Yes Bank stock, which was once trading around ₹400, experienced a significant decline to around ₹20 due to problems in its loan book and corporate governance issues, illustrating the impact of negative company-specific events on stock price and the potential for large losses if losses are not booked.
"Let's say we are taking the example of Yes Bank. The stock was trading at almost ₹400 at one point and time. ... Because eventually a lot of problems started to crop up in that company. People started to talk about the problems in the loan book. There were a lot of issues around corporate governance, and then the stocks slid down from 400 to 300 to 200 and even below 100 levels. ... because today the same stock trades at around ₹20."
