Beyond that, I do agree that whole life insurance can be useful in certain situations when structured properly. But those situations are few and far between and they require the help of someone who both knows the ins and outs of these policies AND is willing to put the client’s interests over their own financial interests (i.e. minimizing commissions and other costs on the policy). That kind of person is also difficult to find.
Any reputable source will report mutual fund and stock returns as “annualized” figures, which takes the sequence of returns into account. Another term for this is “geometric average”, which again accounts for the order in which returns are received. So while there are some financial “experts” out there touting average returns (cough, Dave Ramsey), for the most part what you’re talking about here is not a factor.
