In a recent Reuters article, SVP Steve Schweitzer discusses why few ETF options are offered in workplace retirement plans. While the differences between ETFs and mutual funds confuse many people, a big hurdle has been technological. ETFs trade throughout the day while mutual funds are typically priced on a daily basis causing a change in recordkeeping systems. “For a company deciding among offerings, one key is to consider your objectives,” says Schweitzer. If a participant’s plan does not offer ETF options but he or she is interested in them, a borkerage window within the 401(k) would allow the participant to trade whatever they want, at their own risk.
