Why is Le Travenues falling/rising?

As of 19-Sep, Le Travenues Technology Ltd's stock price is currently at Rs 285.25, reflecting an increase of Rs 12.35 or 4.53%. The stock has shown a positive performance today, outperforming its sector by 3% and achieving a consecutive gain over the last two days with a total return of 5.32%. Despite a recent decline of 7.79% over the past week, the stock has performed well on a longer-term basis, with a year-to-date increase of 70.04% and a remarkable 92.74% rise over the past year. The company has demonstrated strong financial health, with a low debt-to-equity ratio and impressive growth in net sales and operating profit, which has likely contributed to the stock's upward movement.
Broader market context indicates that while the stock has outperformed the broader market, as represented by the Sensex, which has only increased by 0.88% over the past week, the stock's recent performance is noteworthy given the overall negative return of -1.96% in the BSE500 index over the last year. The high institutional ownership at 70.84% suggests confidence from knowledgeable investors, which may bolster the stock's stability and attractiveness. However, the stock's high valuation, indicated by a Price to Book Value of 17.6 and a return on equity of 8.9, raises concerns about its sustainability in the long term, especially as profits have only risen by 19% despite significant stock price appreciation.
