Why is Grindwell Norton falling/rising?

As of 15-Jul, Grindwell Norton Ltd. is experiencing a price increase, currently at 1,741.25, with a change of 9.25, representing a rise of 0.53%. The stock has shown a positive performance today, outperforming its sector by 0.47%, and has gained consecutively over the last two days, yielding a total return of 1.29% during this period. Despite this short-term gain, the stock has underperformed in the longer term, with a year-to-date decline of 9.47% and a significant drop of 34.66% over the past year. The company benefits from high management efficiency, indicated by a return on equity (ROE) of 18.29%, and a low debt-to-equity ratio, which are positive factors. However, the stock faces challenges due to poor long-term growth, with net sales and operating profit growth rates of only 12.22% and 15.26%, respectively, over the last five years, and a flat performance in recent results.
In the broader market context, the stock's recent performance contrasts with the benchmark, as it has outperformed the Sensex by 0.41% in the short term, given that the Sensex has declined by 1.36% over the past week. However, the stock's long-term performance remains concerning, as it has significantly lagged behind the benchmark indices over various periods, including a 34.66% decline in the past year compared to the Sensex's 2.36% increase. The high institutional holdings at 25.02% suggest that knowledgeable investors are backing the stock, yet the overall flat results and expensive valuation metrics indicate that there are substantial risks that could impact future performance.
