Why is Tulsyan NEC falling/rising?

As of 20-Jun, Tulsyan NEC Ltd's stock price is currently at Rs 41.78, reflecting an increase of Rs 2.09 or 5.27%. Today, the stock has shown a positive trend, gaining after four consecutive days of decline, and opened with a significant gap up of 9.85%. Despite this short-term gain, the stock has underperformed over the past week and month, with returns of -2.84% and -11.11%, respectively. The company has faced substantial challenges, including negative results for the last three quarters and a high Debt to EBITDA ratio, which raises concerns about its long-term viability. Additionally, 99.63% of promoter shares are pledged, which can exert downward pressure on the stock price in a declining market.
In the broader market context, while Tulsyan NEC's stock has risen today, it has significantly lagged behind the Sensex, which has gained 1.59% over the past week and 1.50% over the past month. The stock's year-to-date performance is particularly concerning, with a decline of 40.65% compared to the Sensex's increase of 5.46%. This stark contrast highlights the stock's ongoing struggles despite today's temporary rebound, indicating that investor sentiment remains cautious given the company's weak fundamentals and historical performance.
