Why is MRF falling/rising?

As of 18-Jul, MRF Ltd. is experiencing a decline in its stock price, currently at Rs 147,617.05, which reflects a decrease of Rs 2,933.15 or 1.95%. The stock has underperformed its sector by 1.02% today and has seen a consecutive fall over the last two days, resulting in a total drop of 3.1%. Despite this recent downturn, MRF has shown strong performance over the longer term, with a 1-month return of 7.13% and a year-to-date increase of 13.34%. The company maintains a low debt-to-equity ratio and has demonstrated healthy long-term growth with net sales increasing at an annual rate of 11.63%. Additionally, high institutional holdings at 29.76% suggest that informed investors continue to support the stock, although falling investor participation, as indicated by a 20.95% drop in delivery volume, may be contributing to the current price decline.
In the broader market context, MRF's short-term performance has been relatively better than the benchmark, with a 1-week return of -0.64% compared to the Sensex's -0.90%. However, the stock's recent underperformance and consecutive losses could be impacting investor sentiment. While MRF's long-term performance has outpaced the BSE500 over various periods, the current liquidity and trading activity suggest some caution among investors. The stock remains liquid enough for trading, but the recent drop in delivery volume indicates a potential decrease in demand, which may be influencing the stock's price movement negatively at this time.
