And what's the problem looping it? You are doing something opposite to the idea of programming. Never repeat anything. Don't repeat $('div'), calculate it once and same in the variable. And so on...

Try this:

XML

<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
$(document).ready(function()
{
  var $selector = $('div');
  var displacement = 0;

  for (i=0;i<4;i++){
     displacement += 50;
     $selector.animate({left: displacement});
     $selector.animate({left: 0});
     $selector.animate({top: displacement});
     $selector.animate({top: 0});
  }
});
</script>
</head>
<body>
<div style="position:relative;background:#ff0000;height:100px;width:100px;">
