Why is Selan Expl. Tech falling/rising?

As of 21-Aug, Selan Explorations Technology Ltd is currently priced at 560.25, reflecting a decrease of 1.8, or 0.32%. The stock has recently underperformed its sector by 0.96% and has experienced a trend reversal, falling after three consecutive days of gains. Although it opened with a gain of 3.15% today and reached an intraday high of Rs 579.75, the overall performance has been weak, with a significant drop in delivery volume by 37.85% against the 5-day average. Over the past week, the stock has gained 6.96%, but it has seen a substantial decline of 15.00% over the past month and a staggering 43.94% over the past year. The company's low debt-to-equity ratio and healthy long-term growth in operating profit contrast sharply with its recent flat quarterly results, which included a 37.1% fall in PAT and the lowest net sales recorded.
In the broader market context, while the Sensex has shown a modest gain of 1.74% over the past week, Selan's performance has been significantly worse, with a year-to-date decline of 31.96% compared to the Sensex's increase of 4.94%. The stock's valuation appears expensive with a Price to Book Value of 1.8, and the lack of domestic mutual fund investment may indicate a lack of confidence in the stock's current price. Despite a positive growth rate in profits, the stock's negative return over the past year, coupled with the broader market's relatively stable performance, suggests that investor sentiment remains cautious.
