In this episode of the Bogleheads® on Investing podcast, host Jon Luskin, CFP®, sits down with Jay Jacobs, US Head of Equity ETFs at BlackRock, to answer community-submitted questions about how to invest simply and effectively for retirement. Jay oversees more than 300 iShares ETFs spanning US equity, international, outcome, and digital asset strategies, and brings deep institutional expertise to the Bogleheads community's most pressing investing questions.

Jon and Jay explore the powerful tax-efficiency advantages of ETF structures over mutual funds, particularly for investors using all-in-one and target-date products in taxable brokerage accounts. The conversation covers how ETFs use in-kind creation/redemption mechanisms to minimize capital gains distributions, a significant edge over traditional mutual funds.

The episode dives into the research and methodology behind glide path design, including how demographic shifts (people working and living longer), inflation expectations, and capital markets assumptions all influence how the stock/bond mix evolves over an investor's lifetime. Jay explains the rationale behind the LifePath funds' 40% stock/60% bond terminal allocation, why a market-weight approach to international exposure makes sense for long-term investors, and more.
