Why is SpiceJet falling/rising?

As of 10-Sep, SpiceJet Ltd's stock price is currently at 33.06, reflecting a decline of 0.21, or 0.63%. The stock has been underperforming significantly, having lost 7.99% over the last six days and is trading below all key moving averages. In the past year, SpiceJet has generated a return of -49.58%, and its recent quarterly performance shows a substantial drop in net sales and profit after tax, indicating weak financial health. The company also has a negative book value and a high debt-to-equity ratio, which contributes to its classification as a strong sell. Additionally, 43.99% of promoter shares are pledged, which can exert further downward pressure on the stock price in a declining market.
In the broader market context, SpiceJet's performance contrasts sharply with the benchmark Sensex, which has gained 1.06% over the past week and 4.21% year-to-date. While the Sensex has shown positive returns, SpiceJet's stock has declined by 7.65% over the past week and 40.32% year-to-date, highlighting its significant underperformance relative to the market. This disparity underscores the challenges facing SpiceJet, including poor long-term growth prospects and negative earnings before interest, taxes, depreciation, and amortization (EBITDA), which further diminishes investor confidence.
