Why is Websol Energy falling/rising?

As of 19-Sep, Websol Energy System Ltd is experiencing a slight decline in its stock price, currently at 1,291.75, reflecting a change of -0.25 (-0.02%). The stock has underperformed its sector today by 1.94% and has fallen after two consecutive days of gains. In terms of returns, the stock has seen a decrease of 0.38% over the past week and 1.57% over the past month, while it has generated a notable return of 33.16% over the last year. Despite the healthy long-term growth indicated by a 33.03% annual increase in net sales and a 39.18% growth in net profit, the stock's valuation appears expensive with a high ROCE of 61.5 and a PEG ratio of 0. Additionally, 88.12% of promoter shares are pledged, which can exert downward pressure on the stock price in a falling market.
In the broader market context, the Sensex has increased by 0.88% over the past week and 1.20% over the past month, contrasting with Websol Energy's negative short-term performance. While the stock has outperformed the BSE500 over the last three years, the recent decline in investor participation, as evidenced by a 12.16% drop in delivery volume, suggests a lack of confidence among investors. The stock's current liquidity is adequate for trading, but the combination of high promoter pledging and an expensive valuation may contribute to its recent price decline, despite the company's strong operational results.
