I HATE POSTERS LIKE YOU. I posted to make you nervous and to be dumb. This is the stock market. No one is giving away free money or handing you all the answers. No news means just that, NO NEWS! Nothing happened. It has low liquidity and someone wanted to sell more shares than the market could absorb. Hard price drop. Just buy more during this or don't watch. You can't explain every tiny movement nor is every tiny movement a prediction for Armageddon or a strong price appreciation. You own a great bank, now don't watch the stock price for atleast a year and you will be much better off.
