Why is Fortis Malar falling/rising?

The stock has been gaining for the last two days, with a total return of 2.78% during this period. It outperformed its sector by 2.33% today and reached an intraday high of Rs 72, which is a 4.77% increase. However, the stock's delivery volume has decreased by 24.04% compared to the five-day average, indicating a decline in investor participation.

In the broader market context, Fortis Malar's recent performance contrasts with the Sensex, which has declined by 1.06% over the past week. While the stock has shown resilience with a positive return in the short term, its one-month performance is down by 3.42%, slightly better than the Sensex's decline of 3.70%. The stock's longer-term performance over three years shows a gain of 23.79%, but it lags behind the Sensex's 38.69% increase. This suggests that while Fortis Malar is experiencing short-term gains, it faces challenges in maintaining momentum compared to the broader market trends.
