Why is SBC Exports falling/rising?

As of 08-Jul, SBC Exports Ltd's stock price is currently at 15.51, reflecting an increase of 0.2 or 1.31%. The stock has been gaining for the last four days, with a total return of 5.87% during this period. However, it underperformed its sector by 0.52% today, and the delivery volume has decreased by 12.31% compared to the five-day average, indicating a decline in investor participation. Despite a strong ability to service debt and healthy long-term growth in operating profit, the stock has a high valuation with a PEG ratio of 1 and a significant proportion of promoter shares (30.92%) pledged, which can exert downward pressure on the stock price.
In the broader market context, SBC Exports has outperformed the benchmark Sensex in the short term, with a 5.65% return over the past week compared to a mere 0.02% for the index. However, the stock has significantly underperformed over the past year, showing a decline of 15.62% while the market has generated a positive return of 1.98%. This disparity highlights the challenges the company faces in regaining investor confidence, particularly given the increase in pledged shares and the overall negative sentiment surrounding its recent performance.
