Why is PTC India falling/rising?

As of 25-Sep, PTC India Ltd's stock price is currently at 169.50, reflecting a decrease of 2.4, or 1.4%. The stock has been on a downward trend, experiencing consecutive falls for the last four days, resulting in a total decline of 3.03% during this period. Despite this, the stock has outperformed its sector by 0.73% today. Over the past week, PTC India has seen a return of -2.73%, which is worse than the benchmark Sensex's decline of -2.23%. The stock is trading higher than its 200-day moving average but lower than its shorter-term moving averages, indicating mixed momentum. Positive factors include a high dividend yield of 6.81% and strong growth in profit before tax and profit after tax, which suggests attractive valuations compared to peers. However, falling investor participation, as evidenced by a significant drop in delivery volume, may be contributing to the stock's recent decline.
In the broader market context, PTC India's performance over the last month shows a decline of 9.79%, while the Sensex has only fallen by 0.58%, indicating that the stock is underperforming relative to the market. Year-to-date, PTC India has shown a positive return of 16.86%, significantly outperforming the Sensex's 3.87% gain. However, the stock's one-year performance is concerning, with a decline of 19.02% compared to the Sensex's drop of 4.71%. The high institutional holdings at 38.95% may provide some stability, as these investors tend to have a better understanding of the company's fundamentals, but the recent trends in trading volume and price suggest that investor sentiment may be waning.
