Why is Spel Semiconduct falling/rising?

As of 08-Sep, Spel Semiconductor Ltd's stock price is rising, currently at 250.30, reflecting an increase of 22.75 or 10.0%. The stock has recently hit a new 52-week high and has been on a strong upward trend, gaining 98.81% over the last seven days. It has outperformed its sector by 8.8% today and is trading above all key moving averages. Despite these positive indicators, the company faces challenges such as operating losses and a high Debt to EBITDA ratio of 4.25 times, which raises concerns about its long-term fundamental strength. Additionally, while the stock has generated a 29.39% return over the past year, its profits have declined by 16%, indicating potential risks for investors.
In the broader market context, Spel Semiconductor's short-term performance significantly outpaces the benchmark, with a 1-week return of 90.56% compared to the Sensex's 0.53%. This stark contrast highlights the stock's strong market-beating performance in both the near and long term, as it has outperformed the BSE500 over various periods. However, the limited stake held by domestic mutual funds, at only 0.05%, suggests a lack of confidence in the company's valuation or business prospects, which could temper enthusiasm despite the recent price surge.
