Need content to show after "the_post"

I am working on a plugin that will need to have some “stuff” show up on a page. I am using the “the_post” hook and my “stuff” is showing up before the page’s title. Here is my code:

function stuff_to_show_after_post($post)
{
//stuff here
}
add_action(‘the_post’, “stuff_to_show_after_post”);

How can I have my stuff show up after “the_post”?

I’m sorry if this is a simple question, I just can’t find the hook to use.

thanks in advance for any direction you can give me.
