<prompt> Human: Hello rpersonalfinance,Novice question, but there seems to be a lot of intelligent people in here who are more informed than I am and could possibly provide some help.I currently have a 401k through my employer no match and Ive saved up a decent amount of money in there over the past 2-3 years.I was chatting with some coworkers yesterday and one mentioned pulling the funds out of his 401k because of the situations in China and Greece.Now, he is a smart dude, but I dont know how much he understands finance, so I was hoping someone in here might have a better grasp.How, in any way, would a standard 401k would be affected by Greece and Chinas financial situations?Any info would be helpful. Thanks in advance.EDIT: I am invested in the Northern Trust and TRPFrontier, if that helps.  <response>: It will affect your 401k in that the daily balance may jump up and down a lot. You should not look at the daily balance of your 401k - think of it as something that youre playing a very long game on. Youre interested in yearly performance and five year performance, not day to day, month to month.In the long run the market will almost certainly be OK and trying to time the market with 401ks with relatively small amounts of change like this is a fools game.
