Once the label is created, Win32::GUI doesn't expose a method to let you change the color. You might be able to use a custom Hook method to override painting the label.

An alternative would be to create two labels, one red and one green. Make them identical in size and location in the window. Update the green one when the stock goes up, update the red one if the stock goes down.
