Why is Karnataka Bank falling/rising?

As of 20-Aug, Karnataka Bank Ltd's stock price is currently at 171.95, reflecting a decrease of 0.85, or 0.49%. The stock has shown a trend reversal, falling after two consecutive days of gains. It is performing inline with its sector today, but the delivery volume has decreased by 22.66% compared to the 5-day average, indicating falling investor participation. Over the past week, the stock has gained 0.88%, but it has significantly underperformed over the last month and year, with returns of -10.30% and -21.27%, respectively. Despite strong long-term fundamentals, including a low Gross NPA ratio and a healthy CAGR growth in net profits, the stock has faced negative pressure due to three consecutive quarters of disappointing results, including a significant drop in profit before tax.
In the broader market context, while the Sensex has increased by 1.64% over the past week, Karnataka Bank's performance has lagged behind, highlighting its struggles relative to the benchmark. The stock's year-to-date return of -19.76% starkly contrasts with the Sensex's positive return of 4.76%, indicating a significant underperformance in the market. The high institutional holdings at 32.66% suggest that informed investors are still backing the stock, but the recent negative results and declining investor participation may be causing concern among retail investors, contributing to the stock's current downward movement.
