Why is JBM Auto falling/rising?

As of 02-Sep, JBM Auto Ltd is currently priced at 617.95, reflecting an increase of 5.6 (0.91%). The stock has shown a positive performance today, outperforming its sector by 0.65% and has been gaining for the last two days, accumulating a total return of 3.6% during this period. However, despite this recent uptick, the stock has underperformed over the longer term, with a year-to-date decline of 19.44% and a one-year drop of 34.62%. The company has healthy long-term growth indicators, with net sales growing at an annual rate of 29.12% and operating profit at 39.91%. Nevertheless, the high Debt to EBITDA ratio of 3.86 times raises concerns about its ability to service debt, which could negatively impact investor sentiment.
In the broader market context, JBM Auto's short-term return of +0.31% over the past week contrasts with the Sensex's decline of -0.78%, indicating a relative strength in the stock compared to the overall market. However, the stock's performance over the past year has been significantly worse than the market, which saw a decline of only -2.91%. This stark difference suggests that while the stock may be experiencing a short-term rebound, its long-term outlook remains challenged, particularly given its substantial underperformance relative to both the market and its peers. The low participation from domestic mutual funds, holding only 0.24% of the company, further indicates a lack of confidence in the stock's current valuation and business prospects.
