Why is Picturehouse falling/rising?

As of 02-Sep, Picturehouse Media Ltd is experiencing a price increase, currently at 8.90, reflecting a rise of 0.62 or 7.49%. The stock has shown strong performance recently, outperforming its sector by 6.77% today and achieving consecutive gains over the last three days, resulting in a total return of 16.04% during this period. Despite this positive short-term movement, the company faces significant challenges, including a negative book value and a weak long-term fundamental strength, with net sales declining at an annual rate of -68.30% over the past five years. Additionally, the company has a high debt-to-equity ratio and has reported flat results in its latest quarterly earnings, indicating ongoing financial struggles.
In the broader market context, Picturehouse's short-term return of +13.81% over the past week contrasts sharply with the Sensex, which has declined by -0.78% during the same period. This indicates that Picturehouse is not only gaining in value but is also benefiting from a favorable comparison against the broader market. However, the stock's year-to-date performance remains negative at -8.72%, while the Sensex has gained 2.58%, highlighting the volatility and risks associated with Picturehouse despite its recent gains.
