Why is the dominant investing advice for individuals to use mutual funds, exchanged traded funds (ETFs), etc
Why is that? With all the successful investors (including myself on a not-infrequent basis) going for individual companies directly, wouldn't it make more sense to suggest that new investors learn how to analyse companies and then make their best guess after taking into account those factors? I have a different perspective here than the other answers.  I recently started investing in a Roth IRA for retirement. I do not have interest in micromanaging individual company research (I don't find this enjoyable at all) but I know I want to save for retirement. Could I learn all the details? Probably, as an engineer/software person I suspect I could. But I really don't want to. But here's the thing: For anyone else in a similar situation to me, the net return on investing into a mutual fund type arrangement (even if it returns only 4%) is still likely considerably higher than the return on trying to invest in stocks (which likely results in $0 invested, and a return of 0%). I suspect the overwhelming majority of people in the world are more similar to me than you - in that they have minimal interest in spending hours managing their money. For us, mutual funds or ETFs are perfect for this.
