of course don't just throw 50% of your portfolio into small caps but maybe 1-2% of your portfolio per small cap and you pick maybe 5 small caps that's a total of 5-10% of your portfolio and maybe throw 5% into IWM for good measure then you're good to ride this wave up and yes you need to monitor them because these small caps they rise fast but they also fall faster than mega caps so you have to be careful and watch them daily and set reasonable price targets don't get greedy but don't be too fearful as well
