, which may be contributing to the current price decline.
In the broader market context, the stock's 1-week return of -1.69% contrasts with the Sensex's decline of only 0.90%, suggesting that the stock is underperforming relative to the overall market. While Simplex Castings has consistently outperformed the BSE500 over the past three years, the recent price movement may reflect a temporary correction after a period of strong gains. The stock's valuation remains fair, trading at a discount compared to peers, and its robust historical performance indicates potential for recovery. However, the combination of decreased investor participation and the recent price drop may be causing short-term volatility despite the company's strong fundamentals.
