Why is Picturehouse falling/rising?

As of 11-Sep, Picturehouse Media Ltd's stock price is currently at 8.60, reflecting an increase of 0.25, or 2.99%. The stock has been gaining momentum over the last two days, with a total return of 13.16% during this period. It is also outperforming its sector by 4.21%. However, despite these short-term gains, the company has a negative book value and weak long-term fundamental strength, indicated by a significant decline in net sales and operating profit over the past five years. The stock's high debt levels and negative EBITDA further contribute to its risky profile, which may temper investor enthusiasm despite recent price increases.
In the broader market context, Picturehouse's short-term performance shows a 2.63% increase over the past month, while the benchmark Sensex has risen by 1.17% during the same period. However, the stock's year-to-date performance remains concerning, with a decline of 11.79% compared to the Sensex's gain of 4.36%. This disparity highlights the stock's volatility and the challenges it faces in maintaining investor confidence, especially given its poor long-term growth prospects and recent flat financial results.
