The Annual Dividend function does not return any value

I am developing a spreadsheet in Numbers and I have used the "annual dividend" function on it, however I am not getting any value for stocks I know pay a dividend. My function is:

=STOCK("AAPL";"annual dividend")

All I get is an error sign saying "data for the annual dividend attribute isn't available for the selected symbol". Do I need to enter symbols in a different way? Why all other attributes work but not the dividend-related ones?

Thank you.
