Why is Popular Vehicles falling/rising?

As of 27-Jun, Popular Vehicles & Services Ltd is experiencing a decline in its stock price, currently at Rs 129.05, which represents a decrease of Rs 2.95 or 2.23%. The stock has underperformed its sector by 2.01% today and has fallen after three consecutive days of gains. It touched an intraday low of Rs 128.5. Over the past week, the stock has shown a positive return of 6.65%, but it has significantly underperformed over the last year with a return of -47.36%. Despite a healthy long-term growth in net sales and operating profit, the company has reported negative results for the last three consecutive quarters, leading to a negative return on equity and a high debt to EBITDA ratio, which negatively impacts investor sentiment.
In the broader market context, the Sensex has increased by 2.00% over the past week, indicating that while the stock has gained in the short term, it still lags behind the benchmark. The stock's year-to-date performance is notably poor at -16.74%, contrasting sharply with the Sensex's gain of 7.58% during the same period. This underperformance, coupled with the company's inability to service its debt and recent negative earnings reports, has contributed to a lack of investor confidence, resulting in the current downward price movement.
