Why is ABS Marine falling/rising?

As of 05-Aug, ABS Marine Services Ltd is experiencing a decline in its stock price, currently at Rs 201.00, which reflects a decrease of Rs 10.0 or 4.74%. The stock has underperformed its sector by 4.7% today, and it reached an intraday low of Rs 200.55, indicating significant selling pressure. Over the past week, the stock has seen a return of -8.93%, and it has also underperformed over the past month with a return of -1.88%. Despite some positive signs, such as a 30.05% increase in delivery volume on 04 Aug compared to the 5-day average, the overall trend remains negative, with a one-year return of -32.40% compared to a positive 2.47% for the Sensex.
In the broader market context, the stock's recent performance contrasts sharply with the benchmark, as it has significantly underperformed the Sensex, which has shown a modest decline of only 0.69% over the past week. While ABS Marine's liquidity appears sufficient for trading, the erratic trading pattern, with the stock not trading on one day out of the last 20, may contribute to investor uncertainty. The stock's moving averages indicate that it is currently lower than the shorter-term 5-day and 20-day averages, which could further signal bearish sentiment among investors.
