Why is Nectar Lifesci. falling/rising?

As of 10-Jul, Nectar Lifescience Ltd's stock price is currently at Rs 19.47, reflecting an increase of Rs 3.0 or 18.21%. Today, the stock has shown a positive performance, outperforming its sector by 18.78% and reversing a two-day decline. It opened with a gain of 2.31% and reached an intraday high of Rs 19.76, although it also experienced significant volatility, trading within a wide range of Rs 3.62. Despite this short-term gain, the stock has underperformed over longer periods, with a year-to-date decline of 50.08% and a one-year return of -34.97%. The company's financial health is concerning, characterized by operating losses, a high debt-to-EBITDA ratio of 7.73, and a negative return on equity, which collectively indicate weak long-term fundamental strength.
In the broader market context, while Nectar Lifescience's stock has risen today, it has significantly lagged behind the benchmark Sensex, which has gained 6.46% year-to-date. The stock's recent performance is overshadowed by its long-term underperformance, as it has generated negative returns over the past year and three years compared to the broader market. Additionally, the high percentage of pledged promoter shares adds to the risk, potentially exerting downward pressure on the stock in a falling market. Overall, while today's price movement shows a temporary rise, the underlying financial challenges and poor historical performance suggest a cautious outlook for investors.
