Why is SMS Lifesciences falling/rising?

As of 23-Jul, SMS Lifesciences India Ltd is experiencing a decline in its stock price, currently at Rs 1,220.35, which reflects a decrease of 4.65 points or 0.38%. The stock has underperformed its sector by 0.89% today, reaching an intraday low of Rs 1,194, which is a drop of 2.53%. Over the past week, the stock has seen a significant decline of 6.07%, although it has performed positively over the last month with a return of 3.42%. Despite a strong annual return of 40.75%, the stock's recent performance is hindered by a notable drop in investor participation, with delivery volume plummeting by 91.1% compared to the 5-day average. While the stock has attractive valuations and a low PEG ratio, its long-term fundamentals are weak, as indicated by a declining profit after tax and low operating profit to interest ratio.
In the broader market context, the Sensex has shown a slight increase of 0.11% over the past week, contrasting with SMS Lifesciences' decline. The stock's year-to-date performance of 1.53% lags behind the Sensex's 5.87% gain, suggesting that while the company has historically outperformed the market, its recent struggles are more pronounced. The weak long-term growth indicators, including a low average return on capital employed and stagnant net sales growth, contribute to the stock's current downward trajectory, despite its previous strong performance relative to the market.
