Why is HBL Engineering falling/rising?

As of 19-Nov, HBL Engineering Ltd's stock price is currently at 935.55, reflecting a decline of 93.45 points or 9.08%. The stock has been underperforming, having fallen for three consecutive days with a total drop of 10.2% during this period. Today's trading opened with a loss of 2.92%, and the stock reached an intraday low of Rs 930.15. Despite a strong performance over the longer term, with a year-to-date increase of 50.17% and a remarkable 773.94% rise over the past three years, the recent downturn is notable. The company has shown healthy growth metrics, including a significant increase in net sales and operating profit, but the current decline may be influenced by a drop in investor participation, as evidenced by a 71.89% decrease in delivery volume compared to the five-day average.
In the broader market context, HBL Engineering's recent performance contrasts sharply with the Sensex, which has gained 0.85% over the past week. The stock's short-term return of -4.13% over the last week indicates a significant underperformance relative to the benchmark. Additionally, the overall sector, particularly the Batteries sector, has also seen a decline of 3.07%. While institutional investors have increased their stake in HBL Engineering, suggesting confidence in its long-term prospects, the stock's current valuation appears expensive, which may be contributing to the recent price drop.
