JQuery Pulse

$.fn.animateHighlight = function(highlightColor, duration) {
    var highlightBg = highlightColor || "#FFFF9C";
    var animateMs = duration || 1500;
    var originalBg = this.css("backgroundColor");
    this.stop().css("background-color", highlightBg).animate({backgroundColor: originalBg}, animateMs);
};

Used like this: 

$("#PortfolioBeta").text(result.PortfolioBeta).animateHighlight("#FFBD1A", 1000);

Simplest pulse ever.
