TY - JOUR T1 - The Effect of Tripping the US Equity Market-Wide Circuit Breaker on Liquidity: Evidence from the Coronavirus Selloff JF - The Journal of Investing SP - 21 LP - 34 DO - 10.3905/joi.2022.1.230 VL - 32 IS - 1 AU - Charles Favreau AU - Ryan Garvey Y1 - 2022/11/30 UR - https://pm-research.com/content/32/1/21.abstract N2 - We examine changes in market liquidity around the triggering of US equity market-wide circuit breakers (MWCBs). The coronavirus pandemic has led to heightened market volatility and the tripping of four MWCBs in 2020. When the market reopens following an MWCB halt, trading demand (volume) surges. The rise in trading coincides with shifts in trading activity across exchanges and dark markets, and the cost of trading rises significantly. Although the market is less liquid immediately after a halt, conditions steadily improve over time and converge to similar levels on days in which the MWCB does not trip. ER -
