Why is Austin Engg Co falling/rising?

As of 15-Sep, Austin Engineering Company Ltd's stock price is currently at 160.70, reflecting a decline of 4.3 points or 2.61%. The stock has been underperforming, having lost 9.21% over the last three days and opened today with a loss of 3.03%. It reached an intraday low of Rs 156, which is a decrease of 5.45%. Despite trading volumes showing a significant increase, with a 350.03% rise in delivery volume on September 12 compared to the five-day average, the stock's performance remains weak. Over the past week, the stock has declined by 12.99%, and year-to-date, it has fallen 15.40%. Unfortunately, there is no information available regarding positive or negative factors that could further explain the stock's recent movement.
In the broader market context, the stock's short-term performance has been notably poor compared to the benchmark, with the Sensex gaining 1.24% over the past week while Austin Engineering has dropped significantly. This stark contrast highlights the stock's struggles relative to the overall market, which has seen a modest increase. Additionally, while the stock has shown strong returns over longer periods, such as a 42.28% increase over three years and a remarkable 363.78% over five years, the recent downturn suggests a troubling trend that diverges from the broader market's performance.
