Why is BLS Internat. falling/rising?

As of 06-Aug, BLS International Services Ltd is experiencing a price increase, currently at 402.15, which reflects a change of 1.9 or 0.47% upward. The stock has shown strong performance recently, gaining 5.93% over the last three days and outperforming its sector by 0.69% today. It is also trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. The company has demonstrated healthy long-term growth, with operating profit increasing at an annual rate of 50.64%, and it has declared positive results for the last 17 consecutive quarters, including record net sales and profit figures in its latest quarterly report. However, there are concerns regarding its valuation, as it has a high Price to Book Value ratio of 9.6, and institutional investor participation has decreased slightly.
In the broader market context, BLS International's short-term performance has been notably strong, with a 6.69% increase over the past week, contrasting sharply with the Sensex, which has declined by 1.15% during the same period. While the stock has outperformed the benchmark in the short term, it has a year-to-date return of -16.71%, which is significantly below the Sensex's positive return of 3.08%. This divergence highlights the stock's recent recovery amidst broader market challenges, although the decline in institutional investor stakes may indicate caution among more experienced investors regarding its valuation and future growth potential.
