Why is Kaiser Corporat. falling/rising?

As of 08-Sep, Kaiser Corporation Ltd's stock price is currently at 5.41, reflecting an increase of 0.06 or 1.12%. The stock has been gaining for the last three days, with a total return of 3.64% during this period. However, it has underperformed its sector by 0.72%. Despite this recent uptick, the stock has shown significant long-term weaknesses, including a high Debt to EBITDA ratio of 4.92 times and negative operating results, with net sales and profit after tax both declining by 31.06%. Additionally, the promoters have reduced their stake by 4.4%, indicating a lack of confidence in the company's future prospects, which may contribute to the stock's overall negative sentiment.
In the broader market context, Kaiser Corporation's short-term return of 3.05% over the past week significantly outpaces the Sensex's return of 0.53%. However, the stock has consistently underperformed against the benchmark over the last three years, with a staggering decline of 93.09% compared to the Sensex's 35.35% gain. This persistent underperformance, coupled with the company's weak fundamentals and declining investor participation, suggests that while there may be short-term gains, the long-term outlook remains precarious.
