Why is Aether Industri. falling/rising?

As of 23-Sep, Aether Industries Ltd is experiencing a decline in its stock price, currently at Rs 741.00, which reflects a decrease of Rs 12.05 or 1.6%. The stock has underperformed its sector by 1.04% today and has fallen after three consecutive days of gains. It is also close to its 52-week low, being just 2.21% away from Rs 724.6. Over the past week, the stock has shown a slight increase of 0.59%, but it has significantly underperformed over the longer term, with a year-to-date decline of 16.21% and a one-year drop of 23.96%. Despite positive financial results in the last three quarters, including a substantial growth in profit after tax, the stock's performance has been hampered by poor long-term growth prospects and a high price-to-book value ratio, indicating an expensive valuation relative to its peers.
In the broader market context, the stock's recent performance contrasts with the Sensex, which has shown a slight decline of 0.34% over the past week and a positive return of 5.07% year-to-date. This consistent underperformance against the benchmark, coupled with a reduction in promoter confidence—evidenced by a 6.77% decrease in their stake—suggests a lack of investor confidence in the company's future. Additionally, the stock's liquidity remains adequate for trading, but the overall sentiment appears to be negative due to the company's long-term growth challenges and its significant underperformance relative to the broader market over the past three years.
