However, the stock's longer-term performance over the past year shows a decline of 18.25%, while the Sensex has remained relatively flat with a decrease of only 0.35%. This mixed performance indicates that while Positron Energy has had strong short-term gains, it faces challenges in sustaining its momentum in the longer term.
