Why is MRF falling/rising?

As of 20-Oct, MRF Ltd. is experiencing a price increase, with its current price at Rs. 161,000.00, reflecting a rise of Rs. 5,144.3 or 3.3%. The stock has recently hit a new 52-week and all-time high of Rs. 163,400, indicating strong upward momentum. Over the past week, MRF has gained 2.64%, and in the last month, it has risen by 7.38%. Despite underperforming its sector by 0.57% today, the stock has shown consistent gains over the last three days, accumulating a total return of 3.7%. MRF's strong performance is supported by a low debt-to-equity ratio, healthy long-term growth in net sales and operating profit, and high institutional holdings, which suggest confidence in the company's fundamentals.
In the broader market context, MRF's recent performance has outpaced the Sensex, which has increased by 2.47% over the same week. The stock's year-to-date return of 23.62% significantly exceeds the Sensex's 7.97%, highlighting its strong market position. Furthermore, MRF has demonstrated superior returns compared to the BSE500 over various time frames, reinforcing its status as a market leader in the tyre sector. However, a notable risk is the decline in investor participation, with delivery volume dropping by 43.27% against the five-day average, which could signal potential volatility ahead.
