Why is SEPC falling/rising?

As of 17-Sep, SEPC Ltd's stock price is currently at 12.13, reflecting a decrease of 0.02, or 0.16%. The stock has underperformed its sector by 0.53% today, following a trend reversal after two consecutive days of gains. Despite a positive growth in net sales of 71.71% and strong quarterly results, the stock has shown a significant decline of 62.68% over the past year. Additionally, the company has a high debt to EBITDA ratio and low return on equity, indicating weak long-term fundamental strength. The pledged promoter shares, which account for 33.95%, may also contribute to downward pressure on the stock price in a falling market.
In the broader market context, SEPC Ltd has outperformed the Sensex over the past week and month, with returns of 2.36% and 8.50%, respectively, compared to the Sensex's 1.56% and 2.60%. However, the stock's year-to-date performance remains poor at -42.89%, contrasting sharply with the Sensex's positive return of 5.83%. This disparity highlights the stock's underperformance relative to the broader market, particularly in the long term, where it has lagged behind both the BSE500 and its peers.
