Why is Sanathan Textile falling/rising?

As of 24-Sep, Sanathan Textiles Ltd is currently priced at 513.95, reflecting a decrease of 0.8, or 0.16%. The stock has experienced a trend reversal, falling after two consecutive days of gains. Over the past week, it has underperformed the benchmark Sensex, with a return of -3.39% compared to the Sensex's -1.18%. However, on a monthly basis, the stock has shown a slight increase of 0.26%, while year-to-date, it has significantly outperformed the benchmark with a return of 40.31% against the Sensex's 4.58%. The stock's liquidity appears adequate, and there has been a notable rise in investor participation, with delivery volume increasing by 1822.82% against the 5-day average. The company maintains a low debt-to-equity ratio of 0.06 and an attractive valuation with a return on equity of 9.5, which may support its price stability despite the recent decline.
In the broader market context, the stock's recent performance contrasts with the benchmark's short-term returns, as it has declined more sharply than the Sensex over the past week. The increase in institutional investor participation, with a 0.52% rise in their stake, suggests a positive outlook from more sophisticated investors, which could provide some support for the stock. Despite the current price drop, the overall year-to-date performance remains strong, indicating that while there may be short-term volatility, the long-term fundamentals appear solid.
