Why is Nureca falling/rising?

As of 19-Sep, Nureca Ltd's stock price is currently at Rs 255.55, reflecting an increase of Rs 5.25 or 2.1%. The stock has shown a trend reversal by gaining after three consecutive days of decline and has outperformed its sector by 4.29%. Despite this positive movement today, the stock has had a challenging performance over the longer term, with a year-to-date decline of 9.36% and a significant drop of 31.05% over the past year. While the company reported positive results in its latest quarter, with a higher profit after tax and record net sales, it also faces serious concerns such as a negative EBITDA and a long-term decline in net sales and operating profit.
In the broader market context, the Sensex has increased by 0.88% over the past week, while Nureca's stock has decreased by 0.25% in the same period, indicating underperformance relative to the benchmark. The stock's liquidity appears adequate for trading, but there has been a notable decline in investor participation, particularly among institutional investors, who have reduced their stakes. This lack of confidence from institutional investors, coupled with the company's consistent underperformance against the benchmark over the last three years, suggests that while there may be short-term gains, the long-term outlook remains precarious.
