Why Bajaj Finance share is down 90% today?

So, in reality, Bajaj Finance share was not down 90% today. The share had an X-Bonus and X-Split rate. That means, in the result of quarter 4, Bajaj Finance announced a stock split of 1:2 and a bonus of 4:1. That means, before today, the person who had 1 Bajaj Finance share now has 10 shares. In other words, 9 shares have been given additionally. But, there’s no such thing as “free” in the stock market. If extra shares are given, the price gets adjusted accordingly. The price of Bajaj Finance, which was around ₹9300 earlier, has now come down to around ₹930. The remaining shares (bonus and split adjusted) will be credited to your demat account by 27th June. Earlier, the last time Bajaj Finance announced a stock split and bonus together was in 2016. Now, after 9 years, they have again declared both together. So no, Bajaj Finance share is not down 90% today. This movement is simply due to its X-Bonus and X-Stock Split date.
