Why is Navin Fluo.Intl. falling/rising?

As of 23-Jul, Navin Fluorine International Ltd is experiencing a price increase, currently at 5,050.00, reflecting a rise of 61.0 points or 1.22%. The stock has shown strong performance recently, gaining 3.67% over the last three days and outperforming its sector by 1.53%. It is also trading close to its 52-week high, just 1.68% away from Rs 5,134.65. The stock has generated impressive returns, with a 1-week increase of 1.81%, a 1-month increase of 9.01%, and a year-to-date increase of 55.54%. Positive factors contributing to this upward movement include high management efficiency indicated by a return on capital employed (ROCE) of 16.05%, strong debt servicing ability with a low Debt to EBITDA ratio of 1.08 times, and significant institutional holdings which have increased by 3.19% over the previous quarter. 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, and the stock is considered expensive with a PEG ratio of 4.
In the broader market context, Navin Fluorine's recent performance has significantly outpaced the benchmark, with a 1-year return of 42.37% compared to the BSE500's 1.79%. This strong performance relative to the market may be attracting more investors, despite a noted decline in delivery volume, which fell by 34.63% against the 5-day average. The stock's liquidity remains adequate for trading, which could further support its price stability. Overall, while the stock is rising due to strong recent performance and positive financial indicators, the concerns regarding its long-term growth and valuation may temper some investor enthusiasm.
