FYI: After a year that has reignited concerns about how exchange-traded funds work during volatile periods, junk bond ETFs came through a test this month, registering their highest trading volumes ever without any major disruption.
The December selloff of high-yield bonds did not spark the kinds of price distortions that have occasionally roiled ETF markets, potentially soothing fears about the way the products trade as regulatory scrutiny ramps up.
