Why is SAL Automotive falling/rising?

As of 22-Sep, SAL Automotive Ltd's stock price is currently at 255.65, reflecting an increase of 2.75 or 1.09%. Today, the stock opened with a significant gain of 7.91%, reaching an intraday high of Rs 272.9. However, despite this positive movement, the stock has underperformed in the longer term, with a year-to-date decline of 6.01% and a staggering 31.74% drop over the past year. The company has shown healthy long-term growth with net sales increasing at an annual rate of 39.82%, but it has also faced challenges, including a flat EPS of Rs 1.79 in the last quarter and a significant decline in investor participation, as evidenced by a 50.52% drop in delivery volume compared to the five-day average.
Broader market context indicates that while SAL Automotive's stock has outperformed its sector by 1.2% today, it has lagged behind the benchmark Sensex in the past year, which only fell by 2.82%. The stock's performance over the last week and month has also been negative at -0.91% and positive at +0.71%, respectively, indicating volatility. The company's attractive valuation, with a return on capital employed (ROCE) of 13.2 and a PEG ratio of 22, suggests potential for recovery, but the significant underperformance relative to the broader market raises concerns about its future trajectory.
