Why is N K Industries falling/rising?

As of 29-Sep, N K Industries Ltd's stock price is currently at Rs 71.50, reflecting an increase of Rs 6.5 or 10.0%. Today, the stock opened with a significant gain of 9.85% and reached an intraday high of Rs 71.5. Despite this positive movement, the stock has shown erratic trading patterns, not trading on one day out of the last 20. Over the past year, N K Industries has generated a return of 36.74%, outperforming the BSE500 index, but it faces challenges such as a negative book value and high debt levels, which contribute to its weak long-term fundamental strength.
In the broader market context, the stock's recent performance has been relatively strong, with a 3.62% increase over the past month, contrasting with the Sensex's modest gain of 0.70%. However, the stock's performance over the last week has been negative at -1.05%, while the Sensex fell by 2.18%. Despite the current rise, the stock's liquidity is concerning, with a significant drop in delivery volume, indicating falling investor participation. Overall, while N K Industries has shown impressive long-term returns, its recent volatility and fundamental weaknesses suggest a complex outlook for investors.
