Why is Shanthi Gears falling/rising?

As of 30-Sep, Shanthi Gears Ltd. is experiencing a decline in its stock price, currently at 515.80, reflecting a decrease of 8.15 points or 1.56%. The stock has been underperforming, having fallen consecutively for the last five days, resulting in a total return of -7.19% over the past week. Additionally, the stock's performance today underperformed its sector by 0.94%. Despite having a low Debt to Equity ratio and healthy long-term growth in operating profit, the company has reported flat results in June, with a significant drop in net sales and the lowest debtors turnover ratio. The stock's valuation appears expensive relative to its peers, and domestic mutual funds hold a minimal stake, indicating a lack of confidence at current price levels.
In the broader market context, the stock's short-term performance contrasts sharply with the benchmark, as the Sensex has only declined by 2.23% over the same week. Over the past year, while the broader market (BSE500) has seen a negative return of -6.58%, Shanthi Gears has significantly underperformed with a return of -18.27%. This disparity highlights the stock's struggles relative to the market, contributing to investor concerns and the recent downward trend in its price.
