Jay Jacobs, U.S. head of equity ETFs at BlackRock, says that the artificial-intelligence revolution has delivered massive spending, but not at levels that have been spent relative to gross domestic product, during other generational shifts like the introduction of the automobile. As a result, while he understands the bubble concerns, he expects AI to continue holding its place among BlackRock's global thematic trends. Also on that list of trends is geopolitical shifts, which were well underway before current events evolved into a war in Iran; because those trends were in place before today's developments, Jacobs says he doesn't expect markets or outlooks to be dramatically impacted by headline events. Jacobs also discusses the new iShares Staked Ethereum fund, a new development in the crypto space, which the firm is launching today.

Wade Pfau, professor of retirement income, at The American College of Financial Services, discusses his revised, third edition of "Retirement Planning Guidebook: Navigating the Important Decisions for Retirement Success," which includes a new section covering sequence-of-inflation risk. Pfau says that concern -- which financial advisers mostly overlooked -- is particularly important now given growing concerns about sticky inflation, and that it may be as important for retirement savers as sequence-of-return risk, which Chuck typically says is his biggest retirement-savings worry.

Plus, Todd Rosenbluth, head of research at VettaFi, leans into global turmoil this week, picking a diversified international fund as his ETF of the Week.
