Why is Marathon Nextgen falling/rising?

As of 28-Aug, Marathon Nextgen Realty Ltd is experiencing a price increase, with its current price at 636.70, reflecting a rise of 9.05 or 1.44%. Today's price summary indicates that the stock has outperformed its sector by 2.6% and has gained after three consecutive days of decline, reaching an intraday high of Rs 644.6. Despite this positive movement, the stock has seen a decrease of 2.38% over the past week and 3.38% over the past month, although it has generated an impressive 8.90% return year-to-date and 8.84% over the past year. The stock's long-term performance is notable, with a staggering 184.11% increase over the last three years, but it faces challenges such as weak long-term fundamental strength and a high Debt to EBITDA ratio.
In the broader market context, the stock's recent performance contrasts with the Sensex, which has declined by 2.34% over the past week and 1.00% over the past month. While Marathon Nextgen has shown resilience with positive returns year-to-date and over the past year, the weak long-term growth indicators and declining investor participation, as evidenced by a significant drop in delivery volume, raise concerns about its sustainability. The company’s high valuation relative to its fundamentals, alongside flat results in recent financials, suggests that while the stock is currently rising, there are underlying issues that could impact its future performance.
