Share Market (White Giant)

I'd like to hear from experienced players about how they play their investment fund share market, if at all. I know that it affects the overall wealth of the country, but I find it such a time intensive task to manage it when the automatic system is there. What kinds of profit levels do you all get?

i've been trying to figure that out for months. i don't think it affects anything. i actively manage it since it gives me something else to do.
