Boglehead-style investing at Northern
The building blocks of Boglehead-style investing are low-expense-ratio index mutual funds and/or ETFs. Vanguard fans would suggest that Vanguard has the best and most complete lineup of such funds, and that the most convenient place to hold Vanguard mutual funds is directly at Vanguard. Thus, the Bogleheads forum and Wiki tends to be Vanguard-oriented. But investing according to the Boglehead philosophy certainly does not require you to invest at Vanguard or use Vanguard products. Here are some notes on how to do it at Northern.
