Why is Tanla Platforms falling/rising?

As of 15-Sep, Tanla Platforms Ltd is currently priced at 688.65, reflecting a decrease of 7.1 points or 1.02%. The stock has been underperforming recently, having lost 2.15% over the last two days and is currently trading lower than its sector by 0.55%. Despite this short-term decline, the stock has shown positive performance over the past week and month, with returns of 4.18% and 13.00%, respectively. However, the stock has experienced a significant drop of 27.05% over the past year, indicating a longer-term struggle despite healthy operating profit growth and a low debt-to-equity ratio. The recent increase in promoter stake by 1.39% signals confidence in the company's future, which may provide some support against the recent price decline.
In the broader market context, Tanla Platforms has outperformed the Sensex in the short term, with a 1-week return of 4.18% compared to the benchmark's 1.24%. However, the stock's year-to-date performance of 2.48% lags behind the Sensex's 4.67%, suggesting that while there are positive indicators, the overall market sentiment may not be favorable for Tanla Platforms at this time. The falling investor participation, as evidenced by a significant drop in delivery volume, could also be contributing to the stock's recent price movement, indicating a lack of confidence among traders despite some positive fundamentals.
