Why is SAB Events falling/rising?

As of 21-Jul, SAB Events & Governance Now Media Ltd's stock price is currently at 7.69, reflecting an increase of 0.36 or 4.91%. The stock has been on an upward trend, gaining 15.47% over the last three days and outperforming its sector by 5.88% today. Despite this short-term positive movement, the company has a negative book value and weak long-term fundamental strength, as evidenced by a decline in net sales over the past five years and a high debt-to-EBITDA ratio. Additionally, 73.69% of promoter shares are pledged, which could exert downward pressure on the stock in a falling market. The stock has underperformed over the last year, generating a return of -26.13%, while the broader market has seen modest gains.
In the broader market context, SAB Events has significantly outperformed the benchmark in the short term, with a 1-week return of +17.40% compared to a negligible -0.06% for the Sensex. However, the stock's year-to-date performance remains concerning, with a decline of -56.72%, contrasting sharply with the Sensex's increase of +5.20%. This disparity highlights the stock's volatility and the challenges it faces despite recent gains. The falling investor participation, indicated by a drastic drop in delivery volume, suggests caution among investors, which may impact future price movements.
