About 40 ETFs Halted Amid Volatility Brake Implementation
This article is for subscribers only.
Trading was briefly halted today in about 40 exchange-traded funds and notes when the securities were added to a program aimed at curbing sudden price swings.
Most of the ETNs and ETFs trade so seldom that there probably wouldn’t have been any transactions even if they hadn’t been halted, data compiled by Bloomberg show. They were set off during implementation of the protocol known as limit up/limit down that pauses securities when bid-ask spreads become too wide, according to NYSE Euronext.
