Why is Vishal Mega Mart falling/rising?

As of 30-Jul, Vishal Mega Mart Ltd's stock price is currently at Rs 137.90, reflecting an increase of Rs 1.3 or 0.95%. The stock has been gaining for the last two days, with a total return of 3.84% during this period. However, it has underperformed its sector by 5.65% today and is still 3.99% away from its 52-week high of Rs 143.4. The stock's recent performance shows a mixed picture; while it has a strong ability to service debt and healthy long-term growth in net sales and operating profit, there are concerns due to flat results in March and a significant decrease in promoter confidence, with promoters reducing their stake by 20.33%.
In the broader market context, Vishal Mega Mart's stock has underperformed the benchmark Sensex over the past week, with a decline of 2.13% compared to the Sensex's drop of 1.50%. However, it has outperformed the benchmark over the past month, gaining 2.99% while the Sensex fell by 2.54%. The retailing sector has seen a gain of 6.32%, indicating a favorable environment for the industry, which may support the stock's recent upward movement despite the concerns surrounding promoter confidence and valuation metrics.
