Why is Austin Engg Co falling/rising?

As of 19-Sep, Austin Engineering Company Ltd's stock price is currently at 170.50, reflecting an increase of 5.35 or 3.24%. The stock has shown strong performance today, outperforming its sector by 3.05% and reaching an intraday high of Rs 173.95. Over the past week, the stock has risen by 3.33%, and in the last month, it has increased by 7.27%. Despite a year-to-date decline of 10.24% and a significant drop of 24.39% over the past year, the stock's recent movement is supported by rising investor participation, as evidenced by a 73.11% increase in delivery volume compared to the 5-day average. The stock's valuation appears attractive with a Price to Book Value of 0.9, and while its profits have only risen by 1% over the past year, it is trading at fair value relative to its peers.
In the broader market context, the stock's short-term return of 3.33% over the past week significantly outperforms the Sensex, which has only increased by 0.88% in the same period. This positive momentum contrasts with the stock's long-term performance, where it has underperformed the market over the past year. The company's weak long-term fundamental strength, indicated by an average Return on Equity (ROE) of 4.53% and flat results in June, raises concerns about its growth potential. Despite these challenges, the stock's recent upward movement can be attributed to favorable trading conditions and investor interest, suggesting a potential shift in market sentiment.
