Why is Brawn Biotech falling/rising?

As of 30-Sep, Brawn Biotech Ltd's stock price is currently at Rs 21.06, reflecting an increase of 1.0 or 4.99%. The stock has been gaining for the last two days, with a total return of 10.2% during this period. It opened with a gain of 4.99% today and reached an intraday high of Rs 21.06. Despite this positive movement, the stock has experienced a decline of 10.00% over the past month and a slight decrease of 1.17% year-to-date. Additionally, the stock's delivery volume has fallen by 1.44% against the five-day average, indicating a decrease in investor participation, which could be a concern for sustained upward momentum.
In the broader market context, Brawn Biotech's recent performance contrasts with the Sensex, which has declined by 2.23% over the past week. While the stock has outperformed its sector by 5.58% today, its longer-term performance shows a mixed picture, with a 1Y return of 9.40% compared to the Sensex's decline of 4.78%. The stock's performance over three years is notably lower than the benchmark, with a return of 14.77% against the Sensex's 39.77%. This suggests that while the stock is currently experiencing a rise, its overall performance relative to the market has been inconsistent, highlighting potential volatility and investor caution.
