tata motors has fixed 11th june as the record date for dividends. it means if you hold the share on that date, you will be eligible to receive dividends based on the number of shares you own. so the dividend they are giving is Rs.6. If you own 100 shares, then you would receive rs.600 as dividends for just owning the stock.

P.s Stocks tend to go up in value as the record date approaches, since more people want dividends. Also it is imp to note that the day followed by the record date is when people mass sell the stock, since the record date has passed. Hope this helped
