The best Index Funds newsletters

A Vanguard-focused investing newsletter covering Vanguard product and service changes, a new PRIMECAP ETF, and annual scrutiny of Vanguard trustees' fund ownership. It gives readers practical portfolio guidance and independent analysis of fund-company governance, though it is explicitly unaffiliated with Vanguard.

This is the blog of Finizens, a Spanish robo-advisor, and its recent posts are mainly product launches and company milestones. Readers get announcements about its investment technology and pension plan, with promotional tone and little analytical depth in the excerpts.
