Why is RRP Defense falling/rising?

As of 04-Sep, RRP Defense Ltd's stock price is currently at Rs 420.80, reflecting an increase of Rs 8.25 or 2.0%. The stock has reached a new 52-week and all-time high today, having outperformed its sector by 1.6%. It has demonstrated a remarkable performance over the past week with a return of 10.37% and an impressive 51.34% over the last month. However, despite these gains, the company faces significant challenges, including operating losses and weak long-term fundamentals, as evidenced by a decline in net sales and a poor EBIT to interest ratio. Additionally, promoter confidence appears to be waning, with a decrease in their stake in the company, which may negatively impact investor sentiment.
Broader Market Context: In comparison to the broader market, represented by the Sensex, RRP Defense has significantly outperformed, with a year-to-date return of 2074.68% against the Sensex's 3.30%. Despite the stock's strong short-term performance, the overall market has generated negative returns over the past year, highlighting the stock's ability to thrive in a challenging environment. However, the broader market context also reveals that while the stock has surged, its fundamentals remain concerning, which could lead to volatility in future performance as investor participation has notably decreased.
