Why is JBM Auto falling/rising?

As of 18-Aug, JBM Auto Ltd's stock price is currently at Rs 624.50, reflecting an increase of Rs 16.1 or 2.65%. The stock has shown a positive trend recently, gaining 5.22% over the last five days, although it underperformed its sector by 0.65% today. Despite this recent uptick, the stock has a mixed performance history, with a year-to-date decline of 18.58% and a one-year drop of 34.74%. The company has demonstrated healthy long-term growth with net sales increasing at an annual rate of 29.12% and operating profit at 39.91%. However, it faces challenges, including a high Debt to EBITDA ratio of 3.86 times, which indicates a low ability to service debt, and disappointing quarterly results showing a 27.1% decline in PAT.
In the broader market context, JBM Auto's recent performance contrasts with the benchmark, as the Sensex has gained 0.83% over the past week while JBM Auto has risen by 5.06%. Despite the stock's recent gains, it has significantly underperformed the market over the past year, with a return of -34.74% compared to the BSE500's -1.14%. This underperformance may be reflected in the low participation from domestic mutual funds, which hold only 0.24% of the company, suggesting a lack of confidence in its current valuation or business outlook. Overall, while the stock has seen short-term gains, its long-term challenges and underperformance relative to the market raise concerns about its sustainability.
