Why is Blue Star falling/rising?

As of 07-Jul, Blue Star Ltd. is currently priced at 1,814.90, reflecting a decrease of 25.2 points or 1.37%. The stock has been underperforming, having fallen consecutively for the last two days, with a total decline of 1.45% during this period. Today's trading saw the stock reach an intraday low of Rs 1802.35, indicating a drop of 2.05%. Despite a strong performance over the past week and month, with returns of 10.87% and 14.11% respectively, the stock has underperformed its sector by 1.07%. Additionally, the stock's delivery volume has decreased significantly, falling by 30.05% against the 5-day average, which may indicate waning investor interest. However, the company maintains a low debt profile and has demonstrated strong long-term fundamentals, including consistent positive results over the last 17 quarters and a healthy growth rate in operating profit.
In the broader market context, Blue Star's recent performance contrasts with the Sensex, which has experienced a slight decline of 0.20% over the past week. While Blue Star has shown strong returns over longer periods, including a 314.41% increase over the last three years, its year-to-date performance is notably weaker, with a decline of 14.69% compared to the Sensex's gain of 6.79%. This divergence suggests that while the company has solid fundamentals and institutional backing, current market sentiment may be affecting its short-term price movements negatively.
