Couch Potato investing is for individuals who want to do their own investing but want to spend very little time on it. This usually means subscribing to a simple (yet effective) approach that only needs attending to a few times a year. Sometimes, just once per year! (depending on how much time you want to spend sitting on that couch).
An example of this is a portfolio of say 5 ETFs. Every 3 months you would add to just these 5 ETFs. In the process you would try to maintain the percentage weightings of each ETF within the portfolio. Simple, eh? The Couch Potato portfolio also goes by other names, such as the 15-minute portfolio, East Chair Portfolio, or even the 1-minute Portfolio.
