<prompt> Human: The company I work for currently matches up to 6 through Merrill Lynch. I am contributing the 6.Currently 30 years old looking to get the best out of my 401k but have no idea what to diversify into. I know they say to be more aggressive when youre younger.Any advice?  <response>: At your level of understanding, a lifecycle fund or target-date fund is probably your best bet for now. As you get more knowledgeable, you can move into individual fund investing with more diversification and fewer overall fees.A target-date 2055 fund is going to be roughly 9010 stocks and bonds, which is plenty aggressive.
