Why is Cochin Malabar falling/rising?

As of 23-Jul, Cochin Malabar Estates & Industries Ltd is experiencing a price increase, currently at Rs 162.00, reflecting a rise of 1.0 (0.62%). Today, the stock opened with a significant gain of 14.84%, reaching an intraday high of Rs 184.9, although it has been highly volatile with an intraday volatility of 7.22%. Despite this positive movement today, the stock has underperformed over the past week and month, with returns of -6.90% and -8.47%, respectively. The company faces challenges, including a negative book value and weak long-term growth, as evidenced by stagnant net sales and a high debt-to-equity ratio. These factors contribute to its classification as a risky investment, despite the recent uptick in price.
In the broader market context, the stock's performance contrasts sharply with the benchmark, the Sensex, which has shown a slight increase of 0.11% over the past week. While Cochin Malabar's recent price movement may suggest a temporary rebound, its long-term performance remains concerning, with a year-to-date decline of -17.66% compared to the Sensex's gain of 5.87%. This underperformance highlights the stock's struggles in the market, despite today's positive price action and increased investor participation, which may not be sufficient to offset its fundamental weaknesses.
