Why is Brawn Biotech falling/rising?

As of 23-Jul, Brawn Biotech Ltd's stock price is currently at 17.70, reflecting a decrease of 0.02, or 0.11%. The stock has shown a significant decline over various periods, with a 1-week return of -6.84% and a year-to-date return of -16.94%. Today's trading performance has been described as inline with the sector, but the stock has experienced erratic trading, not trading on one day out of the last 20. Additionally, there has been a notable drop in investor participation, with delivery volume falling by 97.18% against the 5-day average. The company's long-term fundamentals appear weak, with operating losses and a negative EBITDA, which further contributes to the stock's downward movement.
In the broader market context, the Sensex has shown a slight increase of 0.11% over the past week, contrasting with Brawn Biotech's significant decline. The stock has underperformed against the benchmark indices over the last year, with a return of -28.63% compared to the Sensex's gain of 2.86%. This underperformance is compounded by poor financial health indicators, including a weak EBIT to Interest ratio and declining net sales. Overall, the combination of weak fundamentals, declining investor interest, and poor relative performance against the market contributes to the stock's falling price.
