Why is Fortis Malar falling/rising?

As of 06-Oct, Fortis Malar Hospitals Ltd is experiencing a significant rise in its stock price, currently at 73.20, reflecting an increase of 8.35 or 12.88%. Today's price summary indicates that the stock opened with a substantial gain of 15.34% and reached an intraday high of Rs 76, marking a 17.19% increase. The stock has outperformed its sector by 9.12%, and it is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Additionally, the stock has shown strong performance over various periods, with a year-to-date return of 20.00% and a one-year return of 25.02%. However, there is a noted decline in investor participation, with delivery volume falling by 3.9% against the 5-day average, which may indicate some caution among investors.
In the broader market context, Fortis Malar's short-term performance significantly outpaces the benchmark Sensex, which has only increased by 1.77% over the past week. The hospital and healthcare services sector has also seen a gain of 3.49%, contributing positively to Fortis Malar's performance. Despite the drop in delivery volume, the overall liquidity remains adequate for trading, suggesting that the stock's upward movement is supported by strong market interest and sector performance.
