Why is SMS Lifesciences falling/rising?

As of 17-Sep, SMS Lifesciences India Ltd is experiencing a decline in its stock price, currently at 1,205.00, reflecting a decrease of 5.2 points or 0.43%. The stock has underperformed its sector by 0.47% today and has seen a trend reversal after two consecutive days of gains. Despite a positive performance over the past week and month, with returns of 4.78% and 11.46% respectively, the stock has a troubling one-year return of -22.18%. The company's return on capital employed (ROCE) stands at 10.7, indicating an attractive valuation relative to its peers, but the stock's profits have decreased by 3.4% over the past year, contributing to its recent price movement.
In the broader market context, while the Sensex has gained 1.56% over the past week and 2.60% over the past month, SMS Lifesciences' recent performance indicates a significant underperformance compared to the market, particularly over the last year where it has fallen more sharply than the BSE500's -2.63%. The stock's liquidity appears sufficient for trading, but the weak long-term fundamentals, including a poor growth rate in net sales and operating profit over the past five years, suggest ongoing challenges that may be influencing investor sentiment negatively.
