Why is BLB falling/rising?

As of 23-Sep, BLB Ltd's stock price is currently at 15.57, reflecting a slight increase of 0.04 or 0.26%. The stock has shown a trend reversal, gaining after three consecutive days of decline. However, it has underperformed in the longer term, with a year-to-date return of -21.72% and a one-year return of -24.01%. The stock's performance today is in line with the sector, but there is a notable decline in investor participation, as the delivery volume has fallen by 39.49% compared to the five-day average. Despite a relatively attractive valuation with a Price to Book Value of 0.8 and a Return on Equity of 6.8, the stock's profits have decreased by 26.3% over the past year, indicating underlying weaknesses.
In the broader market context, the Sensex has shown a positive return of 5.07% year-to-date, contrasting sharply with BLB Ltd's negative performance. Over the past week, while the stock remained flat at 0.00%, the benchmark has declined by 0.34%. This consistent underperformance against the benchmark over the last three years, along with weak long-term fundamental strength and declining net sales, suggests that the stock is struggling to attract investor confidence, which may contribute to its recent price movements.
