Why is Selan Expl. Tech falling/rising?

As of 04-Sep, Selan Explorations Technology Ltd is experiencing a decline in its stock price, currently at Rs 551.00, which reflects a decrease of Rs 18.05 or 3.17%. Today's price summary indicates that the stock has underperformed its sector by 2.17%, reaching an intraday low of Rs 551. The stock's performance over the past week shows a positive return of 4.83%, but it has underperformed over the past month with a decline of 5.72%. The company has a low debt-to-equity ratio and has shown healthy long-term growth with an annual operating profit increase of 48.30%. However, recent financial results have been disappointing, with net sales falling by 20.22% and profit after tax declining by 37.1%. The stock is trading at a premium compared to its peers, which may contribute to investor hesitation.
Broader market context reveals that while the Sensex has shown a slight increase of 0.80% over the past week, Selan's stock has significantly underperformed the broader market, with a year-to-date decline of 33.09% compared to the Sensex's gain of 3.30%. The stock's performance over the last year is particularly concerning, with a drop of 44.84%, indicating a lack of confidence among investors, as evidenced by the negligible stake held by domestic mutual funds. This broader context of underperformance, combined with the company's recent financial setbacks, suggests that investors are cautious, leading to the current decline in stock price.
