Why is Spel Semiconduct falling/rising?

As of 03-Sep, Spel Semiconductor Ltd's stock price is currently at Rs 188.10, reflecting a significant increase of 31.35, or 20.0%. The stock has been on a positive trajectory, gaining 49.4% over the last four days and outperforming its sector by 18.35% today. It opened with an 8.45% gain and reached an intraday high of Rs 188.1. Over the past week, the stock has surged by 48.11%, and in the last month, it has increased by 60.56%. However, despite this recent performance, the company faces challenges such as operating losses, a high Debt to EBITDA ratio of 4.25 times, and a low average Return on Equity of 3.66%, indicating weak long-term fundamental strength and profitability concerns.
Broader market context shows that while Spel Semiconductor has experienced substantial short-term gains, the benchmark Sensex has seen a slight decline of 0.27% over the past week. This stark contrast highlights the stock's strong performance relative to the broader market. However, the company’s weak fundamentals, including negative EBITDA and a significant drop in profits over the past year, suggest that the current price movement may not be sustainable in the long term. Additionally, the minimal stake held by domestic mutual funds could indicate a lack of confidence in the company's future prospects, further complicating the outlook despite the recent price rise.
