Why is Navin Fluo.Intl. falling/rising?

As of 26-Sep, Navin Fluorine International Ltd's stock price is currently at Rs 4,551.00, reflecting a decrease of Rs 206.1 or 4.33%. The stock has underperformed its sector by 2.34% today, touching an intraday low of Rs 4,551. The stock's performance over the past week shows a decline of 5.12%, while it has still managed to achieve a year-to-date increase of 40.17%. Despite strong financial results, including a net profit growth of 128.85% and positive results for the last three consecutive quarters, the stock's valuation appears high with a ROCE of 11.6 and a PEG ratio of 1.2, which may be contributing to its recent price decline.
In the broader market context, the stock's short-term performance has been notably weaker than the benchmark, with the Sensex declining only 2.66% over the same week. While Navin Fluorine has outperformed the market over the past year with a return of 34.82% compared to the Sensex's -6.30%, the recent price drop may reflect concerns over its long-term growth potential, as indicated by an annual operating profit growth rate of only 18.77% over the last five years. The stock's liquidity remains adequate for trading, but the combination of high valuation metrics and recent underperformance against the sector may be influencing investor sentiment negatively.
