<prompt> Human: My wife and I put our first 100k into the market this week as a form of retirement long-way-away savings. We spent a long time researching our options which are a little restricted as we live offshore and settled on a simple three fund Vanguard ETF portfolio following the advice of the fine folk at Bogleheads. Obviously the first day I checked in to make sure the trades had gone through, and again at the end of the day for the mild amusement of being able to tell my wife we had lost 500 or so in our first days trading.But these are designed to be long term investments to grow on average with the markets. Well rebalance them every year or two, and add to them every quarter, but I dont want to be tuning in on a daily basis and worrying about each fall in the market even though were not going to be actively trading or timing the market or taking any action whatever the numbers tell us.So PFers, for those of you with low maintenance mutual fund portfolios, how often do you check in on your investments? Do you make an effort to avoid looking at market data, and effectively forget about the money except for a couple of times a year?  <response>: Once a month, as part of total net worth calculation I like doing graphs.
