Why is Navin Fluo.Intl. falling/rising?

As of 15-Jul, Navin Fluorine International Ltd is experiencing a price increase, currently at Rs 5,075.35, reflecting a rise of Rs 106.35 or 2.14%. The stock is close to its 52-week high, just 1.17% away from Rs 5,134.65, and has outperformed its sector by 1.05% today. Over the past week, the stock has gained 0.59%, and it has shown impressive returns of 12.14% over the last month and 56.32% year-to-date. The company's strong performance is supported by high management efficiency, evidenced by a return on capital employed (ROCE) of 16.05%, and a low debt to EBITDA ratio of 1.08 times, indicating a solid ability to service debt. However, there are concerns regarding long-term growth, as operating profit has only grown at an annual rate of 12.84% over the last five years.
In the broader market context, while Navin Fluorine has outperformed the Sensex, which has declined by 1.36% over the past week, the stock's strong performance over the last year, generating a return of 38.70% compared to the market's 2.36%, highlights its resilience. Despite a decrease in investor participation, with delivery volume falling by 28.16% against the five-day average, high institutional holdings at 50.2% suggest confidence among more sophisticated investors. The stock's valuation appears expensive with a PEG ratio of 3.3, but its recent operational results, including record net sales and operating profit margins, contribute positively to its current upward price movement.
