Why is AastamangalamFin falling/rising?

As of 04-Aug, Aastamangalam Finance Ltd's stock price is currently at Rs 38.05, reflecting a decline of 2.0 (-4.99%). The stock has been underperforming significantly, having lost 23.13% over the last seven days and underperformed its sector by 6.61% today. Despite showing positive results over the last six quarters, including a 91.28% growth in net sales and a 92.8% increase in profits over the past year, the stock's recent performance has been overshadowed by its consecutive price falls. Although it has a fair valuation compared to peers and a relatively attractive PEG ratio of 0.4, the weak long-term fundamental strength indicated by an average Return on Equity (ROE) of 6.65% may be contributing to investor concerns.
In the broader market context, Aastamangalam Finance Ltd's short-term performance has been notably poor, with a 1-week return of -18.26%, contrasting sharply with the Sensex, which has gained 0.16% during the same period. This stark difference highlights the stock's struggles relative to the market. While the company has demonstrated strong growth metrics and has outperformed the BSE500 over the longer term, the recent price declines suggest that investor sentiment is currently negative, likely influenced by the stock's ongoing losses and the broader market's stability.
